I'm reading data from Satec PMEH130 Plus. When I parse the modbus responses, every number is correct, except from the negative ones, it should return something like -997, but it returns 655xx.. Is there fix for the parsing the negative numbers?
Here's my code:
I send this request to the device:
} else if ( testCount == 2 ) {
buffer[0] = 0x01;
buffer[1] = 0x03;
buffer[2] = 0x34;
buffer[3] = 0x18;
buffer[4] = 0x00;
buffer[5] = 0x0c;
buffer[6] = 0xcb;
buffer[7] = 0xf8;
lab = 'KVAL1, KVAL2, KVAL3, PFL1, PFL2, PFL3';
Device returns modbus string:
010318000000000000000000000000fc1dfffffc20fffffc1bffff4fa1
This is my modbus parse function:
function parseModbus(hexString, type)
{
var LVAL = hexString.substr(4,2);
LVAL = parseInt(LVAL, 16);
var values = hexString.substr(6, (LVAL*2)).match(/.{1,4}/g);
switch(type)
{
case 2:
if(values) {
//console.log(values.length);
kVAL1 = parseInt(values[0], 16);
kVAL2 = parseInt(values[2], 16);
kVAL3 = parseInt(values[4], 16);
PFL1 = parseInt(values[6], 16);
PFL2 = parseInt(values[8], 16);
PFL3 = parseInt(values[10], 16);
}
break;
}
The incorrect values are in PFL1, PFL2 and PFL3. Thanks.
Ok, figured it out. You have to substract the value with 65536.
PFL1 = parseInt(values[6], 16) - 65536;

I am trying to implement Variable Rate Shading in the app based on DirectX 11.
I am doing it this way:
UINT dwRtWidth = 2560;
UINT dwRtHeight = 1440;
D3D11_TEXTURE2D_DESC srcDesc;
ZeroMemory(&srcDesc, sizeof(srcDesc));
int sri_w = dwRtWidth / NV_VARIABLE_PIXEL_SHADING_TILE_WIDTH;
int sri_h = dwRtHeight / NV_VARIABLE_PIXEL_SHADING_TILE_HEIGHT;
srcDesc.Width = sri_w;
srcDesc.Height = sri_h;
srcDesc.ArraySize = 1;
srcDesc.Format = DXGI_FORMAT_R8_UINT;
srcDesc.SampleDesc.Count = 1;
srcDesc.SampleDesc.Quality = 0;
srcDesc.Usage = D3D11_USAGE_DEFAULT; //Optional
srcDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE; //Optional
srcDesc.CPUAccessFlags = 0;
srcDesc.MiscFlags = 0;
D3D11_SUBRESOURCE_DATA initialData;
UINT* data = (UINT*)malloc(sri_w * sri_h * sizeof(UINT));
for (int i = 0; i < sri_w * sri_h; i++)
data[i] = (UINT)0;
initialData.pSysMem = data;
initialData.SysMemPitch = sri_w;
//initialData.SysMemSlicePitch = 0;
HRESULT hr = s_device->CreateTexture2D(&srcDesc, &initialData, &pShadingRateSurface);
if (FAILED(hr))
{
LOG("Texture not created");
LOG(std::system_category().message(hr));
}
else
LOG("Texture created");
When I try to create texture with initial data, it is not being created and HRESULTS gives message: 'The parameter is incorrect'. Doesn't say which one.
When I create texture without initial data it's created successfully.
What's wrong with the initial data? I also tried to use unsigned char instead of UINT as it has 8 bits, but result was the same, texture was not created.
Please help.
Aftr some time I found a solution to the problem. I needed to add a line:
srcDesc.MipLevels = 1;
With this change the texture was finally created with initial data

how to store this in array
That is a Dictionary. It is easy to get just the data without the keys.
In Objective-C it would be :
NSArray *allData = [jsonResult1 allValues];
For swift it should be like: (not sure about syntax)
var allData = jsonResult1.allValues()
If you're up for it, you should give SwiftyJSON a try.
https://github.com/SwiftyJSON/SwiftyJSON
I've recently used it for an application that deals with a ton of JSON responses from a web service and SwiftyJSON has made it super easy for me to deal with JSON data in Swift. It will convert NSData to Dictionaries or Arrays seamlessly for you.
I have used the following Objective C routines for years, to convert a NSData push token into a NSString (for use by a web side push service), and the inverse, to take a known NSString version of the token and recreate the NSData representation. Now, I find the need for the exact same capabilities, but in Swift.
The dataToHex Objective C code essentially uses printf formatting:
- (NSString *)dataToHex:(NSData *)data
{
NSMutableString *str = [NSMutableString stringWithCapacity:100];
const unsigned char *p = [data bytes];
NSUInteger len = [data length];
for(int i=0; i<len; ++i) {
[str appendFormat:#"%02.2X", p[i]];
}
return str;
}
The inverse translation is:
- (NSData *)hexToData:(NSString *)str
{
const char *ptr = [str cStringUsingEncoding:NSASCIIStringEncoding];
NSUInteger len = [str length]/2;
NSMutableData *data = [NSMutableData dataWithCapacity:len];
while(len--) {
char num[5] = (char[]){ '0', 'x', 0, 0, 0 };
num[2] = *ptr++;
num[3] = *ptr++;
uint8_t n = (uint8_t)strtol(num, NULL, 0);
[data appendBytes:&n length:1];
}
return data;
}
By "cleverly" overwriting a two byes in an ASCII array, the "0xXX" string is converted into a byte, which is then appended to the mutable data object.
Now that I'm coding in Swift, I need the same capabilities but have not found any posts with anything like the code above in Swift.
Converting from the NSData representation as supplied by iOS matches the Objective C code almost line for line:
func dataToHex(data: NSData) -> String
{
var str: String = String()
let p = UnsafePointer<UInt8>(data.bytes)
let len = data.length
for var i=0; i<len; ++i {
str += String(format: "%02.2X", p[i])
}
return str
}
However, given an NSString object, the conversion back to a NSData object is a bit harder. You might need to do this if you are testing in the Simulator, have a string token from a real device, and need it to say register with a service.
The first approach I took tried to replicate code I used before, by creating a string with character pairs, and calling strtol:
func hexToData0(str: NSString) -> NSData {
let len = str.length/2
var data = NSMutableData(capacity:len)!
var num: [Int8] = [ 0, 0, 0 ]
let ptr = str.cStringUsingEncoding(NSUTF8StringEncoding)
for var i=0; i<len; ++i {
num[0] = ptr[i*2+0]
num[1] = ptr[i*2+1]
var n = UInt8 ( strtol(&num, nil, 16) )
data.appendBytes(&n, length:1)
}
return data;
}
I just felt the strtol was a bit of a hack, so I did the same using NSScanner that about the same code size, while most likely less efficient:
func hexToData1(str: NSString) -> NSData {
var data = NSMutableData(capacity: str.length/2)!
for var i = 0; i<str.length; i+=2 {
let r = NSRange(location: i, length: 2)
let s = str.substringWithRange(r)
let sc = NSScanner(string: s)
var val: UInt32 = 0
let ret = sc.scanHexInt(&val)
if ret {
var b = UInt8(val)
data.appendBytes(&b, length: 1)
} else {
assert(false, "Yikes!")
}
}
return data
}
Then, it occurred to me that I could do it all in Swift, no Darwin or Foundation needed, at the expense of a few more lines of code:
// Swift 4
func hexToData(str: String) -> Data {
let len = str.count/2
var data = Data(capacity:len)
let ptr = str.cString(using: String.Encoding.utf8)!
for i in 0..<len {
var num: UInt8 = 0
var multi: UInt8 = 16;
for j in 0..<2 {
let c: UInt8 = UInt8(ptr[i*2+j])
var offset: UInt8 = 0
switch c {
case 48...57: // '0'-'9'
offset = 48
case 65...70: // 'A'-'F'
offset = 65 - 10 // 10 since 'A' is 10, not 0
case 97...102: // 'a'-'f'
offset = 97 - 10 // 10 since 'a' is 10, not 0
default:
assert(false)
}
num += (c - offset)*multi
multi = 1
}
data.append(num)
}
return data;
}
I'm using the final hexToData in my code.
I'm requesting a SOAP Webservice and I parse the response to a NSDictionary. The XML response has multiple unique keys. Here's an example (already parse on the dictionary):
"typ:partits" = {
"typ:dadesPartit" = {
"typ:aforament" = 1;
"typ:codiEsdeveniment" = 2;
"typ:competicio" = GAMPER;
"typ:dataHoraConfirmada" = false;
"typ:dataPartit" = "08/18/14";
"typ:descripcioPartit" = "FCBARCELONA - CLUB LEON F.C.";
"typ:horaPartit" = "9:30:00 PM";
"typ:jornada" = 99;
"typ:partitActiuMenor" = true;
"typ:temporada" = "2014-2015";
"typ:tipusEsdeveniment" = 0;
},
"typ:dadesPartit" = {
"typ:aforament" = 1;
"typ:codiEsdeveniment" = 2;
"typ:competicio" = GAMPER;
"typ:dataHoraConfirmada" = false;
"typ:dataPartit" = "08/26/14";
"typ:descripcioPartit" = "FCBARCELONA - REAL MADRID";
"typ:horaPartit" = "9:30:00 PM";
"typ:jornada" = 101;
"typ:partitActiuMenor" = true;
"typ:temporada" = "2014-2015";
"typ:tipusEsdeveniment" = 0;
};
};
How can I iterate through these keys?, they are the same :( ...
I tried with "allObjects" but when I receive only one "typ:dadesPartit" object it treats it like an array instead of a NSDictionary.
it is returning one type as both your keys are same,
Try renaming the keys to separate names, and the values associated with those keys will come when u type allKeys
I want to inject touch event in iPhone. I get the coordinates of touch event via network socket. GSSendEvent seems to be good choice. However, it needs GSEventRecord as one of the inputs.
Does anyone know how to prepare GSEventRecord? I prepared it based on some examples but the app crashes after GSSendEvent call.
Appreciate any help.
-(void) handleMouseEventAtPoint:(CGPoint) point
{
static mach_port_t port_;
// structure of touch GSEvent
struct GSTouchEvent {
GSEventRecord record;
GSHandInfo handInfo;
} ;
struct GSTouchEvent *touchEvent = (struct GSTouchEvent *) malloc(sizeof(struct GSTouchEvent));
bzero(touchEvent, sizeof(touchEvent));
// set up GSEvent
touchEvent->record.type = kGSEventHand;
touchEvent->record.windowLocation = point;
touchEvent->record.timestamp = GSCurrentEventTimestamp();
touchEvent->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo);
touchEvent->handInfo.type = getHandInfoType(0, 1);
touchEvent->handInfo.pathInfosCount = 1;
bzero(&touchEvent->handInfo.pathInfos[0], sizeof(GSPathInfo));
touchEvent->handInfo.pathInfos[0].pathIndex = 1;
touchEvent->handInfo.pathInfos[0].pathIdentity = 2;
touchEvent->handInfo.pathInfos[0].pathProximity = 1 ? 0x03 : 0x00;
touchEvent->handInfo.pathInfos[0].pathLocation = point;
port_ = GSGetPurpleSystemEventPort();
GSSendEvent((GSEventRecord*)touchEvent ,port_);
}
static GSHandInfoType getHandInfoType(int touch_before, int touch_now){
if (!touch_before) {
return (GSHandInfoType) kGSHandInfoType2TouchDown;
}
if (touch_now) {
return (GSHandInfoType) kGSHandInfoType2TouchChange;
}
return (GSHandInfoType) kGSHandInfoType2TouchFinal;
}
Only tested on iOS 6
You are actually on the right track. The problem is you have to figure out what values you should assign to these variables.
First of all, you need to import GraphicsServices.h. Then, you can try the following code with the port which you can get from How to find the purple port for the front most application in IOS 5 and above?.
I am not an iOS expert and Apple doesn't provide any documentation so I can't explain much what's going on here. (It happens to work fine for me.)
Anyway, you can play with it using xcode debug mode to see what happens under the hood.
struct GSTouchEvent * touchEvent = (struct GSTouchEvent*) &gsTouchEvent;
bzero(touchEvent, sizeof(touchEvent));
touchEvent->record.type = kGSEventHand;
touchEvent->record.subtype = kGSEventSubTypeUnknown;
touchEvent->record.location = point;
touchEvent->record.windowLocation = point;
touchEvent->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo);
touchEvent->record.timestamp = GSCurrentEventTimestamp();
touchEvent->record.window = winRef;
touchEvent->record.senderPID = 919;
bzero(&touchEvent->handInfo, sizeof(GSHandInfo));
bzero(&touchEvent->handInfo.pathInfos[0], sizeof(GSPathInfo));
GSHandInfo touchEventHandInfo;
touchEventHandInfo._0x5C = 0;
touchEventHandInfo.deltaX = 0;
touchEventHandInfo.deltaY = 0;
touchEventHandInfo.height = 0;
touchEventHandInfo.width = 0;
touchEvent->handInfo = touchEventHandInfo;
touchEvent->handInfo.type = handInfoType;
touchEvent->handInfo.deltaX = 1;
touchEvent->handInfo.deltaY = 1;
touchEvent->handInfo.pathInfosCount = 0;
touchEvent->handInfo.pathInfos[0].pathIndex = 1;
touchEvent->handInfo.pathInfos[0].pathIdentity = 2;
touchEvent->handInfo.pathInfos[0].pathProximity = (handInfoType == kGSHandInfoTypeTouchDown || handInfoType == kGSHandInfoTypeTouchDragged || handInfoType == kGSHandInfoTypeTouchMoved) ? 0x03: 0x00;
touchEvent->handInfo.x52 = 1;
touchEvent->handInfo.pathInfos[0].pathLocation = point;
touchEvent->handInfo.pathInfos[0].pathWindow = winRef;
GSEventRecord* record = (GSEventRecord*) touchEvent;
record->timestamp = GSCurrentEventTimestamp();
GSSendEvent(record, port);
To use this code, you have to call it multiple times. For one tap, there are touch-down, touch-drag and then touch-up.
Also note that pathProximity is 0 when touch is up.
As far as I remember, the winRef doesn't matter.
Hope this helps.
Edit: From Bugivore's comment, the problem is:
The way I allocated touchEvent via malloc was wrong. It should be done as EntryLevelDev showed - "static uint8_t handJob[sizeof(GSEventRecord) + sizeof(GSHandInfo) + sizeof(GSPathInfo)];"
Answer from EntryLevelDev is correct, but some of the value is not so important. I got the below codes from somewhere else and have done some try and errors, here is my codes(worked for till latested ios6).
And is anyone working on this for IOS7 now? I could not get it to work. see my post here:With GSCopyPurpleNamedPort(appId) in GraphicsServices deprecated in IOS7, what is the alternative approach?
static int prev_click = 0;
if (!click && !prev_click)
{
//which should never enter
NSLog(#"***error, postHandEvent cancel");
return;
}
CGPoint location = CGPointMake(x, y);
struct GSTouchEvent {
GSEventRecord record;
GSHandInfo handInfo;
} * event = (struct GSTouchEvent*) &touchEvent;
bzero(touchEvent, sizeof(touchEvent));
event->record.type = kGSEventHand;
event->record.windowLocation = location;
event->record.timestamp = GSCurrentEventTimestamp();
//NSLog(#"Timestamp GSCurrentEventTimestamp: %llu",GSCurrentEventTimestamp());
event->record.infoSize = sizeof(GSHandInfo) + sizeof(GSPathInfo);
event->handInfo.type = getHandInfoType(prev_click, click);
//must have the following line
event->handInfo.x52 = 1;
//below line is for ios4
//event->handInfo.pathInfosCount = 1;
bzero(&event->handInfo.pathInfos[0], sizeof(GSPathInfo));
event->handInfo.pathInfos[0].pathIndex = 2;
//following 2 lines, they are by default
event->handInfo.pathInfos[0].pathMajorRadius = 1.0;
event->handInfo.pathInfos[0].pathPressure = 1.0;
//event->handInfo.pathInfos[0].pathIdentity = 2;
event->handInfo.pathInfos[0].pathProximity = click ? 0x03 : 0x00;
//event->handInfo.pathInfos[0].pathProximity = action;
event->handInfo.pathInfos[0].pathLocation = location;
// send GSEvent
GSEventRecord *event1 = (GSEventRecord*) event;
sendGSEvent(event1);
