nmea date field looks like: 090914 (European) P = strchr(p, ',') +1 // move pass for date DDMMYY Void glcd_tiny_draw_string(int x, int y, char* c) double atof(const char *str) // elimited Limor's float implementation Uint8_t hour, minute, seconds //, year, month, day Global variables use 16 bytes (0%) of dynamic memory, leaving 2,032 bytes for local variables. Sketch uses 504 bytes (1%) of program storage space. PinMode(PA7, INPUT_PULLUP) // Set pin to input PinMode(PA6, INPUT_PULLUP) // Set pin to input PinMode(PA5, INPUT_PULLUP) // Set pin to input PinMode(PA4, INPUT_PULLUP) // Set pin to input PinMode(PA3, INPUT_PULLUP) // Set pin to input PinMode(PA2, INPUT_PULLUP) // Set pin to input PinMode(PA1, INPUT_PULLUP) // Set pin to input PinMode(PA0, INPUT_PULLUP) // Set pin to input
Serial.begin(115200) // Init serial communication #define GP 0xA001 //generating polynomial #define SEED 0xFFFF //initialization for CRC16 I know that its sort of unfair to post above question but I'm all out of ideas at the moment.Ĭode: Select all //*****start plain modbus***** There is still 2 differences that I can see:Ģ if ( Serial.available() = 8 ) vs while (Serial.available() > 0)īut can they be the cause, as the request is Hex and triggers response depending on which application sends it?
Using realterm my skecth sends out the correct response verifiable by both realterm and devicemonitoringstudioīut using Mach my skecth does not respond anything? The response is the same also when I use realterm to send the request (in hex) I can see both the request "0x01 0x04 0x00 0x00 0x00 0x31 0xca" from Mach and the response The plain modbus sketch works on both pills. My Setup is win7 with Roger's core 1.6.9IDE and 2 bluepills connected through a USB hub. I added the first 3 lines and the Reply_Inputs() function from plain modbus to my sketch I changed line 118 to line 119 and added lines 131,132 and 133 as per snippet below. SerialCommand library to also respond to modbus message. However I want to keep the ability to receive serial (ASCII) messages already implemented so I modified the
Which is read by Mach giving expected results. It reads the message from Mach and sends response I found the sketch (plain modbus)at the end of this post online. Now I need to add ModBus to my project so that I can pass messages to Mach3. I have so far been using this for my comms with success.
