Hello,
I’m using U blox-C027 and I’m using 7 threads in my code. I’ve already define my threads as the following:
Thread GNSS_UDP(osPriorityNormal, 2000); //sending to the FMS the GNSS data
Thread GNSS_PB_UDP(osPriorityNormal, 2000); // Sending the Push button 1 with the GNSS data to the truck
Thread TCP_Server(osPriorityNormal, 2000); //TCP server thread FMS
Thread Temp_Sensor(osPriorityNormal, 2000); //TCP server thread FMS
//test threads
Thread Safety_Relay(osPriorityNormal, 2000);
Thread UDP_Socket(osPriorityNormal, 2000);
indent preformatted text by 4 spaces
I have athread for reading push button each 5ms and then sending the status of the push buttons via UDP socket as the following
void Safety_Relay_Thread()
{
printf("Safety \n\r");
