/* * An example of using CAN bus with NUCLEO boards: * * Two affordable (less than $4 on ebay) STM32F103C8T6 boards (20kB SRAM, 64kB Flash), * compatible with the NUCLEO-F103RB platform (20kB SRAM, 128kB Flash), * are connected to the same CAN bus via transceivers (MCP2551 or TJA1040, or etc.). * CAN transceivers are not part of NUCLEO boards, therefore must be added by you. * Remember also that CAN bus (even a short one) must be terminated with 120 Ohm resitors at both ends. * * For more details see the wiki page [https://developer.mbed.org/users/hudakz/code/CANnucleo_Hello/] * * NOTE: If you'd like to use the official NUCLEO boards comment out line 24 * * The same code is used for both NUCLEO boards, but: * For board #1 compile the example without any change. * For board #2 comment out line 25 before compiling * * Once the binaries have been downloaded to the boards reset board #1. * */ #include "mbed.h" //#define TARGET_STM32F103C8T6 1 // comment out this line when using official NUCLEO boards! #define BOARD1 1 // comment out this line when compiling for board #2 #if defined(TARGET_STM32F103C8T6) #define LED_PIN PC_13 const int OFF = 1; const int ON = 0; #else #define LED_PIN LED1 const int OFF = 0; const int ON = 1; #endif #if defined(BOARD1) const unsigned int RX_ID = 0x100; const unsigned int TX_ID = 0x101; #else const unsigned int RX_ID = 0x101; const unsigned int TX_ID = 0x100; #endif DigitalOut led(LED_PIN); Timer timer; CAN can(PA_11, PA_12); // CAN Rx pin name, CAN Tx pin name CANMessage rxMsg; char counter = 0; int main() { #if defined(BOARD1) led = ON; // turn LED on timer.start(); // start timer #else led = OFF; // turn LED off #endif while(1) { if(timer.read_ms() >= 200) { // check for timeout timer.stop(); // stop timer timer.reset(); // reset timer counter++; // increment counter led = OFF; // turn LED off if(can.write(CANMessage(TX_ID, &counter, 1))) // transmit message printf("CAN message sent\r\n"); else printf("Transmission error\r\n"); } if(can.read(rxMsg)) { printf("CAN message received:\r\n"); printf(" ID = %#x\r\n", rxMsg.id); printf(" Type = %d\r\n", rxMsg.type); printf(" Format = %d\r\n", rxMsg.format); printf(" Length = %d\r\n", rxMsg.len); printf(" Data ="); for(int i = 0; i < rxMsg.len; i++) printf(" 0x%.2x", rxMsg.data[i]); printf("\r\n"); if(rxMsg.id == RX_ID) { counter = rxMsg.data[0]; // set counter printf("counter = %d\r\n", counter); // print counter led = ON; // set LED timer.start(); // transmission lag } } } }
