CanBus library for STM32F103 running on STM32duino, tested on F103C8T6 variant.Key advantages:
- Object-oriented programming style
- Support for inline Can::Frame initialization
- Support for 33.3KBPS CAN (GMLAN/SWCAN)
Inner workings based onnopnop2002's sketch.
STM32F103 pinouts:
enum Can::Pinout { RX_PA11_TX_PA12,// 36/48/64/100/144 pin packages RX_PB8_TX_PB9,// 48/64/100/144 pin packages RX_PD0_TX_PD1,// 100/144 pin packages};
Bitrates:
enum Can::Bitrate { CAN_33K3BPS, CAN_50KBPS, CAN_100KBPS, CAN_125KBPS, CAN_250KBPS, CAN_500KBPS, CAN_1000KBPS,};classCan::Frame {public:uint32_t id;uint8_t length;uint8_t data[8]; FrameFormat format; FrameType type;}
Types and formats:
enum Can::FrameFormat { Standard, Extended, };enum Can::FrameType { Data, Remote,};
#include"CanBus.hpp"usingnamespaceCan;CanBus can0;voidsetup() { Serial.begin(9600);bool ret = can0.begin(Bitrate::CAN_33K3BPS, Pinout::RX_PB8_TX_PB9); Serial.println(ret ?"BOOT OK" :"BOOT FAILURE");if (!ret)while(true);}Frame rx;Frame tx = {0x7FF,3, {0x01,0x02,0x03} };voidloop() {if(can0.checkReceive()) { can0.receive(&rx); rx.print(); } tx = {0x17FF,3, {0x01,0x02,0x03}, FrameFormat::Extended, FrameType::Data }; can0.send(&tx);}
