STM32F103 CAN Arbitration lost I have a problem using CAN on STM32F103C8T6. I use this MCU on a bluepill board,a SN64HVD230 based CAN PHY and on the other end of the CAN bus a PiCAN2 board onRaspberry Pi. I drew a picture to show my setup:I want to have a 500 kbit/s-CAN-connection, I use the MCU with 16 MHz.My initialization code (I use the STM32-HAL-API) for the CAN is the following:#define CAN_RX_PORT GPIOA
#define CAN_RX_PIN LL_GPIO_PIN_11
#define CAN_TX_PORT GPIOA
#define CAN_TX_PIN LL_GPIO_PIN_12
void init_can_gpios(void){
LL_GPIO_SetPinMode(CAN_RX_PORT, CAN_RX_PIN, LL_GPIO_MODE_INPUT);
LL_GPIO_SetPinPull(CAN_RX_PORT,CAN_RX_PIN,LL_GPIO_PULL_UP);
LL_GPIO_SetPinMode(CAN_TX_PORT, CAN_TX_PIN, LL_GPIO_MODE_ALTERNATE);
LL_GPIO_SetPinSpeed(CAN_TX_PORT, CAN_TX_PIN, LL_GPIO_SPEED_FREQ_HIGH);
LL_GPIO_SetPinOutputType(CAN_TX_PORT,CAN_TX_PIN,LL_GPIO_OUTPUT_OPENDRAIN);
}
void init_can_periph(void){
LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_CAN1);
__HAL_RCC_CAN1_CLK_ENABLE();
