I am working on STM32F103 for a project with CAN. While working I set the CAN Test mode to Loopback in the ioc file, afterwards I set the test mode back to normal mode. but this change was not updated in the main.c file. In main.c file, the line in MX_CAN_Init(void) function still is as following.
hcan.Init.Mode = CAN_MODE_LOOPBACK;
I cleaned the project and then again built the project, still it is same, I tried to change the test mode multiple times, but every time it asks if code should be generated and I select yes, still the code is not changing. Why is this happening?
CAN configuration:
Generated code
static void MX_CAN_Init(void)
{
/* USER CODE BEGIN CAN_Init 0 */
/* USER CODE END CAN_Init 0 */
/* USER CODE BEGIN CAN_Init 1 */
/* USER CODE END CAN_Init 1 */
hcan.Instance = CAN1;
hcan.Init.Prescaler = 16;
hcan.Init.Mode = CAN_MODE_LOOPBACK;
hcan.Init.SyncJumpWidth = CAN_SJW_1TQ;
hcan.Init.TimeSeg1 = CAN_BS1_2TQ;
hcan.Init.TimeSeg2 = CAN_BS2_1TQ;
hcan.Init.TimeTriggeredMode = DISABLE;
hcan.Init.AutoBusOff = DISABLE;
hcan.Init.AutoWakeUp = DISABLE;
hcan.Init.AutoRetransmission = DISABLE;
hcan.Init.ReceiveFifoLocked = DISABLE;
hcan.Init.TransmitFifoPriority = DISABLE;
if (HAL_CAN_Init(&hcan) != HAL_OK)
{
Error_Handler();
}
/* USER CODE BEGIN CAN_Init 2 */
/* USER CODE END CAN_Init 2 */
}
