FDCAN Configuration on STM32H723ZGT6 Hi all,
I am configuring FDCAN3 on the STM32H723 to receive data for a specific ID, but I'm encountering an issue. Here's what I've done so far:
We have configured the FDCAN filter as follows:
Filter_config_def.IdType = FDCAN_STANDARD_ID;
Filter_config_def.FilterIndex = 0;
Filter_config_def.FilterType = FDCAN_FILTER_MASK;
Filter_config_def.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;
Filter_config_def.FilterID1 = 0x7E8;
Filter_config_def.FilterID2 = 0x7E8;
Filter_config_def.RxBufferIndex = 0;
Then, we applied the filter using:
if (HAL_FDCAN_ConfigFilter(&hfdcan3, &Filter_config_def) != HAL_OK) {
Error_Handler();
}
However, I am still receiving all IDs, such as 0x90, 0x7E8, and 0x110, even though I only expect 0x7E8. I would like to call the callback function only when data with ID 0x7E8 is received.
Here is the relevant configuration for FDCAN3:
hfdcan3.Instance = FDCAN3;
hfdcan3.Init.FrameFormat = FDCAN_FRAME_FD_
