I'm currently doing a CANFD loopback test.

I want to use a filter so that I can communicate with only 10 types of IDs.

However, I feel that the following four types cannot be achieved.

[stm32h7xx_hal_fdcan.h(1021)]​

sFilterConfig.FilterType =

1. FDCAN_FILTER_RANGE;
2. FDCAN_FILTER_DUAL;
3. FDCAN_FILTER_MASK;
4. FDCAN_FILTER_RANGE_NO_EIDM;

The IDs I wanted to allow in the filter were not consecutive numbers.

for example [0x111, 0x122, 0x069, 0x013, 0x0A0, 0x090, 0x055, 0x0AA, 0x101, 0x003]

So I thought about using multiple FILTER_DUAL, but neither was successful.

 /* Configure Rx filter 1 */

 sFilterConfig.IdType = FDCAN_STANDARD_ID;

 sFilterConfig.FilterIndex = 0;

 sFilterConfig.FilterType = FDCAN_FILTER_DUAL;

 sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;

 sFilterConfig.FilterID1 = 0x111;

 sFilterConfig.FilterID2 = 0x7FF; 

HAL_FDCAN_ConfigFilter(&hfdcan, &sFilterConfig);

 /* Configure Rx filter 2 */

 sFilterConfig.IdType = FDCAN_STANDARD_ID;

 sFilterConfig.FilterIndex = 1;

 sFilterConfig.FilterType = FDCAN_FILTER_DUAL;

 sFilterConfig.FilterConfig = FDCAN_FILTER_TO_RXFIFO0;

 sFilterConfig.FilterID1 = 0x122;

 sFilterConfig.FilterID2 = 0x7FF; 

HAL_FDCAN_ConfigFilter(&hfdcan, &sFilterConfig);

1. Do the indexes match in the sense that they specify the number of filters to initialize? ( I don't really understand this filter index either...)
2. Is it possible to allow 10 different IDs using the filter function here?

solved.

It seems that the number of standard filters was not set correctly at the time of initialization.

 hfdcan.Init.StdFiltersNbr = 0; // before

 hfdcan.Init.StdFiltersNbr = 10; // after​Should have calmed down
