I have a project that uses 3 CAN busses : 500k 11bit , 500k 29bit and 83k 11 bit .
I used a ZX24s when i only had the 11bit busses , but now i needed to add the 29bit also and i needed 3 hw serial ports so i swapped the 24s to a 24u .
I am close to clearing all buffers in time but occasionally one of the queues overflow .
I could filter out most of the 29bit traffic but the acceptance filter on the SJA1000 is incomprehensible to me ...
Has anyone used the SJA1000 and understood how the filter works ?
I only need to read 00200200 and 00200380 . . .
