Hello everyone I try to communication with canbus protocol on stm32f429 discovery. but to send data and recieving data are not reguarly. for example, firs data is came, after second data recieved late.

keep working on the receiver,

are you getting the fifo interrupts ?

for both fifos ? on some processors there are separate Rx_fifo interrupts.

you have to pull the data away under interrupt,

otherwise you will drop frames since the fifos are full.

I see, but firstly, I request for a packet, then I will recieve packet. but stm32f4 received very late and request very late
