hi all, Here in my CAN project i am using the Fujitsu controller (MB90F420).That has the two acceptance mask registers(AMR0,AMR1).I have set it in to the full bit compare mode using AMSR(Acceptance mask selection register).First i written the coding to transmit (Basic settings for transmissionm like initializing CAN,enabling and disabling the required transmission registers) only the extended data before that i set the Data and Message values in the corresponding ID and DATA registers. after set the values i enabled the transmission request(TREQ = 1).I have enabled the interrupt also. here is my qns.
- As soon as i enabled the TREQ,will the transmission starts or shold i write the Transmission routine of this data and ID in the interrupt service routines,bcoz i have enabled the Tx intererupt.
- while receiving these data and ID value, how should i utilize the acceptance mask registers for Comparision,or the CAN itself do the comparision?.
Plz clear my doubts
