    How do I modify my PIC microcontroller program to deliver 150 hz also with the existing 1hz output

    I have a PIC microcontroller that delivers a 1hz output at RB0 and I want to deliver a 150 hertz also to another pin--say RB3. The 150 hertz does not need to be accurate. How do I modify the program and keep the 1hertz code because it seems to be accurate with my 16mhz crystal. I use a PIC...

    Why J1939 XBR message checksum needs to be right shifted by 4 bit and added to the checksum ?

    Attached is External Brake Request(XBR) J1939 message checksum calculation. SAE J1939 Digital Annex(DA) specifies this checksum algorithm. The result of the calculation is 4-bit checksum. Why is checksum right shifted by 4 bits and added to checksum? Why not just take 4 least significant...

    Can CAN 2.0B and J1939 coexist in the same CAN Network?

    Please consider CAN communication network in a heavy vehicle: Steering Electronic Control Unit (ECU) has CAN 2.0B. It doesn't have J1939 stack. All other ECUs in this network are implemented with J1939 stack. Can CAN 2.0B coexist with J1939? What code changes are needed in steering ECU and...
