    Re: Drive Current Sufficiency

    As I said , I'll design the PCB according to the technical specs of all these ICs so measuring it will be possible only when the PCBs arrive .. But so far you've been very helpful to all my questions...

    Re: Drive Current Sufficiency

    Don't you think the current at 3.85 V proportionally should increase at 5V drive voltage..? Secondly do you have any idea with my other question ?

    Re: Drive Current Sufficiency

    Also do you think this MCU's weak current supplying ports can handle and succesfully drive the A/B/C/INH signal inputs of CD4051 and A/B/C/D/INH signal inputs of 4514 ?

    Re: SPI Commands Operating Speed

    Thanks for all the answers ..

    I measured the SCK frequency 333 khz at 64 mhz so I wish pbp had a modification parameter for it (since we can't use all the pins for hardware SPI purpose)
    Well ,...
