... if it's only 56 LEDs, it's as easy as to plug in the chip and do mov PORTn,#data ;n=0..6.
While to get the Triscend/Zylogic running I assume you'd have to perform a long sequence of weird operations to get a proper configuration into the FPGA... I see an order of magnitude of difference. OK I did not try, you did, you tell... JW |
