    bit banging spi, dont think im getting anywhere

    reading register 02, default values are %00000011 and logic says.......... now i just have to start looking at tidying things up and maybe a short pause before the gosub as my logic keeps saying the cs leading edge is missing, it doesnt do it all the time so maybe upping the sampling rate but...

    bit banging spi, dont think im getting anywhere

    hopefully this is a good sign but i finally got the data for one command i was expecting to see. hippy i put a 10k pulldown on the miso line and cleared up the noise and then moved my chip select commands to the main portion of the code as you suggested with them before the shiftout gosub and...

    i swapped out the 14m2 for a 20m2 just incase the chip has suffered from years of abuse but still similar results with a barely used and not abused 20m2 lol

    reflow pick & place?

    its not going to be as bad as it seems, you dont have to worry too much about 100% alignment as the solder will pull the components into place once it reflows. from experience i learned to redesign my board with pretty much all small components on one side and the bigger on the other, just so i...
