Colin McMillenIs there anything I should learn about signal integrity, ground planes, etc before routing a 4 layer #pcb that will do SPI and 250KHz signal handling? Or do I not care at these speeds?
Michel@colin_mcmillen dont care that much really. as long as you dont zigzag around high voltage rail lines etc 25mhz SPI is easy as pie!
@colin_mcmillen one thing that is "good practice" tho is to add a zero-R resistors in series on the data/clock lines. Likely wont need it, but in case you have too much "ringing" you can increase that a notch to help. Also serves as test point!
@buserror Thanks. I... didn't have room for that in the end.
