Hi,
Here's a puzzle!
I made some Compass breakout boards for an AK8963C chip. x5 (Iphone5)
I have PCBs x3, some with 3x different peripherals, using SPI. 1x PCB with only the Compass, and a simple program on the 18F4620.
I've been testing each peripheral on separate programs, till almost satisfied, they're working well. Untill I added them all into one program. Now the previouslt reliable Compass, sometimes works, some times doesn't, with no clue to why.
I've been on another forum, checking the PCBs continuity, also Digital analysis, oscilloscope, with no clear result.
If anyone has ideas what may be wrong, let me know, and I can repeat any test again, please?
