We are currently working in a project where we are connecting and external accelerometer to the sensortag via SPI. But we have stumbled into a problem.
The board.h that comes with the sensortag application program has the SPI0 at IO17 but that pin seems to be used as well for the debugging, so when we try to debug we cannot generate clock to the SPI. We changed the pin to IO11 and it works fine, the problem is that we want to store the data from the accelerometer in the flash memory whose clock is hardwired to IO17.
We note that the sensortag application even though does not use the flash it does test it so the clock must be working during that test but we haven't been able to make the clock to work on IO17.
any way to solve this??
Thank you in advance...
