Hi,
For a project, I need to make a testbed (shield) for the ShieldBuddy. I need SPI to control a set of digital potentiometers.
As I need to place the digipots on the shield, I had wanted to use the SPI channels 1 or 2 (p12,11,13 or p50,51,52 - MOSI) instead of the P201.
I checked the manual, and I couldn't make it seem to work. (SPI.begin(BOARD_SPI_SS0_S1) etc.).
I was wondering if there is an example code how to use channels 1 or 2.
*I also tried looking in the Variant.h (C:\Program Files (x86)\Arduino\hardware\aurduino_Dx\aurix\variants\tc275) to find any clues if there are other pins that I need to declare to change the MOSI, MISO and SCK pins.
**I also tried setting the SPI pins, but Shieldbuddy's SPI library doesn't support the SPI.setMISO etc. to assign the SPI pins unlike the teensy.
***The Shieldbuddy's Spi ICSP P201 doesn't seem to be physically connected to the other pins (11,12,13,50,51, or 52) like the mega or uno.
Thank you.
