Hi,
I wondering if is possible to swap the SPI pins (SDI/MISO, SDO/MOSI) of the Thing Plus Eplorable with Apollo3, in the Arduino code.
By default they are routed like this:
SDI/MISO = 25
SDO/MOSI = 28
With the Apollo3 example Example06_SPI is possible to change the pin definitions. Adapted in my code, it compiles and download, but then get error.
here a snip of the code
but then I get this error
Tnx

Code:
#include "SPI.h"#define SPI_MODE SPI_MODE3//MbedSPI mySPI(mySDI, mySDO, myCLK);MbedSPI spiPort(28, 25, 27);.. spiPort.begin(); // Do a fake transaction to initialize the SPI pins spiPort.beginTransaction(SPISettings(4000000, MSBFIRST, SPI_MODE3)); spiPort.transfer(0); spiPort.endTransaction();..but then I get this error
++ MbedOS Error Info ++any idea where the propblem is?
