Hello, I am trying to connect my Nicla Sense ME with an additional external device through SPI. However using the SPI minimal example as found on the cheat sheet it seems there is only silence when monitoring the GPIO logic levels of CS, CIPO, COPI or SCLK with an Oszi. What am I missing? Thank you & Regards, Rob     #include <SPI.h> #include "Nicla_System.h" #define EPD_CS p29 void setup() { nicla::begin(); // initialise library nicla::leds.begin(); // Start I2C connection SPI.begin(); } void loop() { nicla::leds.setColor(green); //turn green LED on delay(1000); //wait 1 second nicla::leds.setColor(off); //turn all LEDs off delay(1000); //wait 1 second digitalWrite(EPD_CS, LOW); //pull down the CS pin SPI.transfer(0x00); // address for device, for example 0x00 SPI.transfer(0x01); // value to write digitalWrite(EPD_CS, HIGH); // pull up the CS pin }   ...
