I am replacing an Arduino Uno with a Spark Core. I used to run SoftwareSerial to send data to these very nice and expensive screens: http://www.seetron.com/glo416.html
They require an inverted serial signal, with the last argument as a 1 using the SoftwareSerial library. This is a working line in my Arduino Uno code, as an example:
SoftwareSerial oled1 = SoftwareSerial(254,2,1); //rx pin=255 (an unused pin), tx pin=2, 1=inverted signal
Will I be able to use the Spark Core Serial1 and Serial2 abilities and configure them with this inverted signal? How would I go about implementing that? Thanks for you insight!
Resolution: No, you cannot currently invert the serial output from the Core.
