Thanks Windell! I will take take your advice and investigate the I2C and UART options.
Regarding the “SER” jumper option, wasn’t this was one of the improvements added to the 2.3 Board revision? I am working with a 2.2 Peggy Board so I don’t have the SER JP 1 / JP 2 section above the Prototype area on my board as outlined at step 6 of the manual.
Is there another work around for the 2.2 board to enable Peggy2serial library and use UART, or can I still use I2C without the SER jumper option?
