I am trying to use an external switch with a Plasma 2350W and a program written in circuitpython. I don;t know how to access the SWC or SWD in circuitpython. The schematic says SWC shares the SWCLK pin. That’s not defined in “board” either. Any idea on how to get this to work?
The debug pins of a Pico (SWC, SWD, GND) are for connecting a debug-probe to the Pico and are used for low-level C-programming. These pins are never accessible from xxxPython.
For an external switch, you can use any of the pins exposed on the header. As long as you don’t use the UART/I2C/ADC-pins for UART/I2C/ADC, you can use them as normal digital IO pins.
Thank you for the response. I guess I just assumed that SWC and SWD followed the SWA and SWB switch pattern….
Indeed this is confusing, especially because Pimoroni uses these terms on other boards/breakouts for buttons labelled A, B, C.
