These are code examples for Padauk Microcontrollers. They are meant to be compiled with the Small Device C Compiler (SDCC). For pdk14 and pdk15, the SDCC backend is considered stable. For pdk13, the SDCC-based toolchain is still experimental as of 2019-06-09, so running into issues is to be expected. Currently, there are 4 demos: count-pfs154: A timer / LED example for the PFS154 and PFS173. hello-pfs15: A serial output example for the PFS154 and PFS173. timer_irq_blink: An example ported from MINI-C to SDCC: watchdog: An example ported from MINI-C to SDCC:
