SimPad

Various hacks for Padauk MCU, the infamous "0.03USD" microcontroller. This is work in progress, don't expect anything to be functional or useful.

Hardware

Experimental programmer for Padauk MCU based on Arduino Nano, currently living on a breadbord. Not ready for production use, but can maybe serve es a reference. See folder for a description of shortcomings.

If you are in need of a programmer for the Padauk MCU, please check out the EasyPDKProg.

Firmware

Firmware, very incomplete work in progress. Is currently able to program PMS150C, PFS154, PMS154C. Right now, no host communication is implemented and the binary needs to be pasted into the source. Debug output is sent to serial output at 115200 baud. Will program a "blinky" into PFS154C in the current configuration.

Protocol

Information on programming protocol

Toolchain

Toolchain based on EASYPDKPROG and SDCC. Includes a few examples.
