firmware

firmware (pdk-logic-probe)

Toolchain:

• The open-source Small Device C Compiler (SDCC)
  • Requires version 3.9.0 or newer - version 4.0.0+ preferred
• The open-source Easy PDK Programmer
  • Requires version 1.3 or newer
• The open-source pdk-includes repository
  • Integrated via local copy into the pdk/ directory
• The open-source easy-pdk-includes repository
  • Integrated via local copy into the easy-pdk/ directory
• Also requires 'make' and other common build tools

Build Commands:

make clean
make build
make size (also calls build)
make program (also calls size which calls build)

Note: These commands can be chained as well. i.e. make clean program

Customization:

Edit the variables at the top of the Makefile to:

• DEVICE: Use a different Padauk MCU (defaults to PFS154)
• TARGET_VDD_MV: Use a different voltage while calibrating the internal oscillator (IHRC) (defaults to 3000mV)

Note: Both of these variables can be changed on the commandline as well. i.e. make DEVICE=PFS173 clean program

Compatibility

This project is currently intended to be run (without modifications) on the PFS154, PFS173, PMS150C/PMS15A, PMS152, PMS154C, and PMS171B Padauk microcontrollers, but it should be able to be modified to run on just about every currently known Padauk microcontroller that is supported by SDCC and the Easy PDK Programmer. Some microcontrollers will require additional definitions in the hal.h file, and less common devices may require additional device specific include files (pdk/device/*.h) to be supplied.

Build Stats

• Code Size: ~92-97 words (depending on the microcontroller)
• RAM usage: 0 bytes + stack
