It is implemented in PIC16F887 assembler, and buildable using the FOSS gputils toolchain. This talk describes the reverse-engineering of the hardware, the layering of subsystems from HAL to UI, and implementation of the subsystems. Ideas for improvement and lessons learned.</p><h4class=title-description>Description</h4><pclass=description><p>This would be based on my blog post at <ahref=https://tommie.github.io/a/2024/03/foss-firmware-at860d>https://tommie.github.io/a/2024/03/foss-firmware-at860d</a>.</p><p>The code is available under GPL-3 at <ahref=https://github.com/tommie/at860d-firmware>https://github.com/tommie/at860d-firmware</a>.</p><p>A proof-of-concept of an event-based RTOS for PIC16F is in <ahref=https://github.com/tommie/dios>https://github.com/tommie/dios</a>, which is an extension to the code structure used in the firmware.</p><p>The duration is flexible 25-45 min, depending on the interests of the audience, and how deep they want to go on ZCC/PFC triac control, PIC assembler, and event-based vs state-based code structuring.</p><p>(The form required me to add a session image, so I did, though the text suggests it’s optional. :)</p></p></div><divclass="column left"id=details><h3>Info</h3><p><b>Day:</b>
