Microchip PIC
« on: May 23, 2020, 12:56:43 AM »

Driven by a motivation to keep busy whilst surviving adverse events in the news, I seem to be getting back into Microchip PIC, after a long absence of interest.

First impressions... wow, these chips can do more than ever. :)

Second impressions...  Eek, the IDE and sample projects, what a mess.   What used to be a few hundred lines of assembler in a single source file is now in C, and split between dozens of source files. Many of the C files are machine-generated by an obscure GUI configurator, completely impenetrable. :'(

But I am getting there, managed to make an LED flash this afternoon.  All that remains is to think of what on earth I will now do with a PIC, once I have mastered the technology again. ::)

Cool! What chips are you using?

Iíve built a few things with ESP32 boards.  Integrated WiFi, Bluetooth and BLE all on a tiny board.

My favourite board at the mo is the ESP32-PICO-V4.  Currently building a thing to interface Bluetooth game controllers with retro game consoles (specifically, an Atari Jaguar).

Iím relatively new to this. Got a Uni-level C/C++ education, but never used it professionally. Started out with the Arduino IDE before switching to Espressifís IDF framework.  I finally settled on Visual Studio Code with PlatformIO on top of the ESP-IDF.

Recently bought a JTAG debugger board so I can finally work with breakpoints, watches and step-through.

They really are quite amazing little devices!

I have an interest in the chips with on-board op amps, so I bought a Ďcuriosityí development board, along with some 16F chips with op amps.

And that is about as far as I have got so far.   To explore the op amps, I think I need to replace some zero ohm links with header pins and jumpers, which I donít yet have.   But I have certainly succeeded in installing sample code on a virgin device and running it. :)
