PICO Version & PICO 2 chip - How to Setup for C Language

1

Hi Forum,

I am in need of using PI PICO 1 & 2 Boards, of using C Language, and was wondering for recommendations of how to setup for Creating C Files and compile to executable ie blick.uf2

I have Visual Studio Code installed, but yet to buy the PI Debugger Probe.

Also need to use PIO Code as well

I have found the the C/C++ SDK files and the Getting Started… and the example projects but do not know if it is the correct setup.

I need to be able to send and receive packets of up to 72 bits in length, and the reassemble the reply packet. Each packet has a min. of 5ms quiet between each packet. It is one way.

The idea is to create a low cost DCC Master station (model trains), and a separate DCC Packet Sniffer which decodes the packet. a Bit = 1 → 58us +/-3us Bit = 0 → 100us +/-5us.

I have the basics working in micropython - sending and receiving bits. Yes I am using PIO code in both the transmitter PICO V1 and the separate receiver PICO V1.

Any recommendations for setting up in C environment will be greatly appreciated.

Thanks,
Geoff Cole

As I assemble more code to reassemble the sent packetI fear that I mayt start missing sent bits

CMake is essential for building projects on the Raspberry Pi Pico. In VSCode, you should configure your workspace to use CMake:

  1. In the root of your project folder, create a CMakeLists.txt file.
  2. Point it to the appropriate SDK and include the basic setup from the example projects
