Re: Arduino Serial Plotter 2.0

I'm not sure this is still very beta and the Arduino devs would probably want to change most of how I did it is my feeling, I'll keep you updated.

Arduino Serial Plotter 2.0

Been working on this for awhile now but its to point I feel comfortable sharing now. I'm going to post on a few other forums to get idea if this is something people would like to see? The code is still very much beta but this video demo shows that its fairly useful in its current state. Let know wha...

Re: Increase ULP program size

You can try to edit the sdkconfig file in your esp32-arduino install. Search for CONFIG_ULP_COPROC_RESERVE_MEM and add more memory like 1024. My sdkcofig file was located in ../tools/sdk/

Re: esp32 ulp programming

A recent update to the Arduino-core made the arduino_ulp incompatible so I updated my platform.txt to work with latest core and have the latest fixes. This has the unfortunate effect of making older core installation incompatible with this so you may have to update your core before this will work.

Re: esp32 ulp programming

If it doesn't yet run under CPython, i think it would not be too hard to make it run there. Most of the implementation seems to be pretty standard python3, as far as i can tell. Sorry that I didn't add a link in my previous comment: https://github.com/ThomasWaldmann/py-esp32-ulp From what I read, C...

Re: esp32 ulp programming

Hey, sorry random question, just wondering if anyone knows why Programming the ULP using macros became legacy. I was kinda thinking it was an easy and effective way with out the need of additional build tools. Trying to program the ULP using ESP32 Arduino and cant figure out the "proper" way yet, b...

Re: esp32 ulp programming

I have recently added support for multiple ulp assembly files and hopefully window and linux support but those need to be tested by someone that has those OS's.

Re: esp32 ulp programming

I got the files uploaded to github with a little how-to as the readme. If anyone tries this out let me know any problems you have with compiling a project here or in the github repository.

Re: esp32 ulp programming

Just a follow-up to this thread, I am successfully loading the ulp binary blob into the final elf and running a test sketch using the ulp to increment a global variable. Looks like I can use .s extension for ulp assembly and .S for xtensa assembly and have a python script do the heavy lifting of cre...

Re: esp32 ulp programming

If you’re on a linux or other Unix-like system, you can write a shell script to wrap bin/esp32ulp-elf-nm and handle the redirection into a file. I'm trying to make a python wrapper for the ulp code, thanks, this gave me the idea to use python. Since Arduino for esp32 already depends on Python, this...
