TWO-WIRE ETH CLICK on esp32 & Micropython

Closed this issue 4 months ago · 6 comments

Dear Sirs,
My name is Duane Kaufman, and I am working on getting the Mikroe TWO-WIRE ETH CLICK working over SPI to an ESP32 DevkitC board running Micropython.

Has anyone done something like this before, and if so, can you share insights (and code!)?

Sincerely,
Duane

Dear Duane,
unfortunately we did not port the corresponding library to ESP32 nor to Micropython. And there is also no plan to do so..

Never the less, if you need debugging support from our side, let us know.

Best regards,
Thorsten

No problem at all, I appreciate what's been done already! I plan on starting out using ESP-IDF and FreeRTOS - are any of the examples already put together close to a FreeRTOS implementation? Again, thanks for all your effort. Sincerely, Duane

Dear Duane,

yes, we have a project with our Harmony implementation using FreeRTOS. But there are no changes needed for TC6 library. Just make sure to protect the library from be entered from different RTOS-tasks (using Semaphores).
tcpip_iperf_lan865x

If you are going to port the code to Python, it might be easier for you to start with a synchronous (blocking) approach. I made an own branch therefor:
sync-branch

Sincery,
Thorsten

Good to know/review, thanks.

Well, specifically MicroPython ( [ https://micropython.org/ | https://micropython.org/ ] ), which already has a couple SPI-based Ethernet chips incorporated. I may try a pure-Python version first, to get acquainted with the details, patterned after the Adafruit WizNet5k work: [ https://github.com/adafruit/Adafruit_CircuitPython_Wiznet5k | https://github.com/adafruit/Adafruit_CircuitPython_Wiznet5k ] Thanks again, Duane

Dear Thorsten, I appreciate your help. I was wondering, does this library (or, more fundamentally, the LAN8651 chip) support topology discovery?
