Looking to buy a little microcontroller board, which I haven't done since like 2012. I thought everyone was cloning #arduino but those days are over and the only super cheap one I can find is a Pro Micro knockoff (not a regular Micro) and I want more pins...

Okay I'm so incredibly excited to show this :bowsette_redhead_angry: The CNC machine is almost ready and here is a short video of the z axis at work, together with a 3d printed pen holding contraption (courtesy of my friend who kindly printed it for me 🥰)
I can't believe it works. Now all that remains is the software part 👀

Is there anyone in the room with knowledge about #ESP32 microcontrollers?

I am playing with a #Waveshare development board that has an #AMOLED and a touchscreen, and it says it has built-in #SH8601 display driver and #FT3168 capacitive touch chip, using #QSPI and #I2C communication respectively.

It directly works in #Arduino with #C, but I am trying to make it work with #MicroPython.

Before I spend effort trying to compile it with #LVGL, I want to know if I could print a "Hello World" to the screen as is, and while my mind tells me that I need a driver, the sentence "built-in display driver using QSPI" makes me think that I could eventually use the display without code drivers, but I don't know how.

I'd love to see an example, if it's possible, or to be pointed to any resources that I can read in this regard. I am complete newbie.

Re-posts are appreciated.

Thank in advance 😊

I am still in the "what time is it?" rabbit hole.

I now have a working bus mux, after having to get a new one - Don't ask, it wasn't me 😠

Anyway, with 4 types of 0x68 I2C RTC's connected to my , but I needed a definitive time source so that I can comparatively measure drift.

Enter a -6M module. Finally have code working to read the time & date from it. Usually strtok() is my goto, but it skips empty fields. Got something working with strchr() instead.

Publishing soon...
