Can I read enviromenz variables?

Hi,
I would need to figure out the user's home directory on the unix port. So... I could try to find out what $HOME corresponds to. Can this be done in micropython?

Re: Custom build works, except i2c.readfrom_mem

Just wanted to say: "thank you!" This was very helpful to me, because I stumbled over the same problem.
Did you raise an issue at the espidf github repository?

Re: TTGO T-WATCH-2020

As promised I tried to compile for the TWATCH and I had quite some trouble. Before trying the t-watch I tried the standard lv_micropython and this already did not work. My micropython (without lvgl) is based on the newest esp-idf and this does not seem to work on lv_micropython. Amir Gonnen, the guy...

Re: ESP32-CAM-MB + Development Board CH340G

Many thanks for this workaround.
It did not work on my default thonny version, installed with apt on Ubuntu 20.04, but it did work when I installed the newest thonny version from github.
Excellent! Now I can play with the ESP32.
Did you get the camera driver to work? and if yes, how did you do it?

Re: Issues Compiling ESP32-Cam firmware

Hi, I have no problem in compiling the esp32-cam micropython version. However, I have a problem running the driver (see my recent post) I guess you did not compile "standard micropython" (micropython without the esp32-cam driver) either. This is what I would try first. In order to access idf.py you ...

esp32-cam driver

I am trying to get the esp32-cam driver to work on mp. There is a github repository which explains how to do this: https://github.com/lemariva/micropython-camera-driver When following this with the latest version of mp, I get an error when the driver tries to allocate the frame buffer memory on PSRA...

Re: ESP32-CAM-MB + Development Board CH340G

I have a similar problem. It seems that the Linux serial driver sets RTS and DTR such that you are always in programming mode. I tried to run gtkterm on which you can individually reset DTR and RTS and if I do this, then I see REPL as expected. It is therefore a problem of the serial driver and not ...

Re: esptool on virtual box

Yes, that works. So the problem is that DTS DTR are not correctly passed from virtual box to the Windows driver. Putting the short for flashing Micropython from time to time is ok for me.
Thanks Robert
