Re: MicroPython on ESP32 with SPIRAM support
How do I add a custom C-module? I added it to SRC_C in components/microphython/component.mk . It compiles, but does not get included in the firmware. Code (with probably more headers than I need): #include <stdio.h> #include <sys/time.h> #include <time.h> #include <string.h> #include "freertos/FreeR...

Re: MicroPython on ESP32 with SPIRAM support
Is there also a ready to use binary i can flash with esp32 tool? atm i'm working only under windows and not that firm with the whole build process. More than you are asking for, but it does include a compiled binary: https://github.com/bboser/IoT49 . The compiled firmware is here: https://github.co...

portmodules.h: No such file or directory
I'm following the tutorial for adding modules (http://micropython-dev-docs.readthedocs.io/en/latest/adding-module.html) and am trying to add "mymodule" to the standard esp32 port (the new rebased one). Compilation fails with portmodules.h: No such file or directory : make Use make V=1 or set BUILD_V...

Re: mpfshell: how to execute a file
I added a run command to rshell at https://github.com/bboser/rshell.

Re: no /flash in standard ESP32 build
I also found that -a is required with the ESP32.
Maybe it would make sense to reduce the default buffer size below 255 and make -a default (in my version it is). Of course better hardware (pyboard) works well with the current defaults.

Re: no /flash in standard ESP32 build
I've made a custom rshell (https://github.com/bboser/rshell) for the ESP32 port (should still work with other hardware, but I have not checked).
Aside from the path issue, I had to reduce the BUFFER_SIZE for file transfers to 255, apparently the maximum the ESP32 port can stomach.

no /flash in standard ESP32 build
Is it possible to configure the ESP32 port to use /flash as root rather than /?
(for compatibility with rshell).

Re: ADC Vref
I see, the internal reference is only and input, it is never applied to the ADC Vref, which is 3.3V. Exactly what I need for ratiometric readout.
2nd Question: Apparently adc.read_timed is blocking? Are interrupts still served?
Thanks!

ADC Vref
Can I set the ADC to use the 3.3V supply (or a voltage supplied on a pin) for Vref on the pyboard in Micropython?
Many thanks,
Bernhard
