Re: Stuck on beginning the install

There are quite a few people like me who have not problem in building the binaries using the provided repositories. Please check if you followed the instructions in the README of esp-idf an micropython literally. From the log of the build here I see, that mpy_tool is called with python3. I agree tha...

Re: Stuck on beginning the install

You have to run make in the micropython/ports/esp32 directory. The proper hash value for the esp-idf is inside Makefile. Yo you can as well open Makefile with an editor or the less command and take it from there.

Re: Detecting Pyboard D and USB connection

The Pin name USB_VBUS exists. If I get it's value when connected to USB, it returns 0, and as well, when not connected to USB On a Pyboard 1.1 it returns 1 when connected to USB, On PYBD, there are also names as USB_DP, USB_DM, USB_HS_DM and USB_HS_DP. The latter returns always 1, whether connected ...

Re: Wemos D1 Mini 4MB file read: OSError: [Errno 13] EACCES

You have to open the file for both reading an writing, like: f.open("file.txt", "w+") and before reading, you have to go back to start, like with: f.seek(0) These are standard file operation properties, nothing special to MicroPython. And yes, don't forget to close the file with: f.close() Otherwise...

Re: Integrating Loboris port back to official uP ESP32 port

The esp32 is a reasonable board for dealing a little bit with external sensors, displays and doing WiFi/Bluetooth communication. And at the prices called fro them you can buy two or three to get one which works reliably. It fails badly at everything needing e.g. precision timing, fast ISR, good ADC/...

Re: cannot disable unwanted modules

You have to change the setting in Makefile to:

Code: Select all

MICROPY_PY_BTREE ?= 1
to make the setting in GNUmakefile effective. But in that case you can as well have the change in Makefile itself.

Re: Integrating Loboris port back to official uP ESP32 port

PYBD: With USB & WiFi @120MHz about 28 mA PYBD: With USB & WiFi @216MHz about 50 mA ESP32: With USB/UART Bridge & WIFI @240MHz: about 50 mA but the PYBD feels much more responsive, even at 120 MHz. And the runtest.py script that circulated recently runs faster on a PYBD, even at 120 MHz, but surpris...

Re: Building

It's not that urgent. The board works well so far. Only @devnull needs a new firmware.
