Re: ESP32-cam error( Can't build MicroPython firmware)

Change the name of the esp32-camera-for-micropython to just esp32-camera inside the esp-idf/components folder and try to build it. Edit to add: This version of micropython that the OP is building is from the pycopy fork. I was able to build it with mainline but this required some changes as the form...

Re: How to use usb mass storage in ESP32?

It is still not a 100% clear (to me at least) what exactly you want to do. It looks to me that you want the ESP32 to act as an intermediary between your CNC machine with the serial port and another computer (a PC) which is probably not able to be physically/directly connected to the serial port on t...

Re: ESP32 Camera (ESP32 Cam) Library

I just got a esp32 camera board and this firmware works well. I wonder if the esp-idf exposes more functionality. Many thanks for developing and linking to this.

Re: Network LAN

Hmm..I looked around on the loboris forum and on his Github, but I'm still not entirely sure how much more work/tweaking would have to be done. I am able to do API calls to the methods in the LAN class but once called, they do not seem to work. Definitely some driver related work has to be done rel...

Re: [DS-D6] build for cheap DS-D6 nrf52 fitness tracker

Fanoush, This looks fantastic. Thanks for all your work. I received my watch but have not uploaded any new micropython firmware yet. Prior to doing that, I want to make sure I do the steps correctly by reading through all of your github docs, so I don't brick it ;) Just an (idiotic) question before ...

What happens if you send i2c.writeto(40,b'1')?
This neither sends a single bit nor a 1. It'll send the ascii value for '1' which is 0x31.
@jimmo -- thank you.

Hi rpr,

It uses a LAN8710 chipset, which should be quite similar.
I'll take a look into that and let you know the outcome.

Thank you
Thanks. I'm interested.

Re: Network LAN

If the board uses a lan8720 chipset, the loboris fork for the esp32 has support in micropython. Loboris made some small hardware mods to the lan8720 boards he was using. There is at least a thread on his forum. https://loboris.eu/forum/showthread.php?tid=334 Loboris commented that he thought his cod...
