Re: How can I protect sensitive information?

It effectively loads your application code to the M5Stack cloud server, supposedly for your programming convenience. How did you expect it to work? If the code editor is in the cloud obviously the code needs to be in the cloud too. Or is the problem that the M5Stack version of MicroPython firmware ...

Re: MicroPython on ESP32 with SPIRAM support

Answering to myself here, yes it seems it does. Thanks to viral nature of GPL my understanding is this makes the whole project effectively GPL licensed.

This would allow users who intend on using your software in a commercial setting, to take appropriate actions: e.g. include the GNU GPL license and publish the GNU GPL affected source code.
Does Loboris port include GPL code somewhere?

Re: ILI9340/ILI9341 TFT Display

I failed to get @tuupola’s version of this driver to work with HW SPI on the standard esp32 port. After a little investigation I discovered that hw spi crashes due to the driver generating a zero length data block spi write - this is not a problem for the sw version. Can you give a pointer how you ...

Re: I2C slave?

I played around with with esp-idf and created a couple of I2C slaves. They seem to work well. Only problem is though, that since ESP32 has hardware I2C implementation and there is only two I2C busses the slave can only listen at two I2C addresses. I do not know if there is a way around this other th...

I2C slave?

Looking at docs and source it seems ESP32 port does not support I2C slave mode? Pyboard seems to have support. Are there any plans on implementing it in ESP32 port in nearby future?

Re: ILI9340/ILI9341 TFT Display
