Re: MicroPython on ESP32 with SPIRAM support

@loboris [*There is no remaining GPL licensed code in the repository as of now. Fixed GPIO initialization after deepsleep if ext0 or ext1 wake up source was used GPIO s used as ext0 or ext1 wake up sources are now functional as digital IO pins after deepsleep I2C module Wiki page added. That is all ...

Re: MicroPython on ESP32 with SPIRAM support

It is great to see the many conversations in this single thread! However, I am starting to wonder if it were not better for Loboris MicroPython to have its very own subsection in this forum. This would provide an overview to the many subtopics. For example, currently I have some useful information t...

Re: MicroPython on ESP32 with SPIRAM support

I'm sorry the documentation is not clear about this. I'll update it as soon as possible. Thank you for the additional deepsleep information, Boris. The M5Stack goes into deepsleep now and is awakened by either of two buttons I defined. rtc = machine.RTC() rtc.wake_on_ext0(Pin(38), 0) rtc.wake_on_ex...

Re: MicroPython on ESP32 with SPIRAM support

I would like to deepsleep an M5Stack and wake it on button B or C press. I am even not sure whether this is possible. Here is what I tried: import machine from machine import Pin rtc = machine.RTC() rtc.wake_on_ext0(Pin(38), 0) rtc.wake_on_ext1(Pin(39), 0) With this, I get the following error: TypeE...

Re: MicroPython on ESP32 with SPIRAM support

Thanks loboris for your hard work!
Looking forward to the new I2C documentation, concerning software I2C on non-standard GPIO pins.

Re: MicroPython on ESP32 with SPIRAM support

You can use i2c = I2C( -1 , scl=scl_pin, sda=sda_pin) , the hw I2C 0 will be selected. Is this already available in the prebuilt firmware? Currently, any attempt to drive a Heltec SSD1306 OLED with the required software I2C fails with: OSError: I2C bus not available EDIT I guess not yet, since the ...

In any case I don't want to hijack this thread so I open another one for discussion related to my project.
Thanks tuupola!
For those following this trail, here is the new M5Stack thread.

Re: ILI9340/ILI9341 TFT Display

@rcolistete But I prefer to use Loboris MicroPython for ESP32, configured with : https://github.com/tuupola/micropython-m5stack Thanks, tuupola ! Thanks for the tip. I will definitely try that out. I had seen tuupola's repository before, but had thought is was some sort of placeholder for a future p...

Re: ILI9340/ILI9341 TFT Display

@jeffm I am now playing with the @loboris port which has a fast driver and permits both telnet and ftp. The M5Stack official firmware, which is based on the loboris version does not have telnet enabled. How did you achieve this feat? My M5 keeps on rebooting with every attempt to employ the esptool ...

Re: Some problems with asyn library

@jonaslorander I very well know Peter's excellent uasyncio tutorial. It is just that I wanted to coerce @pfalcon into writing something about uasyncio on the official Pyboard documentation pages ; nothing else. Today, I ran into the infamous umqtt hang problem . Peter again developed a workaround th...
