Community Service Award for Damien George

I just stumbled upon this: http://pyfound.blogspot.ch/2016/03/genuinely-nice-chap-damien-george.html Congratulations, this is really well deserved! We are all really grateful for all the work going into Micropython in general, and the work on the Micro:bit port in particular is going to bring us a w...

Re: esp8266 UART0 communicate with other UART device

No need to modify it. You can just use prints in your program to send text to the device.

Re: ssd1306 using I2C on the esp8266

Found it https://github.com/micropython/micropython/issues/573

But I remembered wrong and it's not actually what would help you here.

Re: i2c multi-byte read for ESP8266? (e.g. RTC1307)

There is an additional flag you can pass to readfrom and writeto to make it not end the transmission. You can use that to implement mem_read and mem_write, I think.

Re: ssd1306 using I2C on the esp8266

Hmm, on Arduino you would force data like this to live in the program memory, on the flash, by using PROGMEM. I vaguely remember there was some discussion about doing something similar in Micropython, but I can't find it now on the forum.

Redirect REPL to a socket

I know that we are going to get an awesome websocket-based REPL through a web browser, but in the mean time I'm wondering if it would be possible to do something similar to this example from nodemcu, https://github.com/nodemcu/nodemcu-firmware/blob/master/lua_examples/telnet.lua , where you basicall...

Re: After successful flash no REPL

I think the reason why your USB2TTL is disappearing from the device list is simple -- the ESP8266 requires about 300mA of current, and that's more than your USB2TTL can provide. Either the computer detects overcurrent, and shuts the port off, or the USB2TTL shuts down by itself, to protect your comp...

Re: Corrupted filesystem

Yes, I used the -m8 option, and also tried the -m32 option, without any improvement. I desoldered the board and replaced with a different one, with the same result. Then I tried the desoldered board directly. They all have the same problem. I also noticed, that they restart at random even when not d...

Corrupted filesystem

I have tried both the v1 and v2 version of the alpha firmware successfully on many boards, but I'm having a hard time with this one. It's an ESP-12 module which I have already soldered onto a printed circuit board for my robot. I originally programmed it with the Arduino IDE, but now I wanted to try...

Re: New mp-esp8266-firmware-vXY.bin on ESP8266

There is a very cool library for ESP8266 that uses its I2S hardware, with DMA, for driving neopixels. It doesn't let you choose the pins freely, but it's blazing fast: https://github.com/cnlohr/esp8266ws2812i2s
