Excellent! Can you also prevent incoming Ctrl-C from stopping the interpreter? Receiving binary data is impossible without it.

I made a crude hack to do this, but an official way would be nice.

Re: Making sounds

If there was an I2S module for Micro Python, you could play short samples from RAM, similar to what this project does: https://github.com/espressif/ESP8266_MP3_DECODER

It re-purposes the I2S data output as a 5-bit PWM output, on pin GPIO3/RX0, or uses a real I2S DAC.

Re: Docker image

This is great! Thank you. Based on instructions on Stack Overflow , installation was easy on a Mac with Homebrew : $ brew cask install dockertoolbox ... $ docker-machine create --driver "virtualbox" Docker ... $ docker-machine start Docker ... $ eval $(docker-machine env Docker) $ mkdir ~/Desktop/ES...

Re: How to access pins on AI-Cloud Inside (black) boards?

Hi! I also use the ESP-01, with the early access v04 firmware. It works fine for me. (... as long as you have at least 1 MB of external Flash on it. 512 kB variant not tested.) GPIO pins 1 and 3 are the UART pins, which are normally used for the REPL. That's why they cause the REPL to hang, if you c...

Re: Using the tx/rx pins not for UART

Hear hear! Except, I would like to use the UART pins as UART pins, but without the REPL. I'm going to connect an ESP-01 module to a serial camera module . Problem right now is, there are Control-C characters (0x03) in the binary data returned by the module. This is interpreted as a KeyboardInterrupt...

Re: Early access releases #3 & #4

Hi! Some observations about v04 and also webrepl. - Reading the RTC memory caused the firmware to crash at first: import machine machine.RTC().memory() Then, after writing something (RTC().memory("ABC")), it does not crash anymore. - Deep-sleep using the esp module function does not seem to work wit...

Re: New mp-esp8266-firmware-v01.bin on ESP8266

Hi, Damien. I programmed a cheap ESP-01 module from MCM with the binary you sent. It works great! A question: It seems that MicroPython stores the ESSID and password somewhere, so that the module can reconnect after a reset. Is there a way to erase this information, so that I don't leak the network ...
