Does not build for esp8266

[larsks]

The current circuitpython master (9e8d182fe14c05b3e7c6a74e35987ec293310c7a) does not build for esp8266. The build fails with:

../../py/objfun.c: In function 'fun_asm_call':
../../py/objfun.c:549:5: error: passing argument 2 of 'mp_arg_check_num' makes pointer from integer without a cast [-Werror]

We've stopped supporting the ESP8266 in 4.0.0. That's why it's not building any longer.

[dhalbert]

We've dropped support due to ESP8266 not having native USB. We have written a library to support ESP8266 and ESP32 as a co-processor: https://github.com/adafruit/Adafruit_CircuitPython_ESP_ATcontrol and will be adding better support in the future (including hardware in this configuration). Also see https://github.com/adafruit/Adafruit_CircuitPython_miniesptool

Oh, sadness! Thanks for the response.

@dhalbert lets remove the makefile?

[dhalbert]

@ladyada Maybe we'll have the Makefile print a deprecation warning. We haven't removed the Makefiles or source trees for other boards that we never supported - they just live on, which makes it easier to do merges from upstream.

[larsks]

@ladyada or do something like that ^^^^

[ladyada]

whatever you like!

A year ago, I was only a mouse click away from buying 28 Huzzah for my class. Luckily I waited and bought the first six nrf52840 Express now. ;) But sad for all esp owners, thats sure. I'm happy that you gave those boards a second chance. The manufacturers of Octopus boards work around the corner. They are already experimenting with circuitpython.

[ladyada]

Don't forget, you can still use Huzzahs with MicroPython! it works really well and MicroPython is doing an excellent job supporting the ESP8266 and ESP32 :)

Yea, I know. One student is still working with these Chips. He builds an RFid door lock for a workshop room and implements it with Micropython and ampy. He told me last week that he got quite familiar with the linux shell. That made me so proud XD
