ESP-12E boards -> Some fundamental questions
Posted: Wed Jan 11, 2017 9:28 pm
Hi,
I recently got hands on a ESP-12E based board, seemingly produced by doit.am. I flashed it with MicroPython 1.8.6 on Windows. That seemed to have worked; I can connect to the REPL via COM4 and can run python code on it.
I have some major problems with it, which I cannot seem to solve on my own:
1.
Shouldn't there be a way to copy files to the board via USB file transfer? I've read in the pyboard docs that there can be files transfered to the board with the regular windows explorer (as it were a usb flash drive); Is this not the case with the ESP8266 boards?
2.
On macOS, on connecting the board to my computer, I expected that a ttyUSB* device file would show up under `/dev`. That is not happening; Shouldn't it? I have no idea how to connect to it otherwise.
3.
Is there a way to find out which I/O ports are available? I know there are some PINs connected to the esp8266, but I cannot find documentation on the website of the manufacturer.
The boards full name is `ESP12E Devkit V2`, made by doit.am. It looks like this: https://images-na.ssl-images-amazon.com ... L1200_.jpg
Sorry if this is some basic stuff I'm asking, but I'm really new to this esp8266 and MicroPython in general, and I'm having a hard time getting some useful information and documentation (useful for me) on the board. I've read some of the MicroPython docs on the ESP8266. The PINs mentioned in the docs are the names from the ESP8266 CPU, but I have no idea how to find out which PINs on the board (see image above) are connected to which of the ports of the CPU.
I hope someone finds the time to read this :)
