Re: ESP01 MicroPython install

@Roberthh: Sorry, but I don't agree. For the sake of sustainability and for the "Micro" in MicroPython I would (and will) continue to invest efforts in ESP-01 (even if the 512k version may get deprecated - I still have tons, well, tens of them in the field). Easy feature (and size) configurability w...

Re: How to get free space of internal file system?

Maybe this could be a starting point: https://github.com/micropython/micropython/blob/master/esp8266/modules/flashbdev.py#L5-L7 And I guess you'll also need to walk through directories and count uos.stat('from_all_files')[6] in oder to subtract the result from something. Please be so kind and publis...

Re: ESP32 module has released

I guess there's already "somewhat" porting work done (and surely actively in progress) behind the scenes. The guys from Pycom with their LoPy (ESP-32 inside) surely can't be sleeping if they want to roll out in the next weeks.

Re: New chip ESP8285

... perhaps you have two extra pins? And perhaps one of them is the RX of the second UART? Sorry for ignorance. I think I've got your question now (not so familiar with ESP-12 specialities ... more into ESP-01 use cases). GPIO9 and GPIO10 seem to be free and unbound - e.g. I set them to a defined s...

Re: New chip ESP8285 (running MicroPython)

Now someone will have to find out why initial setup is naggy My fault. After doing $ esptool.py --port /dev/ttyUSB0 erase_flash and reflashing firmware everything is working fine. P.S. If I recall correctly, erasing flash before first firmware deployment threw an error ... exotic preconfigured baud...

Re: New chip ESP8285

I wonder how many pins you can use as GPIOs, considering it uses a dual-channel SPI for communication with flash -- perhaps you have two extra pins? And perhaps one of them is the RX of the second UART? Here we have the Pin numbering table of the board: # FKT DESCR -- ---- --------------------- 1 A...

Re: New chip ESP8285 (running MicroPython)

Well, getting MicroPython to run on the ESP8285 (here the PSF-A85 ITEAD board) took about half an hour. Here's a procedure: 1. Prepare the board for flashing MicroPython Wiring: connect PIN3 (EN = Enable) to PIN23 (3V3) PIN12 (GND) to GND PIN15 (GPIO11 SPI_CS0) to GND PIN16 (GOIO6 SPI_CLK) to PIN24 ...
