These pins are used for the internal flash, they are not available on your board anyway. See here, the pin numbers in micropython are the ESP-8266 ones (e.g. GPIO5) which are not the ones printed on your board.

That would be awesome! It seems that one issue is the sector size: The onboard flash has 4 kiB sectors while the sd card uses 512 byte ones. Unfortunately creating the FATFS filesystem struct always allocates the maximum sector size, so it runs out of memory... Edit: Actually there seems to be enoug...

The esp8266 port doesn't have the pyb.mount function which is used in sdtest.py (I think it should be in os now, but its not there either). os.Vfsfat seem to be imported from extmod/vfsfat while the other file system functions (e.g. os.mkdir,...) just call the methods of the first file system object.

I would like to read and write files from an sd card. Currently I'm using a microsd connector ripped from an old device (connected to a custom esp-12 breakout board) but the goal is to mount a connector on a new custom pcb eventually. I have gotten sdcard.py from micropython/drivers/sdcard to work b...

Unfortunately running any kind of main loop prevents the sleep modes from starting. I first tried using machine.Timer to call my loop function periodically but that doesn't work because you can't do very much in interrupt handlers. So I thought that as the loop function should be the only thing that...

I just set MICROPY_REPL_EVENT_DRIVEN to 1 and my force_modem_sleep function works now! :D The current drops to 15mA including regulator losses (the USB powerbank I was using actually switches off now because it thinks nothing is connected). Is there some reason why MICROPY_REPL_EVENT_DRIVEN 1 is not...

The force sleep API is described in the API guide in chapter 3.7. There is also a general guide about low power modes . I have tried to add a simple function esp.force_modem_sleep STATIC mp_obj_t esp_force_modem_sleep() { wifi_station_disconnect(); wifi_set_opmode(NULL_MODE); //set wifi mode to null...

There seems to be a separate function to actually force the sleep mode to begin, see here: https://github.com/esp8266/Arduino/issues/460 There is more info here: http://bbs.espressif.com/viewtopic.php?t=1134 Someone from Espressif posted this sample there //sleep over. void fpm_wakup_cb_func1(void) ...

I've been trying to reduce the power consumption of my esp-12 with micropython. Currently it uses 80-85mA (through a linear regulator with 20µA quiescent current from ~3.6V) no matter what I do. I have tried using esp.sleep_type() to set either esp.SLEEP_MODEM or esp.SLEEP_LIGHT but the power consum...

I am also interested in disabling the REPL over UART. I would like to use a serial controlled e-Paper display.
