Re: Turn WIFI Off On ESP8266 Boards

I did recon that the OP wanted to have the CPU be active and only the WiFi be powered down completely.
Browsing the ESP documentation's I have seen that the ESP can be booted this way by juggling with some registers.

Re: Turn WIFI Off On ESP8266 Boards

Only the interfaces are deactivated. There is no reduction in RF power usage implemented as far as i do understand from the source code.

Re: Pyboard pins???

Basically the Y half is the north side of the board where the USB connector is attached. The X half is the south side where you also find the servo pins in the second and third row, as well as the "south bank" pins not found on the Y (north) half. Regarding the "half boards", one...

Re: Avoid flash wearing by altering behavior originally introduced by Espressif (the inventor of the ESP8266)

Sounds plausible then and does only mean, that two of the three methods do wear flash for my application.

Re: "Flash wearing behaviour"

Does this mean the example doConnect() function performs three writes on each execution? wlan = network.WLAN(network.STA_IF) wlan.active(True) wlan.connect('ssid', 'password') Only two methods are writing to flash (last two lines). If so I'm impressed that some of my devices are still operating pro...

Re: I2C issue

How many pull-up resistors are on your bus? Maybe the pyboard is more tolerant in this regard?

Re: "Flash wearing behaviour"

You could capture the SPI communication to the SPI flash chip using a logic analyzer. I do only own a cheap logic analyzers (logic pirate) which is sadly missing compression and streaming via USB (hoping for Xmas ;) ). So maybe someone else can capture a to be defined test session no the ESP?
