Re: Pico W not working, even though it was

The default frequency is 400000. I2C is designed for short wires, like 30cm. If you use longer wires, you have either to lower the frequency, which you did, or use pull -up resistors with a smaller value, e.g 470 ohm instead of 4700 ohm. There are special transceiver chips which you could use, but t...

Re: led flash 10 times, not 5?

Looks like a Thonny thing, executing boot.py twice, once in raw mode for the board set-up magic it does and once for the regular boot.
So a good rule, if something strange happens is go back to barre bone and kick out any "helpful" tools.

Re: BMP280 / BME280 uPython

Looking at roberthh's page, am i to rename and use either bme280_float.py or bme280_int.py to be just bme280.py depending on the one i want to use, and then put that on the pico w alongside bmetest.py and use that as the top level working example for my editing purposes? Yes, you can do that. The d...

Re: ESP UART lacks deinit method, but documentation states it exists?

It seems that uart.deinit() exists for most ports except ESP8266. Maybe because the one UART of the ESP8266 is used for REPL. What did you want to achieve using uart.deinit()? P.S: There is a discplaimer somewhere at the beginning of the documentation that not all documented properties apply to all ...

Re: ESP-01 vs ESP-01S LED Flashing Issue

Try to work with Putty first. Putty#s flow control setting must be 'None'. The garbage at boot is normal, since the ESP8266 firmware starts with 74600 baud and switches later to 115200 baud. The ESP01 flash size must match the firmware. The standard firmware requires at least 2 MB flash. If your dev...

Re: Implementing network support for the RP2040 and an ESP8266

With the RP2040, you can use any ESP32 module like a low cost generic one as WIFI/Bluetooth adapter using the NINA-W10 firmware for the ESP32 and the Arduino-Nano connect firmware for the RP2040.

Re: For pico port ntptime not standard?

Do not enable it in mpconfigport.h or disable it deliberately with:

#define MICROPY_PY_FRAMEBUF (0)

in mpconfigport.h. It helps after major changes to the configuration to run

make clean

before starting a new build.

Re: For pico port ntptime not standard?

Onewire is a two step configuration, since it uses a _onewire module, configured in/out per mpconfigxx.h files, and python drivers per manifest.py. For included python files, look also into the port's modules directory, because the usual manifest,py will include all scripts in that directory, for be...
