Re: Flashing micropython on Wemos D1 Mini Pro

When I saw you post first in the discussion forum, I tried to build & load the ESP8266 firmware for a Wemos D1 mini. It worked as expected. Are you sure that you flashed the firmware with the right flash mode setting? Maybe you need a setting different from the default.

Re: Micropython on ESP32-C3

The version with USB shoudl be the right one: https://micropython.org/download/esp32c3-usb/ Please try to connect to the board using a simple serial terminal emulator like PuTTY or screen or the like. Thonny is not always working. Note: This site will be discontinued. Plwease post question now at th...

Re: No boot.py unable to create python files

Try to use mpremote instead of rshell.

Re: Driver for ENC28J60 Ethernet chip

You could look at the W5500_EVB_PICO config.

Re: Pico W Micro Python for SHT30 Temp/Humidity HELP!

You can measure the existing pull-up resistors between a data line and Vcc, if the sensor is not powered. And you can always connect additional resistors fomr SDA to Vcc and SCL to Vcc. They would be simply in parallel to the existing resistor. Let's assume, the existing value is 4700, and you add 3...

Re: Pico W Micro Python for SHT30 Temp/Humidity HELP!

How long is the wire between the board and the sensor? I2C is designed for short wires, like < 30 cm. Using lower frequencies helps, as well as making the pull-up resistors as small as possible. For rp2 Pico, 330 Ohm should be fine, resulting in ~10mA sunk.
And what kind of error message do you get.

Just remove them. They are not needed any more.

Re: Pico W Micro Python for SHT30 Temp/Humidity HELP!

Semicocolon separates multiple Python statement on a singel line. A semicolon at the end of a line is simply ignored. crc ^= b is the short form of crc = crc ^ b These short forms are allowed for all standard operators like + - * / & | ^ This line is part of the crc calculation and should be fine.

Re: machine.RTC().datetime() gives incorrect hours, minutes, and day of the week

Thanks for the hint. Something is wrong. Either the argument order or the comment in the example. Interestingly, when we read that as the time being set to 12:48:00, the day-of-week number is 2, which is right. The epoch is defined per port, depending on theRTC hardware. So with other ports it could...
