Re: Why the file I created is not created?

One note ahead: Managing files both on the device and form the PC using e.g. explorer turned out to be a reliable way to corrupt teh files system on your pyboard. That's wha for instance Adafruit decided to make the access exclusive. If PC file access is enabled, any board-local changes are suppres...

Re: Nucleo stm32 F429ZI MQTT

So it is possible. But small modification of utelnetserver.py is necessary. Last lines need to be changed from WiFi to LAN. From this: for i in (network.AP_IF, network.STA_IF): wlan = network.WLAN(i) if wlan.active(): print("Telnet server started on {}:{}".format(wlan.ifconfig()[0], port)) to this:...

Ha Ha Ha. I am certainly finding it hard to resist the urge to buy 1 and have a play with it, as it looks super interesting and RPi is usually very well supported fro beginners.
I succumbed. Placed the order already. Looking forward to playing with it.

Re: RPi makes ther own Mico controller

... it's where I first saw links to the (beautiful!) datasheet . Chapter 3 covers the PIO in-depth. The person who wrote the I2C section 3.6.7 in the PIO chapter says the following: I2C is an ubiquitous serial bus first described in the Dead Sea Scrolls, and later used by Philips Semiconductor. :D

Re: DHT Library for ESP

Now I understand. It looks like you want a driver written completely in micropython. Maybe one exists but I'm guessing that probably not since the C built in driver already exists. Maybe someone has written it in python as purely an academic exercise.

[NUCLEO/STM32F429ZI] How to flash and how to access the REPL

I just got the STM32F429ZI NUCLEO board. I have been using ESP32s with micropython but this is the first time I'm using a Nucleo board and the STM32 system. This is a sort of guide for idiots like me to get started with this board and possibly others like this. 1. Download the micropython firmware: ...

Re: Port Expander PCA9554

In your file pca9554.py I see the following typo:

Code: Select all

from maschine import I2C
Not sure if that is causing the issues.
