Maker PI PICO, een mooi basestation voor de microcontroller Raspberry PI PICO

- 10th March 2023 - devpepo

De microcontroller Raspberry PI PICO is de eerste microcontroller van de Raspberry PI Foundation en bevat tevens een eigen ontwikkeld System-On-Soc, de RP2040. Er is al veel geschreven over deze microcontroller, voor meer details: zie de Getting Started pagina. Er zijn diverse SDK’s (software development kits) waarmee de microcontroller geprogrammeerd kan worden: MicroPython (pdf), CircuitPython,

Microcontroller USB-Serial port op MacOS Big Sur

- 6th April 2021 - devpepo

MacOS Big Sur (macos 11.*) heeft vele veiligheidsaspecten ingebouwd. Vooral op gebied van drivers is het zoeken naar een voor MacOS Big Sur geschikte programmatuur. De Raspberry PI PICO is een microcontroller waarop software te maken is met MicroPython, CircuitPython of C/C++. Ik beperk mezelf tot de eerste twee SDK’s. In eerste instantie is er

WeatherStation: temperature and humidity on OLED display

- 8th January 2018 - devpepo

At last, I’m able to continue with the Weatherstation project. In this case, getting and displaying temperature and humidity from the SHT30 sensor on the OLED display in a first version. Both devices are WeMOS shields, placed up and besides the WeMOS D1 mini. Result on the OLED-display:Hardware considerations. Hardly difficult. The SHT30 shield and

CH340/341 serial-USB driver panic on MacOS 10.13 High Sierra

- 5th January 2018 - devpepo

Have I updated my MacOS from El Capitan (10.11) to High Sierra (10.13) at last, I’ve got a kernel panic when I connect an Arduino Nano to it! Connecting a WeMOS D1 mini, or LOLIN32 Lite, will have same problem. Turns out, its not a hardware problem (pfff), but a driver-problem: the currently installed CH340/341

project Weatherstation: intermezzo -hardware considerations

- 10th March 2023 - devpepo

As written in previous episode, the weatherstation contains WeMOS D1 mini and several mini-shields. Each shield communicates with the ESP8266 via GPIO-pins. Tabel 1 summaries which WeMOS mini pins (D1.. D8) are used by WeMOS shields. I also added some RobotDyn-shields, which I intent to use. Table 1 shields comptability We see the Buzzer shield

Weatherstation built with ESP8266 and MicroPython

- 10th March 2023 - devpepo

I’ll start a series of articles about the making of a weatherstation. A weatherstation is a perfect project for starters, and you can make it as complex as you wanted. For me, it is also a focus to learn MicroPython. My intended audience are those who want to learn MicroPython to control microcontrollers, such as
