Gemini: a www alternative
So, do think that watching scantily-clad young ladies twerking in their bikinis on OnlyFans is a bunch of bullshit? Concerned that Google, Microsoft and Facebook are becoming the gatekeepers of the internet? Annoyed that most sites have become bloated pieces … Continue reading

Microcontroller API design: separate out concerns
My tip: try to separate out device-specific code from SDK-specific code. By “device”, I mean any physical piece of hardware like a DS3231 real-time clock, or an SSD1306 OLED display. Something that you attach to your mcu (microcontroller). By “SDK” … Continue reading

Is it my imagination, or is the #rp2040 more reliable than the #stm32?
Maybe I’m doing things wrong, but I wonder if people have found the RP2040 to work better than STM32’s? Just some of the peculiarities I’ve noticed: I couldn’t quite get an oled display working with an STM32L432KC, and resorted to … Continue reading

Square-wave and boolean-modulated output using sampling
Abstract Tones of a specified frequency can easily be produced on nearly all mcus (microcontrollers) using pwm (pulse-width modulation). The output is a square wave. This post explores the use of sampling to produce frequency waves. Although this is more … Continue reading

#libopencm3 examples for stm32f411
The examples may work on other STM32 microcontrollers, with modification. Such examples include: a basic blink sketch, timers, exti, newlib integration with uart, spi, dma, i2c, pwm, systick, ssd1306, ds3231. So, quite a wealth of things to choose from. Check … Continue reading

My #rp2040 dev board wish-list
Here’s what I want to see in a dev board: Put the pins closer together (longitudinally, of course) so that the board can be inserted into a standard 40-pin IC socket. Forget castellations. Number the pins on the topside of … Continue reading

A nightmare function to kill you in your sleep in #golang
Clickbait title much? I am not a golang programmer. I’m mostly C/C++. I had played with golang many many years ago. I didn’t like it much at the time. I recently thought about parsing a binary file using golang, but … Continue reading
