A few years ago I discussed WS2812-compatible (ws2812, sk6812, pd9823, …) LEDs https://andre.blaatschaap.be/2017/03/led-there-be-light-part-1/ https://andre.blaatschaap.be/2017/07/led-there-be-light-part-2/ https://andre.blaatschaap.be/2017/07/led-there-be-light-part-3/ https://andre.blaatschaap.be/2017/07/led-there-be-light-part-4/ Back in the days, I’ve discussed a few code snippets, but I’ve never came around on releasing the firmware I’ve wrote back in the days. Now I’ve uploaded the old code from back in those days to https://github.com/BlaatSchaapArchive/LEDcontroller. This…
High Level USB Device Library
Hello there! I’ve been working on a High Level USB Device Library. The reason for this is kinda related to the series of posts about the STM32F103 clones I’ve published. The thing is, the STM32Cube* HAL is BSD licensed, but the USB Middleware is SLA044. This means, the HAL can be used on any clone…
32F103 Comparison (part 2)
Update 2020-06-13: Added the HK32, updated stlink-gui/st-flash: it works with CKS32 now. Welcome back to my 32F103 Comparison. Let’s recap. The STM32F103C8T6 is a popular microcontroller by STMicroelectronics. Various Chinese manufacturers are producing parts in the same naming scheme, eg. APM32F103C8T6, BLM32F103C8T6, CS32F103C8T6, GD32F103C8T6 and MM32F103C8T6. What does this mean? There are parts, such as…
32F103 Comparison (part 1)
Update 2020-06-13: During some discussions about STM32F103 clones, I’ve sent some parts to Richi’s Lab who makes die shots of ICs. Links to the die shots for the parts have been added. Furthermore, I’ve added another part, HK32, to the comparison. I have mentioned some websites were unreachable. It turns out, the websites work when…
