More DC2N5-LC development for the Black Pill

Over the weekend I finished porting all DC2N5-LC drivers from the Blue Pill to the Black Pill. In particular I was missing the key handling driver, which is now in good working order. I think I might actually port the … Continue reading

Emulated nixie tube clock

I always wanted to make myself a nixie tube clock, but the cost of the tubes, the availability of specialized drivers, and the voltage involved have put me off when I was going to shop for components. Therefore, I came … Continue reading

DC2N5-LC PCB modified for use with a Black Pill

Having finished most of the work around porting the DC2N5-LC firmware to an STM32F411 Black Pill, I thought to adapt its PCB design to use either the STM32F401/STM32F411 version of the Black Pill. At around 3 GBP cheaper than an … Continue reading

Development board for Retroverse

I finally got some time to power up the development board I plan to use to develop Retroverse: It’s based on an STM32H7 MCU that can be pushed to 480 MHz. Porting DC2N functionality to it should be simple enough, … Continue reading

Tape handling driver for Black Pill ready

The porting of my tape handling driver to the Black Pill is done! The Black Pill is now dumping tapes and playing back TAP files (version 0, 1, and 2) too 🙂 Being the Blue Pill plagued with so many fakes … Continue reading

Moving away from HAL in my STM32CubeMX projects

This evening I found out that almost all peripheral driver initializations can be generated by STM32CubeMX using LL alone instead of HAL, which means I can easily get rid of HAL completely in my STM32F103 project! Not so fast though. … Continue reading

Benchmark testing for my USB serial code

Today after work I was able to quickly put together the test code I needed to measure the transfer speed of my “stdio redirection to USB” implementation for the STM32F411 board I am developing with. I haven’t got a baseline … Continue reading

Moving development for Retroverse to a Black Pill board (STM32F411)

I was able to port a few of the drivers from a STM32CubeMX project for STM32F103 to one for STM32F411, which is the MCU used in the Black Pill board I recently acquired. The port of the display and SD … Continue reading

Update on the tape handling driver for Retroverse

Over the last couple of days I was able to finish bits of porting of the tape handling driver to an STM32CubeMX project for Retroverse. The dumping part was tested in conjunction with my C2NEmu hardware and the tape playback … Continue reading

Tape handling driver for Retroverse

I haven’t had a great day today, having slept very little last night, but I started looking into the porting of DC2N5-LC’s tape dumping routine to an STM32CubeMX project, for being used with Retroverse. Stay tuned for more!
