USB Hi-Res Stereo Audio DAC using STM32F411 / 401 "Black Pill" development board and Texas Instruments PCM5102A / Philips UDA1334ATS DAC modules
A powerful and fully customizable DIY Open Source Arduino Remote Controller (Transmitter and Receiver) powered by BlackPill STM32F411 microcontroller.
A MAX4466 microphone is read by the ADC of the STM32F401 at 16 kHz, timed by TIM2. An ADC interrupt collects 512 sample. The samples go to Hann window and a 512-point FFT, which gives the frequency content. The result is shown as 32 bars on an ILI9341 TFT over SPI and sent to a phone over Bluetooth. 3 buttons and 4 LEDs control and show the status.
Black Pill STM32F411 drivers from scratch. Without HAL or CMSIS.
Compact Black Pill STM32F411-based ARM Cortex-M4 development board offering high performance, USB-C power, and rich peripheral support for advanced embedded applications.

Validated KiCad symbol, footprint and test project for the WeAct Studio Black Pill MiniF4 STM32F411CEU6 V3.0/V3.1, with official STEP geometry traceability.
Emulator of MSX Keyboard subsystem, to develop, make performance tests and measurements on PS/2 to MSX Adatpter. Now implemented the console as a USB device, plus a USB<=>Serial converter.
