STMF4 Discovery Audio USB

T-UDAC : USB Sound Card with STM32F4 DISCOVERY and T-DAC

The STMF4 Discovery project (Coocox) as USB sound card works.
Please, be excited to create an USB headphone sound card for just USD 15.00
Configured for 24bit, 48KHz - it works also on RPi-DAC

Pico-C STMF4 Discovery USB UART

Pico-C on ARM Cortex-M4 (STM32F4Discovery and XynergyXS FPGA) with USB UART

Use the STMF4Discovery with USB VCP (USB UART Port) and Pico-C command line (shell) to have access to all board registers and features.

Write C-language like scripts in order to test the board or to implement new commands and features.
