STM32G431 Analogue TV Transmitter

8 days ago

The author explores creating an analogue TV transmitter using an STM32G431 microcontroller.
Initial experiments involve generating an RF signal for a CRT TV without traditional inputs.
Utilizes the STM32G431's operational amplifiers and DACs to modulate video signals directly.
Overcomes hardware limitations to output grayscale video at 400x300 pixels via RF.
Challenges in adding FM audio modulation are addressed with creative use of the microcontroller's features.
A custom PCB is designed to improve signal integrity and add functionality like composite video and audio inputs.
The project results in a versatile platform capable of rendering graphics, text, and playing audio.
Source code and examples are provided for others to experiment with the setup.
