HUB75 Driver Development for LED Panels
Brief description:
- We developed a complete wearable solution that seamlessly embeds electronics into a T-shirt, transforming it into a powerful health monitoring device. Using specialized conductive materials, we integrated sensors, a power supply, and a data bus directly into the textile—ensuring unobtrusive, comfortable wear while maintaining robust connectivity.
HUB75 Driver Development for LED Panels
GPIO Push-Pull Driver
- A straightforward approach using general-purpose I/O pins to manage signals for the HUB75 interface.
Timer-Driven PWM
- This method uses on-chip timers to generate accurate and efficient PWM signals, driving the LED panels with precise brightness control.
I2S-Based Driver
- An innovative technique repurposing the I2S audio peripheral—commonly used for sound—to transmit the pixel data required by the HUB75 LED interface.
Our solution was successfully ported to three popular microcontroller families—STM32F, NXP, and Renesas—demonstrating wide compatibility and versatility. This cross-platform capability ensures flexibility for a broad range of embedded applications that require robust and efficient LED panel control.
