🚀 New Practical Guide: Connecting & Configuring an SPI TFT Screen on the OK3568 Platform
We’ve released a complete, engineer-friendly tutorial showing how to integrate the ST7735S 1.8" SPI LCD with the Forlinx OK3568 embedded platform — from wiring, device-tree configuration, kernel driver updates, to user-space framebuffer testing.
🔧 What’s inside:
• Accurate hardware pin-mapping (SPI + GPIO + BL)
• Device Tree patch for enabling spi0 with ST7735R driver
• Kernel FB_TFT driver activation + optimized init sequence
• Pixel offset handling, gamma tuning & rotation support
• A simple test app to verify framebuffer output
This solution enables a cost-effective, lightweight display interface for industrial control, portable terminals, and edge devices — and provides a solid base for future add-ons like touch or backlight control.
👉 If you need the patch or engineering support, feel free to reach out!
