Developing an LCD driver under RTOS, are you often confused by FSMC timing and pin configuration? Today, using the STM32 + ILI9341 example, I will guide you step by step from 0 to 1, helping you avoid 90% of the pitfalls! 1. First, understand FSMC and 8080, the ILI9341 supports 8080 parallel timing, and the … Read more
Interactive interfaces are increasingly integrated into various applications, such as medical devices, process control, mobile phones, and other handheld devices. These interfaces are primarily based on graphic HMIs (Human-Machine Interfaces) using color LCDs. The demand for TFT-LCDs has greatly increased worldwide. This article introduces how to use the FSMC (Flexible Static Memory Controller) of the … Read more
