塊tft係taoBAO買??

我一直都買塊黎整dso
不過又怕舞佢唔掂.....

你應該舞得佢掂!不過至少要用STM32否則速度不夠

睇完片, 8051 推呢塊TFT 真係好吃力.
但係反而增加我對CONTROL 呢塊TFT 的信心.
因為咁慢的8051 都推到, 冇理由其他MCU 推唔到的haha.

DSO should stand for "Digital Storage Oscilloscope"

    應該係正解

其實dso又唔一定要tft
我見過網上有KIT用緊atmega64
Sampling rate去到5M/s (當然要用external adc)

除非你dual trace.. triple trace 要唔同顏色

師兄, 請問塊MCU主控板係邊度買?  另外, 塊2.4" TFT module幾錢?

之前見到FAE demo用PIC24推QVGA 320x240 TFT, GUI 好流暢. 塊TFT都係跟樓主一樣用ILI9325 chipset.

ILI9325最好用16-bit interface, 你用既8-bit interface會慢好多. PIC24 natively support PMP (Parallel Master Port), 原生支援16-bit并口, 簡單易用, 比起STM32上的FSMC好用, 再加上Microchip已經有GUI Library.

若果要再快的(e.g. play video), 就非用RGB interface不可.

因為成本關係, Digital Photo Frame唔會用咁多粒IC, 通常一粒SoC 包哂MPU, Codec, Display Controller.

我以前都玩過呢隻,但atmega64都不及我後期的STM32的好用

後期轉左Nano DSO 行TFT + STM32用MP4 殼 build-in 鋰電很方便
