ALPHA 8F328P-U 如何驅動 2.4寸SPI液晶屏模块 240*320 带触摸TFT ILI9341？

你用Arduino UNO驱动起来。。。用8F328P-U就没问题。。。你先用UNO驱动下试试

但結果出乎預期，用Arduino自帶的庫和範例，在Uno 沒問題，但 8F328P-U 卻不成，初步看到應是8F328P-U的硬件 SPI 的問題。但沒法核實。

===================================================
#include "SPI.h"
#include "Adafruit_GFX.h"
#include "Adafruit_ILI9341.h"

// For the Adafruit shield, these are the default.
#define TFT_DC 9
#define TFT_CS 10
// Use hardware SPI (on Uno, #13, #12, #11) and the above for CS/DC
Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC);
// If using the breakout, change pins as desired
//Adafruit_ILI9341 tft = Adafruit_ILI9341(TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO);
