aitendoさんから手に入れた2.4インチ液晶モジュール（TP付き） [M024C9320TP] をarduinoに接続してみる。
使用するのは「3.3V版8MHz動作のArduinoUNO互換機」だ。
https://ameblo.jp/fc2miha/entry-12833772800.html
映像
aitendoさんのページからポイントを拾って行く。
１．動作電源は3.3v
２．タッチコントローラーはXPT2046
３．ディスプレイコントローラーはILI9320
４．パラレル８ビットまたは１６ビットインターフェース
５．ジャンパーJ2をショートすると8ビット、オープンで１６ビット
６．８ビットの場合はD8-D15、１６ビットの場合はD0-D15
７．デフォルトは16ビットモード
８．接続（たぶん８ビットモード時）
液晶側/Arduino UNO側
LED-A/3.3V
VCC/5V
GND/GND
DB8～DB15/D0～D7
RS/A0
WR/A1
CS/A2
RESET/A3
RD/3.3V
上記を踏まえサンプルソースはと探すと、AdafruitからダウンロードしておいたTFT-LCD-Library-masterの中のgraphictestあたりがのソースのコメントが素敵な感じだったので・・・
とりあえず、採用する。
ソースコメント抜粋。
#define LCD_CS A3 // Chip Select goes to Analog 3
#define LCD_CD A2 // Command/Data goes to Analog 2
#define LCD_WR A1 // LCD Write goes to Analog 1
#define LCD_RD A0 // LCD Read goes to Analog 0
#define LCD_RESET A4 // Can alternately just connect to Arduino's reset pin
// When using the BREAKOUT BOARD only, use these 8 data lines to the LCD:
// For the Arduino Uno, Duemilanove, Diecimila, etc.:
// D0 connects to digital pin 8 (Notice these are
// D1 connects to digital pin 9 NOT in order!)
// D2 connects to digital pin 2
// D3 connects to digital pin 3
// D4 connects to digital pin 4
// D5 connects to digital pin 5
// D6 connects to digital pin 6
// D7 connects to digital pin 7
なんか矛盾があるような気がするけなんか素敵な感じ。
とりあえず、半田付け。

１．ピン配置に２列のピンソケットを接続
２．J2をショートさせる

さて、実行！！
むむ、動かない！！英語で知らないチップだと言っているぞ。
ソースを見ると、なんと、ILI9320には対応していないらしい！！
困った。
こんな時は・・・やっぱりgoogle先生に聞いてみた。
じゃーん
http://blog.tkjelectronics.dk/2010/03/arduino-mega-and-ili9320-display/
arduino MEGAにてILI9320に接続しているデモを発見！！
ArduinoUNO用に改造！！
あっさり動いたので記録しておきます。
ありがとうThomas
