71歳の挑戦... 4"TFT-LCD(NT35510,800x480,16bitパラレル接続)をPico2で動かしてみた

Posted at

　前回に続き、Pico2の動作確認を兼ねて16ビットパラレル接続の4インチディスプレイモジュールを動作させてみました。

Pico2 との接続は次のようになります。

TFT_D0 0
TFT_D1 1
TFT_D2 2
TFT_D3 3
TFT_D4 4
TFT_D5 5
TFT_D6 6

普通に Arduino_GFX_Library で動かした結果、1ループに要する時間が「840msecs」ほどでした。試してから少し時間が経っており記憶が定かではありませんが、メモを参考にすると他のマイコンボードとの比較は次のようです。

ボード 1ループに要した時間（ミリ秒）
Pico (133MHz) 1510msec
ESP32ｰS3 (240MHz) 830Msecs
Pico2 (150MHz) 844Msecs

Pico2 はかなり優秀であることがわかります。Arduino IDE 2.3.4 でのスケッチを以下に示します。
