LiquidCrystal Library - Nyob Zoo Ntiaj Teb

Qhia pom kev siv 16x2 LCD zaub. Lub tsev qiv ntawv LiquidCrystal ua haujlwm nrog txhua lub LCD qhia uas tau sib xws nrog Hitachi HD44780 tus tsav tsheb. Muaj ntau ntawm lawv nyob ntawd, thiab koj tuaj yeem feem ntau qhia lawv los ntawm 16-pin interface.

Daim duab no luam tawm "Nyob Zoo Ntiaj Teb!" rau lub LCD thiab qhia lub sijhawm.

Lub Circuit Court: * LCD RS pin rau digital pin 12 * LCD Enable pin to digital pin 11 * LCD D4 pin to digital pin 5 * LCD D5 pin to digital pin 4 * LCD D6 pin to digital pin 3 * LCD D7 pin to digital pin 2 * LCD R/W tus pin rau hauv av * LCD VSS tus pin rau hauv av * LCD VCC tus pin rau 5V * 10K resistor: * xaus rau +5V thiab hauv av * wiper rau LCD VO tus pin (tus pin 3)

Lub tsev qiv ntawv tau ntxiv 18 Plaub Hlis 2008 los ntawm David A. Mellis lub tsev qiv ntawv hloov kho 5 Lub Xya Hli 2009 los ntawm Limor Fried (https://www.ladyada.net) piv txwv ntxiv 9 Lub Xya Hli 2009 los ntawm Tom Igoe hloov kho 22 Kaum Ib Hlis 2010 los ntawm Tom Igoe

Tus lej piv txwv no nyob hauv zej tsoom.
