Je fourni cette bibliothèque à vos risques et périls !
SAINSMART ARDUINO MEGA PINOUT WITH FANS ZIP
J’ai fait cette adaptation dans le fichier zip ci-joint.Ĭette version fonctionne avec Arduino 103 et l’afficheur SaintSmart LCD20x04 sur VISTA PRO. Il faut donc adapter la biblothèque fournie par SaintSmart aux versions Arduino >= 100. La biblothèque LiquidCrystal_V1.2.1.zip ne peut pas piloter LCD20x4 de SaintSmart car le brochage de l’afficheur sur le composant I2C est différent !! La bibliothèque fournie par SaintSmart ( LiquidCrystal_I2C.rar) ne fonctionne qu’avec la version Arduino 023 !!!Īussi pour vérifier votre afficheur charger Arduino 023.
I provided the library with your own risk! This version works with Arduino 103 and the display SaintSmart LCD20x04 in VISTA PRO.

I made this adaptation in the zip file attached. It is therefore necessary to adapt the library provided by SaintSmart Arduino versions> = 100. The library LiquidCrystal_V1.2.1.zip can not control LCD20x4 SaintSmart because of the pinout of the display on the I2C component is different! The library provided by SaintSmart (LiquidCrystal_I2C.rar) version only works with Arduino 023 !!!Īlso check your display load Arduino 023. Do a little animation by writing to the same location Lcd.setCursor(0,3) // character 0 on line 3 (4th line) Lcd.setCursor(0,2) // character 0 on line 2 (3rd line) Lcd.setCursor(0,1) // character 0 on line 1 (2nd line) Lcd.home () // go home to character 0 on line 0 (1st line) Lcd.createChar ( i, (uint8_t *)charBitmap ) Lcd.setBacklight(1) // switch on the backlightįor ( int i = 0 i < charBitmapSize i++ ) Int charBitmapSize = (sizeof(charBitmap ) / sizeof (charBitmap))
LiquidCrystal_I2C lcd(lcdAdrr) // I2C addr #define lcdAddr 0x3F // set the address of the I2C device the LCD is connected to Report back whether this has you up and running. Once you’ve done all the above then use the sketch below and compile + upload. I would guess the LCD module has a resistor anyway, so if the display backlight is dim then you can probably remove this resistor afterwwards and wire Vcc directly to +5V The resistor is there to protect the LED backlight. The replace 0x3F against lcdAddrin the example below with the address you find.Ĭonnect as follows LCD Backpack > Arduino

Try the code below, but if it doesn’t work with the 0x3F address then try running the I2C Scanner sketch from the Arduino Playground, and it will report the addresses it finds. The Sainsmart example code seems to suggest that their I2C backpack is wired in the ‘standard’ way for the I2C library, but there is an obvious mistake in the page telling you that the interface is on 0x3F, but the example code is for 0x27.
Don’t just rename them, you have to remove them from the ‘libraries’ folder completely or there will be a conflict. Make sure you remove the existing standard LiquidCrystal and LiquidCrystal_I2C libraries.
SAINSMART ARDUINO MEGA PINOUT WITH FANS INSTALL
First off, I’d recommend you download and install the New Liquid Crystal Library, to replace the default one that comes with your IDE installation.
