bonjour j'aimerais utiliser un afficheur de 480x272 avec shield CTE TFT LCD/SD.
le contrôleur du display est un SSD1963_480 qui fonctionne très bien avec Arduino Mega.
Mais impossible de le faire fonctionner sur Due.
Pour ce qui concerne la SD carte celle-ci fonctionne.
version du programme arduino 1.8.5
avez-vous une idée??
bien à vous
sur le shield CTE plusieurs pontages possibles.
les pontages marqués par "*" sont réalisés.
LCD VCC
JP1 5V
*JP2 3V3
LCD LEDA+
JP3 5V
*JP4 3V3
JP5 PWM (9)
SPI FLASH
JP6 SPI SS (52)
JP7 SPI SS (10)
SD CARD
*JP8 SPI SS (53)
*JP9 je ne me rapelle plus à quoi cela correspond
JP10 je ne me rapelle plus à quoi cela correspond
et mon code est :
/*
*
* CTE TFT LCD/SD Shield for Arduino Due
*
* Uncomment the following line if you are using this shield
*/
#define CTE_DUE_SHIELD 1
// For this shield: RS=25, WR=26, CS=27, RST=28
/* SD card test
This example shows how use the utility libraries on which the'
SD library is based in order to get info about your SD card.
Very useful for testing a card when you're not sure whether its working or not.
The circuit:
* SD card attached to SPI bus as follows:
** UNO: MOSI - pin 11, MISO - pin 12, CLK - pin 13, CS - pin 4 (CS pin can be changed)
and pin #10 (SS) must be an output
** Mega: MOSI - pin 51, MISO - pin 50, CLK - pin 52, CS - pin 4 (CS pin can be changed)
and pin #52 (SS) must be an output
** Leonardo: Connect to hardware SPI via the ICSP header
Pin 4 used here for consistency with other Arduino examples
