************

LCD panel takes eight I/O pins ( 8-bit parallel data bus )  LCD_D0 to LCD_D7.

SD card needs another four — select, DI data in, DO data out and SCK  data clock.

But the LCD panel needs another five pins (RST,CS,RS,WR,RD) to control the eight-bit data bus, taking up five of the six analog I/O pins. So in the end, there’s just one analog I/O and two digital I/O pins left for other uses in your project

 

*********

Pour les images :

It takes any 320-pixel wide 24-bit BMP image located in the root of the MicroSD card, loads it up & displays it.

Save any bitmap image BMP from your PC on to a Micro SD card using card reader.Make sure that the .bmp FILE SIZE does not exceed 250KB.You can make use of PC application like IRFANVIEW to resize the image & save as .bmp file of required size.If the file size is large “File not found” error will be the response.

Principe du « ToucScreen » :

FIG_01

On a donc 4 entrées/sorties X+, X-, Y+ et Y- et une valeur de pression Z

    Great job ! I bought a display from banggood , came with the other chip, I believe it is a ILI9341. Your edited library make it work nicely !

    Still, the colors are not right, I do not manage to get them right, almost no red, Any idea ?
    Thank

    Hi, great job!
    unfortunately I cannot use the SD card neither with Leonardo, nor with MEGA256. Do you have any Idea how to get the sd card running which is included on the TFT?
