Hello,
until now I used an ILI9341 display with Touch. Both Touch and display SPI interface come with all pins and I used the following configuration
-DILI9341_DRIVER=1
-DTFT_WIDTH=240
-DTFT_HEIGHT=320
-DTFT_MISO=12
-DTFT_MOSI=7
-DTFT_SCLK=6
-DTFT_CS=9
-DTFT_DC=15
-DTFT_RST=17
;-DTFT_BL=21
-DTOUCH_CS=5
-DLOAD_GLCD=1
-DLOAD_FONT2=1
-DLOAD_FONT4=1
-DLOAD_FONT6=1
-DLOAD_FONT7=1
-DLOAD_FONT8=1
-DLOAD_GFXFF=1
-DSMOOTH_FONT=1
-DSPI_FREQUENCY=27000000
And everything works well. (THANKS TO BODMER)
Now I need real small display with Touch and the only one I coud find is an ST7735 based 1.8 inch.
Link > (Variant: 1.8 inch with Touch)
Before ordering, I wanted to clarify the interface....
The difference to the mentioned ILI9341 display above is that this one's TFT SPI Interface does not come with SDI/SDO but with AO. As I learned from User-Sertup.h:
"// The DC (Data Command) pin may be labelled AO or RS (Register Select)"
OK so far.
But .... until now I used the SDI/SDO/SCK from display and touch in parallel. (SDO & touch SDO wired-or with two diods).
Because of the AO-pin, which is, if I understood right, a combined in/iout, ths cannot be done any more...?
So the question is:
Is there anybody who has done this before? (For sure!)
Regards
Andree
