I have wired ILI9341 displa as attached schematic…and have problem that i want to use PIN12(MISO) for TFT_DC command so that my display can work…how can i do in arduino which command to enable sending DC command throught PIN12(MISO)?
I im using adafruit library for display and if i use PIN9 for TFT_DC it works, but i need to use MISO for that purpose because i like to have all 4 SPI ports used for TFT connection.
Here is how i define and it does not work TFT:
#define TFT_CS 10 #define TFT_DC 12
And when u define using this:
#define TFT_CS 10 #define TFT_DC 9
Then TFT works.
I know that MISO is SPI designed to read from slave SPI device, but i don’t need MISO to connect to my TFT because i don’t need to read TFT device ID, so i need to reuse this pin for DC (Data Command to display).
What code i need to put to Arduino IDE to make it work?
