// Setup for STM32 Nucleo and ILI9341 display //

// Last update by Bodmer: 28/11/19
// STM32 optimised functions are not yet compatible with STM32H743 processor.
// The STM32H743 does work with the slower generic processor drivers
//
// REMINDER - Nucleo-F743ZI and Nucleo-F743ZI2 have different pin port allocations
// and require appropriate selection in IDE. ^---- Note the extra 2 in part number!
// Define STM32 to invoke STM32 optimised driver (optimised fns only tested on STM32F767 so far)
// so you may need to comment this out
#define STM32
// Define the TFT display driver

// MOSI and SCK do not need to be defined, connect:
// - Arduino SCK to TFT SCK
// - Arduino MOSI to TFT SDI(may be marked SDA or MOSI)
// Standard Arduino SPI pins are(SCK=D13, MOSI=D11) this is port pins PA5 and PA7 on Nucleo-F767ZI
// Can use Ardiuno pin references, arbitrary allocation, TFT_eSPI controls chip select
#define TFT_CS D5 // Chip select control pin to TFT CS
#define TFT_DC D6 // Data Command control pin to TFT DC (may be labelled RS = Register Select)
#define TFT_RST D7 // Reset pin to TFT RST (or RESET)
// Alternatively, we can use STM32 port reference names PXnn

//#define TFT_DC PE9 // Nucleo-F767ZI equivalent of D6
//#define TFT_RST PF13 // Nucleo-F767ZI equivalent of D7
//#define TFT_RST -1 // Set TFT_RST to -1 if the display RESET is connected to processor reset
// Use an Arduino pin for initial testing as connecting to processor reset
// may not work (pulse too short at power up?)

#define SPI_FREQUENCY 20000000 // 27MHz SPI clock
//#define SPI_FREQUENCY 55000000 // 55MHz is over-clocking ILI9341 but seems to work reliably!
//#define SPI_READ_FREQUENCY 15000000 // Reads need a slower SPI clock, probably ends up at 13.75MHz (CPU clock/16)
//#define SPI_TOUCH_FREQUENCY 2500000 // Must be very slow
// This has no effect, transactions for STM32 are automatically enabled
