// GPIO configuration for SPI pins

// Define the block size used for partial screen updates
//   -> Only blocks that have been modified are sent to the display
// Note:
// - TFT_WIDTH must be evenly divisible by BLOC_WIDTH
// - TFT_HEIGHT must be evenly divisible by BLOC_HEIGHT
// Example: For a 240x320 screen, a block size of 24x32 is valid
#define NB_BLOC_WIDTH   10               // Number of blocks horizontally
#define NB_BLOC_HEIGHT  10               // Number of blocks vertically
#define NB_BLOCS        NB_BLOC_WIDTH * NB_BLOC_HEIGHT // Total number of blocks
#define BLOC_WIDTH      TFT_WIDTH / NB_BLOC_WIDTH      // Width of each block in pixels
#define BLOC_HEIGHT     TFT_HEIGHT / NB_BLOC_HEIGHT    // Height of each block in pixels

//-------------------------------------------------------------------------
// FIFO size for SPI block transmission via DMA
// Note: The number is limited due to FIFO being placed in SRAM D1, 
// which may also be used by other processes
#define SIZE_FIFO 5  // Number of blocks in the FIFO buffer
