SSD1963 Initialization

I am trying to get a 7" LCD to interface with a STM32F407VET6 microcontroller. I am using a display from winstar which the product number is WF70A2TIFGDBT0. The screen is 800x480 pixels and uses 8080 interface. The display uses a SSD1963 driver and I...

PSRAM Issue with STM32L4R9 Discovery Kit

Hi,Currently I am working with STM32L4R9 Discovery kit. The connected PSRAM model with this board is IS66WV1M16EBLL-55BLI. Using HAL functions, I can only write and read up to 16 bit data (i.e. unsigned integer 8 bit (uint8_t) and uint16_t). Other da...
