Hi, I am using stm32F767zi controller board with STONE 15" display.
We are having trouble receiving data from the LCD panel.
When we try to receive registry entry (8 Bytes) the system works fine, but when we try to read the variable register, the received (9 Bytes) are not being received correctly. we are using 2 different integer arrays for receiving 8 bytes and 9 bytes of data.
Following is the sample code
uint8_t read_var[7]= {0xA5, 0x5A, 0x04, 0x83, 0x00, 0x00};
uint8_t read_page[6]= {0xA5, 0x5A, 0x03, 0x81, 0x03, 0x02};
uint8_t read_sc_rcv[8];
uint8_t buff[9];
// Register transmit & receive
HAL_UART_Transmit(&huart3, read_page, 6, 100);
HAL_UART_Receive_IT(&huart3, read_sc_rcv,8);
//Variable transmit & receive
HAL_UART_Transmit(&huart3, read_var, 7, 100);
HAL_UART_Receive_IT(&huart3, buff,9);
Thank You
