Posted on December 09, 2016 at 07:28Hello Everyone, I have some questions regarding 'HAL_SPI_Transmit_IT(SPI_HandleTypeDef *hspi, uint8_t *pData, uint16_t Size)', the definition of uint8_t *pData and the how did I know the uint16_t Size to write with what? I wnat to use the HAL_SPI_Transmit_IT to show on the LCM, but Only can display from top to bottom, I want to know can I show the data on the LCM with Specify Block, like(20(X1),10(Y1),30(X2),50(Y2)).
