Hi,
The ILI9341 display https://cdn-shop.adafruit.com/datasheets/ILI9341.pdf
as on Page #35/233, is it using SPI MODE:3 ? Can someone clarify ?
Slightly confused with the timing diagram for the 4 line Serial interface and hence my question.
I am trying to debug an issue that I am facing on the STM32F334 using it with the ILI9341.
Attaching a logic capture of the waveform, on the SPI bus, writing 0x02:
The code that was used to create the waveform:
/* SPI configuration */
RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE); /* Enable Clock */
SPI_I2S_DeInit(SPI1);
SPI_StructInit(&spi_state);
spi_state.SPI_Mode = SPI_Mode_Master;
spi_state.SPI_CPOL = SPI_CPOL_High;
spi_state.SPI_CPHA = SPI_CPHA_2Edge;
spi_state.SPI_NSS = SPI_NSS_Soft;
spi_state.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_256;
spi_state.SPI_FirstBit = SPI_FirstBit_MSB;
SPI_DataSizeConfig(SPI1, SPI_DataSize_8b);
SPI_Init(SPI1, &spi_state);
SPI_Cmd(SPI1, ENABLE);
for (i = 0; i < 255; i++) {
SPI_SendData8(SPI1, i); /* Send Command byte */
SPI_Wait(); /* Wait for transmission */
delay(5);
}Any thoughts ?
Thanks,
Manu
