Please use synchronous mode of USART. Details are described in section 24.3.8 of RM0008.

Hi,

I try to interface the same LCD on a STM32f103RB and I have already test your method to send the ninth bit. But I can't manage the LCD.

I think I have a problem with the SPI setting.

Can you tell me how you have configured the SPI ?

Thank you in advance :p

PS : This is my actual SPI configuration :

- no bidimode

- no CRC

- 16-bits data frame format

- Full duplex

- Software slave management disable (I use the GPIO to set and reset NSS)

- MSB transmitted first

- fPCLK/256

- CK to 1 when idle and the second clock transition is the first data capture edge
