Stm32 read serial data out from AD ic

Question asked by Tai Nguyen on May 3, 2018

Hello all,

My stm32 has some tasks :  data change as slave in RS485 network; output an analog signal; read an analog input via serial data out from AD ic.

 

My AD ic return data SDO as below:

SCLK is 32.767kHz. The clock source is too small so I cannot use SPI. Please show me best way to read SDO signal. My stm32 will lost data from AD ic if I use USART interrupt.

 

Thank you.
