Hey...everyone I am interfacing serial ADC.
I need some help , regarding USART in SPI mode, http://www.mouser.com/ds/2/256/M... ... 102916.pdf
It requires 24 continuous clock pulses for one conversion, however I can only get continuos 16 clock pulses by giving one control byte and padding 8 0's. I tried to give padding 16 0's but clock stops after 16 clock pulses. I don't know how to get 24 continuos clock at XCK pin for conversion to complete?
If you see figure 2 in page 11 of the datasheet, adc is required to have 1 control byte before conversion take place , and after that 16 clock pulses gives adc data...I am transmitting control byte followed by two 0 valued bytes, but I only see control byte and one zero byte at Tx pin and clock on XCK pin runs for 16 clock pulses only...how I can extend it to have 24 pulses...
