Hi all,

As part of my work,Blackfin needs to transmit data to DAC and receive data from ADC.I am using BF537kit.For transmission I am using ppi,since only one ppi is there I have opted gpios to receive data from parallel adc.the gpios are receiving junk data every time I send data from ADC.ADC clk is 8.192MHZ

All the settings are default.

 

To start with gpio programming,I gave 8.192M clk to one of gpios and data is showing random 1's and 0's.Instead of showing periodic data,it is giving random.Please suggest me how to get correct data.
