hi,
I'm on testing an ADS1258.Because i'm not not sure whether the hardware works well and unfamiliar with the operation procedure,i want to make a simple operation on ADS1258 GPIOs.After power-on reset,i do nothing but send two 16-bit data --0x6700 and 0x68FF to ADS1258 sequentially.Why is 0x6700 and 0x68FF.According to the command format,i do the following setting on upper 8 bits(command byte),C2:C0-011(write register commnand),MUL-0(single register acess),A2:A0-7(GPIOC)/8(GPIOD).The lower eight bits constitute the data bytes,setting all GPIOs in output mode and high level.I issued the command and data,but found no changes in the GPIO state.Is my idear above resonable?Is there something important i should pay special attention to while writing driver program?
Regards,
Adam
