Hello!
First,thanks for your patience!
I'm using ads1255 with a MSP430 to sample data and send it to a computer with a RS232 cable to view the data.However,i received the data completely false.
For example,when i connect AIN0 with 3.3V ,meanwhile,connect AIN1 with ground.The correct data can be like this:54 6C 67(because ads1255 is 24-bit AD,i use three hex numbers to express,and the high byte is 54 ,the middle byte is 6c ,the low byte is 67).But i received like this: FF 54 6C(the high byte is ff ,the middle byte is 54 ,the low byte is 6c) .After several experiments , the result was same.So I use the word--"high byte shifts behind"to conclude this problem.And the circuit is drawn the same as the chip provided.
Can you help me?
Regards,
