Other Parts Discussed in Thread: OPA320
Hi ,
I am Rahul from WT microelectronics.
One of my customer using ADC8331 and communicate with MCU through SPI.
Issue is that data received by ADC is not correct.
Please check below
Data received.= 0X17CE(6094)
TAG BITS= 0b0100000000000000
but pin voltage is 2.462V @ channel no. 2.
Vref = 4.105V
CFR= 110011111111
packet to read data = 0b1101000000000000
Dummy to receive tag bits = 0b1000000000000000
in images
blue is clock
yellow is Chip select
green is SDO(MISO)
pink is SDI (MOSI).
Please help to solve this issue.
thanks
