Hi,
Im tring to make the ADS8584S work with a SAMD51 however the output data seems to be wrong.
AIN_1P is connected to a static 2V output.
AI1N_1GND is connected to GND.
The rest of the ADC Input arent connected.
PAR/SER/BYTE SEL is set to HIGH.
DB15/BYTE SEL is set to LOW.
STBY and RANGE are set to HIGH.
There is a 100ms delay after STBY is set to HIGH
REFSEL is set to HIGH.
RESET is set to HIGH, holded during 1 us and set to LOW.
There is a 25 us delay after RESET.
After that SPI is configurated as follow:
SPI Clock is set to 7.5Mhz (The SAMD51 is a 140Mhz, i tried both 15MHz and 7.5Mhz)
SPI Mode is set to MODE 3.
Only DOUTA is connected.
Any idea what am i be doing wrong?
Thanks in advance and sorry for my english!!
