Hi All ;AD7294 initial as Register:0x08 data:0x03,Register:0x09 data:0x1000.
Is it Vin0 and Vin1 will auto transfer to Vouta and Voutb?
The Auto cycle mode can be enabled through D12 of the Config register(0x09). The Vin0 and Vin1 are uncommitted ADC analog inputs, while the VoutA and Voutb are buffered analog DAC outputs. The ADC conversion result of Vin0 and VIn 1 can be read in the result register (0x01) while the DAC digital code can be written on the addresses 0x01 to 0x04 and corresponding voltage output is read in ins Voutx. The i2c bus will determine if this register is a ADC result read or DAC code write.
Thankes for your help.
We are read result register (0x01) ,but can not get the correct value of Vin0 and Vin1.
IF only enable Vin0 or Vin1 , then can get right data.
Enable Vin0 in first 16 bytes(result register(0x01)).
Enable Vin1 in second 16 bytes(result register(0x01)).
