Part Number: ADS1282
Hello, was testing ADS1282EVM board. But I am unable to read register map default values as given in the datasheet. I read the default values as random values at every runtime.
+VA and -VA of MMB0 is connected to +15v and -15v (max input as specified in the user guide) and GND to GND of supply.MMB0 is configured as figure 7 of section 9.3.1.
ADS1282EVM configuration is left unchanged i.e. switch S1 chooses onboard reference 5v (unipolar mode), Jumper J3 chooses onboard 4.096MHZ as clock source, all heads of jumper J7 shorted and rest as shown in figure 4 of section 8.3.
SPI MODE = 0
SPI SCLK = 1.024 MHZ
I am using esp32 to communicate with ADS1282 via J5 (GND, SCLK, DIN, DOUT and DRDY pins).
Program Flow:
1)Holding SCLK pin low untill 64 drdy low event is detected to reset spi interface.
2)Sending commands Reset and then Wakeup after 10ms.
3)Each Commands SDATAC, SYNC, RREG + 0x00 (starting from 'ID' register) and then 10(total 11 registers) sent after 10 ms.
4)11 '0x00' transmitted and receive buffer of same size read.
