Hi,
We are interfacing STM32 with LMP91200 via SPI
Using SPI driver we could configure the LMP91200, once we write the new value, we can read the old value of LMP91200.
Configuring pH
Write data: 0080 Read data: 8080
Configuring Pt1000
Write data: 8080 Read data: 0080
Configuring pH
Write data: 0080 Read data: 8080
But VOUT remains the same irrespective of register setting.
it gives pH output across VOUT and VOCM pins, we couldn't read ph across VOUT and GND / Pt1000 reading.
