Hello,
I am reading the SPI communication section of the ADS1298 datasheet and have some questions regarding certain aspects of the interface.
1. When it comes to configuring the chip, let's say adjusting bits in the CONFIG1 register, what order would I have to send the commands via SPI to do this? For example, would I send the address of CONFIG1 and then the values of the bits I want to change?
2. I have a similar concern when it comes to data collection. Let's say I would use the chip in read continuous mode, would I send that opcode first, wait for DRDY to transfer low, and then wait for the data to come from the DOUT line?
3. Is there a way of selecting a few channels of the chip instead of all eight? Ideally, I would like to use one or two channels, but I haven't seen anything in the datasheet yet that clarifies whether or not this is an option.
4. How will the data outputted by the chip look like? Will it be formatted as a binary number (or maybe a hex number)? I am mainly concerned about how I would parse this data when I acquire it in my microcontroller to get the values I need.
Thanks,
Noel Teku
