Other Parts Discussed in Thread: ADS1198
I try to write some code to access the ADS1194 via SPI in python. I have the datasheet in front of me but I’m confused. It is not the first time I use the SPI bus but the datasheet page 27 fig 28 tells me 8 channels from 16 bits and STAT 24 bits for ADS1198. I use ADS1194, means this 4 channels from 16 bits and STAT 24 bits, the data pulsestream is shorter, is this correct?
What do you mean with STAT here?
I know how to follow the chart page 66 and the SPI datasheet page 35 – 50. This is clear but where I find the figure that shows me how to start sending command data and this 24 bits, is this from table 9 ?
Because I have no driver for ADS1194, I use the spi.xfer2 command in python.
So to resume, where are the positions of the command bits, the register bits and data bits in the datastream?
Many thanks in advance.
