Other Parts Discussed in Thread: ADS1298, , SYSCONFIG
Dear sirs,
We are starting to develop a new product to read data from 4 ADS1298 at a minimum of 250/500 samples/s. As we have to send the samples through Wifi, we have chosen the CC3235SF as the main host to perform this task. Although we are very familiar with Simplelink product, this is the first time that we use this microcontroller.
Currently we are already sending fake data at the needed throughput using UDP packets with the launchxl-cc3235sf. Our SDK is 6.10 and we have modified the included example program named "udpecho" to carry out this transmission with success.
Now, we intend to test the interface with the ADS and change the fake data by real data coming from the ADS. We have already experience with ADS since we use it with our products that are based on the CC2642R1 IC. However, for this design, we have several doubts:
1. In this program (udpecho), there is already defined a SPI (CONFIG_SPI_0). Can we use it for reading data from the ADS or it is already in use to communicate with the networking subsystem?. If this is the case, can we add a new SPI? . SysConfig does not give us the chance to add another one. Is that right?. Do we need to share this one?
2. Could you please advice us if the CC3235SF will be able to cope with the 4 ADS through SPI?. Should we connect them in daisy chain?
Looking forward to hearing back from you
Thanks
