Part Number: MSP432P401R
Other Parts Discussed in Thread: MUX36S16, ADS124S06
Tool/software: Code Composer Studio
Hi,
I am attempting to create my own ADC design for this research project I am working on. I am utilizing 6 MUX36S16 that are then connected to the 6 inputs of a ADS124S06, which is then connected to a MSP432P401R Launchpad through SPI. I have a few questions that I need help with:
1. The way I plan on using the MSP432 is to send a signal to all the multiplexers so that each one selects the same pin. The multiplexer then sends that voltage to the ADS124. The microcontroller then runs through each pin on the ADS124 and collects the data from each pin. The microcontroller then adjusts the signal to the multiplexer and the next pin on the multiplexer is selected and the cycle repeats. I believe I can sort out how to use SPI to get the data from the ADS124. My question is how do I configure 4 pins on the microcontroller to set them high and low and send that data to the multiplexers?
2. I have the SIMO, SOMI, and SCLK pins sorted out (P1.5-1.7), but I do not know where to send my START/SYNC, DRDY, RESET, and CS pins. What pins on the MSP432 should I use for these 4 pins?
Please let me know if you need any more information from me. This stuff is a little out of my reach so I may not have explained things are clearly as they should be.
Thanks,
Spencer
