Part Number: CC2650
Other Parts Discussed in Thread: LMP91000, MSP430FR5969, SENSOR-CONTROLLER-STUDIO

Tool/software: Code Composer Studio

Datasheet of CC2650 does not show UART, SPI and AD pins just show as I/O or GPIO. How can I know what pin is SPI , UART, and so one.
I need 2 UART ( to communicate with msp430FR5969 and DAC8742) and one SPI to communicate with LMP91000 is it possible? Which pins should I use?

You can config all of IO pins as UART or SPI. However, CC2650 only support one UART. If you need two, you have to use sensor controller in CC2650 to simulate second UART. By the way, what is AD pin?

I assume that by AD mean ADC pins. You can use any analog capable IO as ADC pins, see the Pin Description overview in the datasheet which pins these are.

Could you please tell me how to simulate second UART?AD mean ADC pins. Thank you very much.

You can download SENSOR-CONTROLLER-STUDIO and find example code inside.

Thanks . Now I can see one UART and one SPI. I need communicate with LMP90100MHE/NOPB , one DAC8742 and one FRAM memory or CPU with FRAM memory to keep calibration data. If have just one SPI I will have to switch SPI port through the CS pin.How can I do?

You can config different GPO as CS pins to enable different SPI slave.
