CCS/MSP430FG4619: Comunicaction between PGA2500 and MSP430FG4619

Hi Javier,

You can find SPI code examples for the MSP430FG6419 in TI Resource Explorer. I recommend using these as a starting place. Then I would refer to the Serial Port Operation section of PGA2500: Digitally Controlled Microphone Preamplifier datasheet along with Figure 2 for a description of the data protocol the PGA2500 uses. It also helps to have a oscilloscope or logic analyzer on hand to monitor the SPI bus and s=ensure what you are trying to send is actually being sent.

If you encounter any issues while developing, please refer to Solutions to Common eUSCI and USCI Serial Communication Issues on MSP430 MCUs for help with common SPI communication issues. Let me know if you have any more questions. 

Best regards, 
Caleb Overbay

Thanks for your response,

I have seen the examples, but when i have the SPI init, i don´t know the instruction to send information from the master to slave. Do you have any idea to how i can do?

Thanks,

Javier
