RF430FRL152HEVM: Request for Clear Code to Transmit and Read ADC Values via NFC

Waleed Alshaibani

Part Number: RF430FRL152HEVM
Other Parts Discussed in Thread: DLP-7970ABP, MSP-EXP430FR4133, , RF430FRL152H, MSP-FET

Tool/software:

I'm using the RF430FRL152HEVM to send ADC values via NFC, with the reader setup consisting of the MSP-EXP430FR4133 and DLP-7970ABP. Although the wireless connection is established, the data received doesn't match the ADC values. Could you please provide clear codes that:

1- Store the ADC values for NFC transfer in the RF430FRL152HEVM.

2- Read the transferred data from the reader (MSP-EXP430FR4133+DLP-7970ABP).

Attached  are the CCS codes I'm currently using. Please feel free to run it and add any modifications that can help with sending a specific value and receiving it at the reader.

Thank you.

    Hello Customer, thank you for your question and interest in our products.

    The forum support of this product has been reduced to first reference our existing documentation and collateral. For support, please take a look to the “Similar Topics” section at the lower right of the thread page. In addition, please consult the existing collateral in the “Technical Documentation” section of the RF430FRL152H product web page along with the Frequently Asked Question document. Alternatively, you can use the search engine of your choice to look for related E2E threads. With each of these resources we believe it will help with your question.

    I will suggest run the default mode using the stored firmware in ROM. Are you measuring the correct ADC value?

    Hi Charles

    Thanks for getting back to me! I'm measuring the correct ADC value from ADC0, which is connected to the light sensor on the RF430FRL152H EVM. In debug mode, I can see the value is around 500 mV. My goal is to store this value and send it via NFC to a reader. According to TI's documentation (Application Report SLOA233), the reader setup is the MSP-EXP430FR4133 with the DLP-7970ABP.

    I've tried to get this working for the past month using the RF430FRL152H EVM, MSP-FET, MSP-EXP430FR4133, and DLP-7970ABP. I've checked almost all related documentation and E2E threads,but I haven't had any success. That's why I'm reaching out for help with the transmitter and reader code to ensure compatibility and avoid getting lost in the coding.

    I really appreciate your assistance!
