MSP430FR5043: "Start PPG Count(ns)" and "Turn on ADC Count(ns)"

MSP430FR5043: "Start PPG Count(ns)" setting range

HI team,

(same opportunity and related questions from the quoted E2E thread)

1. When they set "Start PPG Count" under 33,000, there are no output value of flow rate.

2. At specific relashionship in "Start PPG Count" and "GUI Based Gain Control", there are some mysterious thing. When gain is only 26, 36, or 56, it shows flow rate, but other than them, no output. In addition, when gain is 26, flow rate is output once, but there will no change after changing the reference flow rate (measured gas).

Do you have some idea to resolve this problem?

Regards,

Hayashi

    Hi Hayashi,

    Is the GUI returning any errors when you do these things? Additionally when you do this, can you see a result in the ADC capture window?

    The things you note are not outside of our specified min/max, but these do represent physical values that could lead to the algorithm or the hardware not behaving correctly. It may be helpful to see your ADC captures in this case. 

    Additional question: are you using the EVM430FR5043? Or other hardware?
