MSP430FR6043: solution pls

hence this parameters is for 200khz...

i need the detailed explanation for envelope crossing threshold ,start ppg count ,turn on adc count ,start ppg and in bias count ,external amplifier

Hi,

For 200kHz transducer, it is recommended to start with F1 170kHz and F2 230kHz at the beginning to test with. Your current configuration is F1 150k and F2 152k, it will cause the library keeps reporting error. 

For the meaning of those parameters, please refer to this academy. https://dev.ti.com/tirex/explore/node?node=A__AURAjHTDa0oVdd-2UTgIEQ__MSP430-ACADEMY__8HaEUeq__LATEST

Hello forum,

by changing the parameter i have got graph as 

kondly check this for get an perfect adc graph

This  is my ac capture ....kindly help me got an perfect graph

Hi,

A lower gain setting is preferred, it will lower the DC offset. Keep the maximum ADC data around 600 to 800 codes.

had tried for an good adc capture ..where i have changed my capaure duration  to 32us and reduced gain to 2.6db where i repeately got the error as 

...how ro solve this error

HI,

You can change this parameter USS_ALG_MAX_SAMPLE_SHIFT in the code to avoid this error. By default it should be 20, you can try with 40/60/80.

Hello forum,

now i got my graph in below...i didnt change any parameter even in above mention uss_alg_max_sample_shift .....because i didnt get any error while run with same paremter in today start of my work

anything i still need to change ....
