Teseo LIV4F output data rate configuration

[AlexT]

Hi all,

I have been doing some experimentation with a LIV4F module and am trying to configure the device for a 5Hz data output rate. I see the device supports up to 10Hz.

The commands I have tried via teseo suite are:

$PSTMSETPAR,1190,0.2 followed by $PSTMSAVEPAR and $PSTMSRR

The device replies with $PSTMSETPAROK in repsonse to each command, but there is no effect on the observed data output rate.

I am sure there is something I am missing when in comes to configuring the device.

Thank you for any help.

Hi

You are setting a wrong CDB.

To change the fix-rate you have to set CDB303. see below script to set 10Hz (0.1 value in the command):

1.Set the 10 Hz rate	$PSTMSETPAR,1303,0.1,0
2.Save on flash and 3.Reset	$PSTMSAVEPAR $PSTMSRR

Thanks for the prompt reply Francesco.

I have input your suggested commands, received a SETPAROK and SAVEPAROK.

Using the command $PSTMGETPAR,1303 I get the return $$PSTMSETPAR,1303,1.000000e-01*4C which indicates it should be set to 10Hz.However it does not appear to have any effect on the observed data rate. It still comes through at 1Hz.

Is there anything else I can check?

 Hi Alex

Please check if you are using the latest firmware version 4.6.3 (with commands: $PSTMGETSWVER,255)

The latest version is available on st.com (code: Teseo-LIV4FSW).

You can upgrade the module using the PC windows tool: Teseo-Suite (available on st.com).
