MSP430I2041: MSP430 Metrology - calibrator gui questions

Part Number: MSP430I2041
Other Parts Discussed in Thread: TIDM-SERVER-PWR-MON

Support,

I am using the TIDM-SERVER-PWR-MON EVM and Calibrator GUI.

1. where is the polling interval from GUI --> MSP set?  I've searched the XML files and did not find it.  Did i miss it?

2. What type of filtering, if any, does the Calibrator perform on erroneous values? i.e. Power Consumption may jump to all 0xFFFF due to glitch but then return to correct values.  In a system that does not use the calibrator, i.e. host MCU talking to the MSP, it needs to perform the same step.

Regards,

Marc

    Hello Marc,

    I'm not sure of the polling interval set on the GUI side, but regardless, it's not configurable in any provided files unfortunately. If the polling frequency isn't provided in the EVM's user's guide, then the best way to determine the period would be to use a logic analyzer on the UART lines between the MSP430 and the GUI (without HV applied).

    Also, I'm not sure if the GUI does any filtering. I really doubt it does. If you're seeing 0xFFFF, I would suspect an overflow condition rather than a glitch. If the code on the MSP430 has been changed, perhaps the packets are larger than what the GUI is expecting or something similar.

    Regards,
