CCS/TMS320F28379D: The external connector to the 180-pin edge connectot

Min Zhang

Part Number: TMS320F28379D

Tool/software: Code Composer Studio

I just drop here a hardware question, i am try to use external sensor board designed by myself to provide several feedback or reference signal in order to complete a control strategy. I can see in the analog mapping there is a few spare ADCs, for example, ADCC4 and ADCC5, however, there is no connector can get access to these pins on board. There is possibility to soldering , but it is very tight soldering, will be very difficult. Just got a idea that if i can have a external connector in the intermediate stage between control card and 180 pin connector. And the connector should be able to have better soldering oppotunities. Anyone done this , or anyone got a better suggestions, please let me know.

Thank you

TI does not provide such an intermediate stage.

Just asking if there is anything not TI i could use as a intermediate stage.

Min,
Just to be clear, you a asking about a custom base board for the F28379D control card? Just want to make sure since the TI docking station does bring all the analog signal out to the ANA headers.

If there is not access from the 180 connector on the bottom, note from page 4 of the schematic that all the analog inputs also dual route to an ESD protection IC, (U6-U11). You could consider tapping into the analog signals there before they get to the 180 pin connector.

Best,
Matthew
