TMS320F280025: CMPSS configuration

Hi Joe,

As shown in Table 14-2. Analog Pins and Internal Connections from TRM, there is no mux option CMP3_LP4 in 48-pin package. So, there would be error if user set this value.

If the device package is other than 48-pin, user should press "Show Device View" from right side of SysConfig GUI.  

Then click on "SWITCH" button and select the desired package.

Regards,

Hadi

Hi Hadi,

We use the 80pin package, so we need to use the SysConfig GUI to set the pinmux? and also if we program has any error? thanks.

Hi Zhang,

if you're not using SysConfig GUI, then there is no concern about pin selection. You can pass the value CMP3_LP4 to the function AsysCtl_selectCMPLPMux() shown in your code snippet.

Regards,

Hadi
