when using Psoc Creator, it always comes out an alert notice to recommend updating the component from Peripheral Driver Library 3.1.1 to Peripheral Driver Library 3.1.2 , what's the difference between 3.1.1 & 3.1.2? which one is better to analyze the touch signal?

You can find "pdl_release_notes.pdf" at C:\Program Files (x86)\Cypress\PDL\3.1.2\doc.

There is a section "New Features", all I could find there was mention of BLE 2.5 though.

As there could be some more 'undocumented" bug-fixes included,

I would recommend you to use the newer one if you have choice.


P.S. Just from my curiosity I ran the following shell script from Cygwin




old=/cygdrive/c/"Program Files (x86)"/Cypress/PDL/3.1.1

new=/cygdrive/c/"Program Files (x86)"/Cypress/PDL/3.1.2

# cd "$new"

for file in `cat filelist`


cd "$new"

cmp ./"$file" ../3.1.1/"$file"



And there were 1382 files which have different part between 3.1.1 and 3.1.2 from 4710 files in 3.1.2.

So apparently there were more changes than the description of the release note.
