You cannot clock a timer from the LFCLK, from the TRM (UDB Clocking) -
Consider posting the rest of your project so forum can take a look
“Create Workspace Bundle”
You could use the PSoC4 WDT for the interrupt.
There is a new version of Creator at hand, when you download and install Creator 3.2 early access (it is a beta!) you can have a working RTC component running on PSoC4 and PSoC4 BLE as two example projects.
thank you for your reply.
but it's strange to have a warning about timing delays in the first case.
regarding the 2nd case of TCPWM as I know it's fixed function not UDM.
if both have the same situation you mentioned, so why selecting LFCLK exist in configuration? it mean that it can't be used in programming the PSOC4.
Great news. thank you
I filed a CASE on the timer. In the component catalog its symbol
is shown as fixed, but only UDB is available in PSOC 4, so that
is an error.
Then the tool reports an error because it is not UDB, even though
its config dialog only shows UDB as a selection.
thank you for following.
regarding fixed function I meant the fixed function digital components in the chip like TCPWM, SCB, ... not FF blocks
I don't know how they are handled like UDB or not.
also, I don't know that there are special icons for FF & UDB components, may you give more details about that?
BTW, I downloded new version 3.2 and the RTC component is great.
also new clock configuration look very good.
Turns out there is a bug in Timer component. When you
first palce on schematic the lable under it is F-F, but then
if you open up config, then "apply" it changes that label to
UDB which it is.
Yes the new parts great, eg. with RTC.
