Hello All,

I'm working with capsense buttons example code provided with CY8CKIT - 046 KIT.

I'm trying to integrate UART in interrupt mode, and it's not working. It seems system goes in sleep mode and hence it's not working. 

Can someone please shed some light, what's going on?

Hi Ashish,

You seem to not have not checked "Rx FIFO not empty" in UART SCB component configurator window. (UART Advanced tab)

Pls enable the "Rx FIFO not empty" interrupt source and check if ISR is triggered.

Thanks,
Shanmathi

Pls let us know which code example you are using or you could also attach your project.

Also, elaborate on your issue so that we can reproduce it at our end.

Thanks,

Hi,

Please find the project in the attachment for your reference.

Capsense buttons are working fine while UART interrupt is never triggered when I send some data over UART (using Putty).

Regards,

Ashish
