Can I use printf of standard C library to send out data using UART on FX3 ?

[HamburgSteak]

Hi,

I'm developing some products using CYUSB3KIT-003(FX3) these days.

And I would like to use printf() functions of standard C library to send out data on UART.

Is it possible on this product? Is this development environment support this?

If supported, please let me know how to do that.

Hi,

It also depends on the use of printf() function. If you want to print floating variables then you can refer this: https://community.cypress.com/t5/Knowledge-Base-Articles/Printing-Floating-Values-using-FX3-SDK-KBA2... , otherwise CyU3PDebugPrint API can be used.

Can I use printf() instead of CyU3PDebugPrint?
Actuallyl, I'am trying to develop debug module myself instead of using CyU3PDebug module. Is it possible in this platform?

Hi,

We haven't tried using printf () function as we already have CyU3PDebugPrint API. You can follow the KBA I pointed earlier and try at your end. Please let me know if you find issue while implementing it.

Thanks for your helping.

I've decided to use CyU3PDebugPrint API.
