So currently I am experimenting with HAL UART APIs and I learnt that there is cy_tetarget_io which helps us to use printf function with UART. I used it with the example project provided and it worked perfectly. But when I tried to include it in my Empty Project I am getting an fatal error. Can anyone please help me with this issue?
Here it is with picture. At first you need to select project to include library. Open any source file in the project. Remember than in case of dual core app there are two projects. Select project in which you want to use printf. Then open Library Manager as indicated in previous post:
Then click Add Library button:
Then mark retarget-io in Peripherals section and confirm by OK.
Then confirm Previous dialog by Update button.
