check wave with oscilloscope in the PC TX pin. Real term is the PC software, you can connect TX and RX together in your COM-USB tool which connect to the PC, then check, when realTerm send data, whether itself can receive it or not.Ģ. Now, your problem is when use real term send data, you don't know whether it is really send. Thank you!įrom your document, we can see that when K53 send data, your realTerm can receive it. Note: If this post answers your question, please click the Correct Answer button. I have attached my test code for your reference. Take TWR-K53N512 board sample code as an example.Īfter enable the RIE, when the UART receive the UART data, it will enter the UART0_isr interrupt. You can get the according interrupt work. You must make sure your fingerprint can work at first.Ībout the uart interrupt for receive and send.Īctually, after you initialize the TIE and RIE in the UARTx_C2, and enable the according IRQ, add the ISR function. Did you use the CommAssistant tool to test your fingerprint before? For example hypertrm.
