I am writing MQX 4.1 application code for Kinetis MCU MK64FN1M0VLL12 on a custom board. I have a software task that uses USB CDC driver to communicate with a computer through USB Interface. My question is, how to send data to the PC through USB interface by using printf(). I noticed there is a thread in the forum that asked the same question.
Based on the correct answer in the thread, I tried to add this line of code but it didn't work:
g_usb_handle = USB_Class_CDC_Init(...);
/* Add below code */
By calling _io_set_handle I still cannot see the string TEST printed on the TeraTerm Terminal in the PC.
Can anyone please advise what might be the reason for this?
Thanks very much!
