In the raw MQX examples there is example of non blocking uart input:
uint32_t ser_opts = IO_SERIAL_NON_BLOCKING;
|retval = ioctl(ser_device, IO_IOCTL_SERIAL_SET_FLAGS, &ser_opts);|
|if (retval != MQX_OK)|
|fputs("TXtask Fatal Error: Unable to setup non-blocking mode.", stderr);|
Unfortunately I could not find the IO_SERIAL_NON_BLOCKING defined inside my project or the KSDK,
is the non-blockin mode removed, or is the interface just changed?
(I just want to check if a char is available from the UART, and if not just keep on with what I was doing....)
