I wonder if there is a recomanded way to use windows PC uart with FreeRTOS.
I am trying the FILE way, but having problems with it:
hComm = CreateFile( ComPortName, // Name of the Port to be Opened
GENERICREAD | GENERICWRITE, // Read/Write Access
0, // No Sharing, ports cant be shared
NULL, // No Security
OPEN_EXISTING, // Open existing port only
0, // Non Overlapped I/O
NULL); // Null for Comm Devices
Status = ReadFile(hComm, &TempChar, sizeof(TempChar), &NoBytesRead, NULL);
Here is a recent post about the Windows port of FreeRTOS. It says that you should never call any Windows API from within a FreeRTOS task. Likewise, you can not call a FreeRTOS API from within a Windows thread.
Please have a look at
demo_logging.c (also mentioned in that post): it is a normal Windows thread that does call normal API's. And as I explained, it is difficult to realise communication and synchronisation between a Windows thread and a FreeRTOS task.
You could write something like in
demo_logging.c, in which you get access to a serial port.
Try to work with
handle = CreateFile(
FILEATTRIBUTESYSTEM | FILEFLAG_OVERLAPPED,
The actual access is done with
You are quick !
Thanks for reporting back. Hein
