Win7 x64 / BT Serial connection / High CPU #21

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Running the latest MW-WinGUI 2.1 under Win7 x64 with a Bluetooth module 
connected to the FTDI port of the Paris MW controller (@115200), the CPU usage 
shoots up to between 50-70% as soon as I connect to the BT serial port.  
Communication is working however some loops/threads in your code are consuming 
so much CPU that the interface is almost unusable.  If I pause the graph I am 
able to navigate around OK, however I never see the CPU go below 50% when 
connected.  As soon as I disconnect it goes back to zero CPU.  Not sure if this 
is specific to just the BT connection method?

Apparently it is a driver issue, when connected WinGUI constantly polling the 
MW controller via serial connection. Some bad BT drivers could cause high cpu 
util under these cisrcumstances. I'm afraid it is not repairable on the WinGUI 
side.
