I am using PI motion controller which has integrated DSP Processor (we don't have any details about the Processor). I have programmed the motion controller to drive piezo motor using MATLAB however i would now want the motion controller to recognize command sent from the UART (UART2) port of LPC2478. I already set the baud-rate and number of bits to be sent identical to the one given in datasheet and i also used the same setting in MATLAB program.
I feel that the 3rd party device is receiving the data but maybe is not able to interpret.
We are trying to send a text based command (like, MOV 1 8)
When we were programing through MATLAB it need certain DLL files but when we are trying to program it via keil , it doesn't support a DLL file. How should we import a DLL file in keil or other than using a dll, will there be any other way to make the motion controller recognize our commands.
