Functional Features of my development board

February 4, 2010

It had been a long time since the development board was manufactured. I was able to test some of the features of the board. I am done with the H bridge, RS232 communication and the A/D conversion. All were successful.

I realised the importance of input filters only when I blew up the microcontroller by connecting the 12V DC motor to the power supply that is not provided with input filters!

I tried pulse width modulation with my board and I have included  a video that shows the motor running at slow speed in opposite directions.

Interaction of the PIC with the PC using MikroC routines

The MikroC routines for the PIC microcontroller were handy to test my board. In the picture, I was able to send a data to my PIC and echo it back to the PC!

I am yet to program the correct sequence for energising the sequence of the stepper motor coils.
