How to control 8818EVM using PC

Other Parts Discussed in Thread: DRV8818, DRV8818EVM

Hi:

I am going to write a code using VC++ to control the 8818EVM.

However, I have no idea how to start. Does anyone know the developing procedures or tell me what kind of document I can study?

Thanks.

    Hi

    DRV8818 itself doesn't need coding. All you should do is config the PINs and feed STEP and DIR signals into it.

    Do you mean you want to build your own GUI software to communicate with the DRV8818EVM? if this is ture, you need to get familiar with the UART communication from PC the 430MCU. You can do the STEP control, DIR, PIN CONFIGS by the MCU after receive commands from PC.

    For stepper motor control, you should pay attention to the Micro Stepping, Decay mode, Start up PPS, Acceleration and deceleration, Current setting. Every thing here is to make sure the stepper motor running smooth without missing or over any step during the whole application stage.

    For detailed infomation of above things, just search in www.ti.com/motor and google.

    Thanks.
