Hello, 

 

To contol a H-bridge (LMD18200), with a 8-bit PWM signal, I think to use the SX-28. I'm waiting for the C compiler, but maybe it takes to long. The PWM freq is 20kHz, the PWM steps 0-255. A HALL sensor will sent a puls and a direction (0/1), to get the position back, and with some PD algoritme. 

A serial input must by use for sending a new setpoint. First i will start with the PWM. I have not much experience with the SX, therefore any help is wellcome. 

 

spec: 

clock: 50Khz

PWM: 20khz, 

PWM steps 255. 

Serial: 9600/19200 baudrate         

Hall encoder speed ~500/sec 

 

Is this realistic ?

 

Best Regards 

 

Rob.
