hi all
I am using an LM629 for DC motor PID servo control . The **broken link removed** says that it is necessary to send two bytes of data , the lower byte and higher byte . How is this done with only 8 data lines (PC parallel port). A source tells me that we must send the LB first and then the HB through the same 8 lines.
1 . Is this true ??? .
2 .How long must the data (HB or LB) be available at the input ? .
3. what must be the delay in data transition between the LB and HB ?
4. What must be sent first HB or LB?
thanks.
