This program does nothing new with regards to writing commands to the TMCM-1110 compared to what Trinamic provides. It does allow the user to read the reply. The user will need to download the "TMCM-1110 TMCL Firmware Manual" from Trinamic in order to enter the appropriate command codes and to interpret the response. The Trinamic driver should also be installed.
The Build Command.vi replaces Trinamic's "calculate CRC.vi", "decimal to hex.vi" and "value in hex to 4 decimals.vi". It is unclear why they did not combine them into one VI. Particularly since they seem to encourage sloppy and unreadable programs.
The ability to read a reply allows full use of the StepRocker board. It allows the user to
Detrmine the board configuration
Query the end of a move
Read DIO pins
Read ADC channels
Read Home and limit switches
Read an encoder
