For this purpose, SAP and SGP commands are used. 7.2 Main Loop Embedded systems normally use a main loop that runs infinitely.
TMCM-3230 TMCL™ Firmware Manual • Firmware Version V1.07 | Document Revision V1.05 • 2017-OCT-10 17 96 / 103 WAIT POS , Motor0 , 0 JA MainLoop Have a look at the file TMCLParam.tmc provided with the TMCL-IDE. It contains symbolic constants that define all important parameter numbers. Using constants for other values makes it easier to change them when they are used more than once in a program. You can change the definition of the constant and do not have to change all occurrences of it in your program. 7.
TMCM-3230 TMCL™ Firmware Manual • Firmware Version V1.07 | Document Revision V1.05 • 2017-OCT-10 7.5 97 / 103 Using Subroutines The CSUB and RSUB commands provide a mechanism for using subroutines. The CSUB command branches to the given label. When an RSUB command is executed the control goes back to the command that follows the CSUB command that called the subroutine. This mechanism can also be nested. From a subroutine called by a CSUB command other subroutines can be called.
