CCS/LAUNCHXL-F28377S: Delay using NOP

Part Number: LAUNCHXL-F28377S

Tool/software: Code Composer Studio

Hello,
I am using this Instruction __asm(" RPT #100 || NOP"). I want to declare 100 as variable. I am doing in this way __asm(" RPT #t1 || NOP") and before void main(void) i wrote this

volatile Uint32 t1 = 100. but its not working.

How would i do this.

You might get some ideas from this.

You cannot interact with asm() statements like that. Instead, use the DELAY_US macro supplied by controlSUITE. Unfortunately, I am not familiar with controlSUITE, so I cannot give you any further detail.

Thanks and regards,
