#101602 - Works perfect at my place! Responding to: ???'s previous message |
Hi Vimal
I tried your little code bit, and below you can see my result. As you can see, it compiles, link and locate perfect. I have used standard setup + I checked the assembly listing under compiler options. I've been using SiLabs IDE for a year now, and never experienced problems. By the way: Why invest in an ICE when it is built into the controller?? :-) Here it comes - pretty long I recommend you to print it out, then it is much easier to follow.
