So, it's nice to have this finally confirmed - and out of the way! :)ĬodeVision is an entirely independent, proprietary 3rd-party product - it's a completely different compiler & IDE.

I did however measure the time between two breaks at line 197 in *_main.c, which is in the `tcc0_overflow_isr()` interrupt that takes 1 minute and 21 seconds on my machine and since that interrupt is supposed to run each 40 ms, that means a factor of 81/40e-3 ~= 2025 between the PC simulation real time, and ATxmega processor (simulated) time. So I set off the simulator, went to lunch, came back, did something else for like 5 minutes - and was surprised (pleasantly) to see Atmel Studio debugger/simulator suddenly break at the next breakpoint!Īlso, the other glcd_* commands take somewhat less time: `glcd_init()` takes 4 mins 21 seconds to simulate on my desktop machine while `glcd_setcolor()` and `glcd_line()` take significantly less - up to 10 seconds max, so I didn't even bother measuring the simulation time for them.

The only reason I figured this out, was that the code setup implies that more-less all of the I/O lines on the ATxmega, involved in communicating with the ILI9341 GLCD are defined as outputs therefore there cannot be any reasonable waiting for a specific input condition.

So, my question is - is there any way that I can "persuade" the Atmel Studio simulator to keep going with the GLCD functions (such that any given breakpoints in the code execute), mostly for the purpose of getting a bit more accurate timing in the simulator - provided that the GLCD libraries that come with CodeVisionAVR are commercial and closed (and thus, there is no source for them)?Īpologies for the false alarm - it turns out, Atmel Studio 7 *can* simulate GLCD CVAVR code just fine! Except, at times, it can get *extremely* slow - for instance, `glcd_clear()` needed some 20+ minutes to complete simulating on my desktop machine, that runs Atmel Studio 7!

Now, I've met this before, and usually the way I handle it, is comment all glcd functions - which is a bit tedious, for one but more importantly, commenting also changes the timing of the running code.

My guess is that the GLCD library functions apparently wait for some hardware response from the GLCD, - but as this is in the simulator, there is no model for the GLCD, and such a response/signal never arrives? R24 simply counts down from 255 to 0, and then it wraps, and then it counts down again - and this loop is never exited. I've inspected a bit, and all that I can notice is, that when this code runs in the simulator, it gets stuck in an endless loop in assembly here:Ġ0000AD8 SBIW R24,0x01 Subtract immediate from wordĠ0000AD9 BRNE PC-0x01 Branch if not equal Rather, the simulator starts up, cycles and PC change as expected - however, the same breakpoints (lines 176 and 199 in `test_xmega_ILI9341_glcd_bp_main.c`), that hit properly in the live debug session with Atmel-ICE, never hit here in the simulator ?!

That which puzzles me, is that I cannot simulate this code in Atmel Studio 7. Also, setting breakpoints in this code in Atmel Studio 7 is also fine - the breakpoints stop the program, both in the main function, and in the interrupt.

Please find attached a zip file, with a simple CVAVR project that uses a clock interrupt at 40 ms to increase/decrease a variable, and a main function that uses that variable to draw a line on ILI9341 GLCD display.Ĭode works fine on ATxmega128A1U, everything is as expected.
