1.0.0-RC3 at rev 1148 Arduino UNO some HEX doesn't work

What I do:
1. Create new project
2. Add Arduino UNO
3. Load hex which just blinking 13 led

What I expect - led on arduino is blinking.

What I see - nothing.

Code:

I have checked in stable version (0.4.15-SR10) and it works as expected.

Hi.

It is working for me with hex files generated by Avrgcc.
Maybe is something about your compiler, can you share that hex file here? (just copy the content and paste here is ok).

Hi,

Sorry, I thought that I have attached hex file.

Please, take attention - both hex files correctly works in stable version (0.4.15-SR10).

this is blink.txt doesn't work on 1.0.0-RC3

As far as I can  tell, elf file build using avr-gcc. I use avrobj to convert elf to hex:

Code:


avr-objcopy -j .text -j .data -O ihex $ELF $HEX


Thanks for the files, I could do some basic tests.

The problem seems to be that writing 1 to PINB bit should toggle PORTB bit, but this is not working.
I will get into this as soon as I can.

Please, take attention - both hex files correctly works in stable version (0.4.15-SR10).

In this case this is not relevant: 1.0.0 uses a completely new MCU simulator, including .hex loader.

Thanks for reporting.

Solved at trunk Rev 1359.

Please note that from datasheet of ATmega8:
PINx. The Port Input Pins I/O location is read only

Yes but in ATmega328 writing to PINx toggles PORTx bits.

Thank you for this remark.

I missed this info because I don't use ATmega328 so I didn't read its datasheet attentively as I did for ATmega8 (or of any IC I may use in my designs).

I have to be more careful when commenting about something that I don't use, even if it is said being of the same family of what I am familiar to.

I think it is always better to comment too much, making errors is the best way to improve.
In addition sometimes it can bring some insight, for example I realized that my implementation at Rev 1359 had an error: It indeed overwrites PINx register for a brief moment, which can create some glitches (solved at trunk Rev 1363)
.

Hi! I have checked SimulIDE trunk at Rev 1365. Simple blink is really works, thanks!

Here are example which are still not working in Simulide (and works at hardware):

It uses timer1 in CTC mode and changing pin 9 (by MCU)

One problem is that an Arduino pin can't properly drive an 8 Ohm load.
Increase the impedance of the AudioOut component and it will work.

But there is a bug that prevents OcUnit Pin toggle in this case, solved at trunk Rev 1375 (1.0.0 Rev 1156.).
