thank you for trying to help

problem is solved!
Atmega16 arrives from factory with JTAG enable fuse set and for using all port C pins properly it is nessecary to disable JTAGEN fuse.

v4. i use single pin.
yes i have multimeter,to test the outputs i use LEDs . pins C2 and C5 are low, not changing

Hi David

from what I can see in the datasheet port c can be input/output
but what about the data direction?
it is managed by flowcode when I use OUTPUT or SWITCH components right?
but is it ok to use bothe on the same port?

i dont know wht to do, I even tryied to change the device

is there a problem with that?
i use PC6 and PC7 as switches
and I want PC2 and PC5 as outputs but these two are not working, the switches works fine.
device is atmega16

when I change the fuse of AVR to internal clock the code works perfectly but when I change to external I have a lot of wierd bugs...
should I change anything in flowcode except of the frequency in project options?

Hi I use RTC and I need a way to calibrate the clock capacitor without a scope, the RTC gives output of 1HZ Im thinking to dispay on lcd the number of muc pulses that i count in 1HZ of rtc and then I know that if I have 12MHZ crystal I should change my cap until I see 12000000 on the LCD what do you...

its not a lot too big, it was ok but then I just added a few little changes and it didnt fit
not i'm in a position that if I add even one command it will not fit.

Hi

I use some components like LCD, I2c, switches, RS232, Step motor. is it possible that the compiled code includes also procedures of the components that I dont use in the code? because I cant fit the file in the device (Atmega16)
is there any option to shrink it in some way?

Thanks

the LCD component can work with 8x2 LCD?

Do i have to change something for working with lcd 8*2?
If i select 16*2 or 20*2 in the componnent properties the lcd acts differently.

Thank you for your help Ive changed the clear LCD to start LCD and for now it seems like its ok. if the problem will appear again I will post the code here. I have another problem, I have LCD 2x8 connected to Atmega8 while its working it looks like the LCD is flickering and not working smooth. I tho...

if that is the case (that interrupt is happenning in the middle of LCD routine) than how can I prevent it?
should I always disable INT before importent procedures and enable it again after the procedure is done?
the interupt only sets a flag

Hi I use 4 lines LCD, and sometimes the whole display is full of scrambled characters and it will not return to normal until I will reset the power for the controller. I have only one thought of what can couse this but I'm not sure, I use one INT pin that get a signal every one second, is it possibl...

OK I disabled the CKDIV8 fuse and I think it's working good now!
but just to be sure, is there any configurations I need to make in the flowcode when I change the osilators?

Hi I'm trying to use the internal oscilator of the ATtiny2313 I compiled a simple program for test that switching a LED on and off every 1 second delay and I programmed it to the chip using AVRstudio after setting the fuse to internal oscilator 8mhz and while it run the LED is switching every about ...

Ok. I'll watch it if I will get more corruption I'll use the start command once in a while...
Thank you it helped me a lot!

Thank you for your great advice! If I think now of what I did I see its really not smart to make such a big interrupt routine. As you said I moved all functions out of the interrupt and now the interrupt only change a flag which I check in the main. now just one more thing I'm not sure about, every ...

and what about the LCD_CLEAR ? should I hange it to LCD_START?

the LCD_ENABLE method seems easier to apply but once in a while I will loose some output to the LCD from the interrupt routine, is that right?

Hi,

Yes I have interrupt and both interupt and the main have LCD functions.
How can I prevent the interrupt from running in the middle of LCD function from the main? (the interrupt is occuring every 1 second)

Thanks

I use the LCD component and I have a weird bug in my program, it all works fine but once in a while when the LCD is changing the display I get a scrambled screen with random characters on random places of the LCD. Do you have an idea of what can cause such a thing?

I'm working with AVR (atmega16) and using the LED's component (the pins not really connected to LED's but serves as output for something else) The problem s that the component is set for all port A and when the chip starts one of the pins (PA4) always start in high state, all other pins are low. If ...

Just to be sue, you mean to change avariable according to the switches (for index) and to use decisions for each index number so that each decision will display a different stage of the menu?

I need to use 2d array (of chars or strings), does flowcode support that? I tryied to define an array inside "c code" but when i try to approach the array in other flowcode functions flowcode dont recognize it. What i'm trying to do is to build a menu for 4*16 LCD so i can scroll the menu ...
