I found what can be the cause of the problem. It seems that a 10uF+/- 10% 6.3V and a 10uF+/-10% 10V ceramic capacitor don't have the same characteristics, so when I change from a 6.3V to 10V the circuit the time delay increase from 12s to 18s (I have tested different capacitors of both type and...
Hi
I am using an TLC555C chip from Texas instrument to form a monostable timing circuit (see attachment). When simulated this circuit gives a delay of approximately 17s, in real tests using a 10uF ceramic capacitor the delay is approximately 12s and 18s with a 10uF aluminium electrolytic...
Memory mapping in AvrStudio 5 (AVR GCC)
Hi
I am trying to address an external device from an atmega 128. I want to set the external device start address at 0x8000
Here is an example how this was done in an old version of codevisionAVR:
#pragma warn-
unsigned char Chip_base[0x8000]@0x8000...
Hi
I am trying to write the code for connecting a device to Matlab, I have got the documentation for the device and the code is written on the EMT platform and use CPL commands. I have no experience with CPL so if someone could recommend me some links where I could get more background information.
Hi
I included PwmOut.Vhd and compiled PwmOut before PwmController was compiled, now quartus finds the file but I get some errors on the In and Out Signals on the Port map. I have attached my code, how I want the circuits to corporate, and my including.
Could I have misunderstood the use of a...
Hi
I am trying to include a sub circuit into my VHDL code. But quartus gives me the following error: design library "work" does not contain primary unit "PwmOut", this happens when I move the whole subfolder in the working directory, and also when only the sub project file is moved into the...
I did some change in the code sequence, and no its debug correctly until the line:
angleFloatBeta = acos(argument); /*calculate the arc cos */
when stepping through this line the debugger jump straight to the end of the code without updating variables/registers. It seems like the debugger...
Hi
To avoid the size problem you mention, I am using the If-statement to check the size of the in value.
Could the problem be that I am reading a 10bit value from the ADCW(ADCL+ADCH) into a 16 bit integer value. The ADCH register uses only the two lowest bits (if right adjusted). I am reading...
Tnx for replay Alex
I did the change that you suggested, and downloaded the code to the target. I am still getting strange outputs at the atmega16.
The out value is much to high. I did a test and removed some of the code and just outputted the read ADC value at the outputs. I am still getting...
Hi
I hope someone can help me to find the bug(s) in my code (Atmel Atmega16). I have tried to debug the code, but could not get the debugger in AVR studio4 to work properly.
I have tested and know that the interrupt and the reading from the ADC works as expected, but after this I have at least...
Hi
Tnx for good advice. I will check out the documentation. Do you have any tip where I mess up in my code? I know the interrupts is working and that the ADC value is read, but after this I have a bug. The purpose of the code is to read a accelerometer value, calculate the angle of this and...
Hi
Tnx for replay. I am new to atmel/AVR studio so this optimization doesn't give my any meaning. I found in the configuration that I am using -Os optimization. What does this mean? What is the difference between the different optimizations levels? I am using GCC, but how do I debug the...
Hi
My program is not working as expected, and of this reason I am trying to find the bug with help of the debugger in AVR studio 4. When I step throw the code the debugger would not step into the If-statement, and I get no response in the output register (PORTB and PORTC). I hope anyone could...
