you can as well just use the "GO_DONE_bit=0" in place of that. Not all c compiler support that method of addressing bits in a register.

What you do is to basically use the AND gate as a buffer, the two input pins of the AND gate are tied together and fed from the Microcontroller and the output is used to drive your DS1307 chip. It has become a standard Norm for me to use this method when I am trying to get out a clean clock signal f...

Whenever I face a problem where I have to touch a part of a circuit for it to work well. I have always had problem with effect of stay capacitance which in turn makes my clock line to be dirty. What I have always done when clock line is dirty is to use a cd4081 and gate as a buffer to get a clean cl...

Thanks to everyone who was interested in reading my post and offering to help. As I earlier mentioned I requested a support ticket with mE and they responded to my query(very impressed). This was the summary of the reply. " Hello, I have tested your program on real hardware. Specifically, I used Eas...

That is what i was talking about any way i have already taken a support ticket with mikroe and i am waiting for their reply. In the meantime I had wanted to use strncpy function to avoid using sprinf but i got pic18 stack overflow reset in in proteus. I can just avoid using mikroc compiler while i u...

this is the proteus file in compatibility mode and you can check it now, in the mean time i have requested a support ticket with mikroe. I have noticed that while the sprintf function leads to uninitialized memory complain in proteus, using strncpy leads to stack overflow causing a reset in proteus.

Any help yet for this post, I have uploaded the schematics and the associated proteus file for simulation purpose, so you can understand what i am talking about as i dont want to go on to design this project on hardware only for it not to work.

I am uploading the project files and the simulation results so everyone can see what i am talking about. I have tried to simulate by creating a 16 by 2 lcd project before with sprintf function and i get similar complains too.

Hi guys, I have tweaked this code a bit based on the fact that i had to use 18f4520 or 18f4550 and the code compiled successfully and there was not a single error from the mikroc pro compiler. but the problem is by the time i try to simulate with proteus i get a load of stack error and error from un...

I have worked on this kind of problem when i was designing my oscilloscope to take negative voltage inputs, I used an opamp as a level shifter by adding an offset voltage such that at -2.5v the output is zero and at 2.5v the output is 5v. those corresponded to a sort of straight line equation were t...

Thanks you guys again for replying to my post. To sonnyK i had to add cmcon = 7 just to see if that would correct the bug of unpredictability that was involved in the code. to acetronics i used clockit initially, i had to change to clockit() just to see if that makes the code work. moreover in c for...

i was looking at the bitmap array generator and i was wondering what the maximum size of such array is that i can create. i want to know whether it is going to be limited by the program memory size of the microcontroller alone or there are other limitation. More over if i create a custom array how d...

To try to tell you an easy way out is not that simple, i think what you should do is to first learn a programming language preferable visual basic.net. with this read jan axelson's serial port complete. even if anyone makes it simpler by giving you code and everything ready to run, you are not going...

thanks guys, i think i figured out how the problem is generated. for some instance you can see from the code that i am trying to change the port a bit at different times. when bit0, bit1 and bit2 of porta is to be changed to different values at different time, setting a particular bit tend to clear ...

#define clockpin PORTA.f0 #define resetpin porta.f1 #define datapin porta.f2 void clockit(void) { clockpin = 1; delay_us(20); clockpin = 0; } void reset(void) { resetpin = 0; delay_us(20); resetpin = 1; } void main() { int x,z;char y; const char loopcycletime=50; const int arraysize=635; const code...
