btw. Currently I'm using 8MHZ internal crystal and prescaler can be optimized later.

cdi.png Hi gurus, Good day. I'm trying to build my own programmable conditioning stage that can be added to simple CDI units for motorcycles. Having an oscilloscope and signal generator is what I can think most useful tool for this project but Affordability is my main issue. That is why I would lik...

Hello gurus, I'm trying to build a programmable CDI ignition advance timing controller. It can be added to existing analog CDI. I'm making it in mikroc. Algorithm: 1. Connect the pulse sensor to CCP1 pin. 2. The 1st pulse resets TMR1H and CCP1H. 3. 2nd and incoming pulses captured by the CCP1H. 4. A...

thanks Sparky1039.

Hello guys,

Just want to have any suggestion about my circuit. The pulse sensor generates higher voltage that the pic input can handle. If the zener diode goes bad, then higher voltage goes into my pic input.

Any tips.

Thanks in advance.

Hi Gurus, I'm a newbie and want to understand how oscillator and instruction cycles works. I have the code below; [code} int a;=0; while(1){ a++; }[/code] If I'm going to use 4mhz oscillator. Does variable a increment exactly every 1μsecond? Or does the while command and spaces/blank line takes 1μs ...

thanks Filip. but I would like to make the code smaller/shorter as much as possible. I'm building a programmable ignition module for CDI in mikroc. I've tested the code in C and it works. But seems that it will have the same number of conditions as the IF-Else statement. #include <stdio.h> int main(...

Thank you Robert.

Is this functionality added?

This is a sample code I'm trying to solve. if (ptime ==1000) { pdelay = 245;} if (ptime >1000 and ptime <=1025) { pdelay = 240;} if (ptime >1025 and ptime <=1050) { pdelay = 235;} if (ptime >1050 and ptime <=1065) { pdelay = 230;} if (ptime >1065 and ptime <=1085) { pdelay = 225;} if (ptime >1085 an...

Any idea on what is best alternative for the below conditions? < 100 = 1ms delay >= 100 and < 200 = 2.. >= 200 and < 300 = 3.. >= 300 and < 400 = 4.. >= 400 and < 500 = 5.. ..... >=1xxx < 19xx = x Can look-up table be used?

Hi gurus. I'm just starting to learn/study pic programming using mikroC PRO. What is the difference on the below statements; RA1_bit = 1; PORTA.B1 =1; PORTA = 0b00000010; or the equivalent; (PORTA = 0x2 , PORTA = 2) and INTCON.GIE = 1; INTCON.GIE_bit = 1; INTCON = 0b10000000; Is there a general rule...
