    Triac fan speed control

    fan speed control using triac Hi Ave_Rapina Thanks for ur post I am already using a circuit using BT136D and i cannot change it. So using MOC is not practical for me and also using IGBTs is also not good for me. Then using PWM is OK but how??? I am using the same circuit for a...

    Problem with program as the PC jumps to different part of code when adding offset

    Re: Problems... Hi, when u r adding offset to PCL, the content of PCLATH is automatically loaded to the higher byte of PC. So before adding offset to PCL load PCLATH with higher byte of your offset. For Example: If your u want to go to address 0x1000, and if ur current address(PC value) is...

    How to stop the Counter mode is Timer 1 in the PIC16F877

    Hi, 1. Select required prescaler and load T1CON with ur configuration required 2. Set TMR1CS bit in T1CON for selecting External clock, this to configure TIMER1 as counter 3. Clear TMR1H and TMR1L registers 4. Set TMR1ON bit to start counting 5. To stop counting, clear TMR1ON bit. Timer will not...

    LDR design to use analog ports A and E 1(6F877)

    Re: LDR 16F877 Hi, For ur application 16F877A is more suitable than 16F877 because it has in-built Comparator Module. From Comparator u will get a 0 or 1 and also it has internal voltage reference so that u can set ur voltage as required. In 16F877 Connect LDR to any analog channels and...

    Help me write a source code for A/D converter in MPLAB

    Re: source code help!! Hi A=256*B+C For this u hav to write a sub routine for multiplication. This can be done using successive addition. If ur value 256 is fixed then u need not want to multiply it. Simply put two zeros in right side. For example: if B=0x23, then 256*B will be 0x2300, that...
