Hello friends,
I want to begin my carrier as PCB Board Designer. I have done electronics and communication engineering.
How to start learning PCB Board Designing ?
what i want to Know first?
Which tool i want to use?
How is the scope in this field in future?

Hello friends,
I am using PIC16F877A. By "turn off" I mean only one PWM cycle after turn on. I want to control every PWM cycle and decide when it starts, and when it stops.
Please help me with example(codes)
Thank you
Hello,
I am using pic32mx795f512l and i am trying to code for external eeprom (25LC256) to store the last value of LED.
I want to use SPI communication for EEPROM. I need sample code to done this.
Please help me with some sample code.
Thanks in advance

Hi friends,
I want to control the 25w bulb intensity, i am using pic16f877a controller xc8 compiler and also i have attached my code with circuit diagram.
For controlling the AC voltage we need to fine zero crossing, this is done by code through interrupt.
In my code i have used...
Hi Jestin ,
I am doing the same project what you have done. I am getting the all the output wave form by your code, but the bulb is not get up or down?
The switch is not working? I don't know what is the problem in it? pls help me
Thank you
Hello friends,
I am generating pwm signal in CCP1CON and CCP2CON of PIC16F877A controller and also i connected two led's across the pin with resistor's. I am getting output in the oscilloscope but the led's are blinking, why the led's are blinking?
How should i rectify the blinking of...
Thanks for your reply Sunnyskyguy,
My circuit diagram itself contains the required information.
Did you cross checked my code?
Flickering occurs in the range below 0-70% after that there is no flickering from 70-100%.
Triac is A1A2G.
Hello friends,
I am doing one simple project which controls the brightness of the bulb, I have PIC16F877A micro-controller,MOC3031 in-build zero crossing detector,bulb i am using is 25 watt,Triac,LED,Alternator.
I am using 120Hz for the bulb(PWM) and the device operating frequency is...
Thanks for your reply Horace1,
Ya, i gave 8MHz crystal frequency for each boards. Ya, i have received led signal in the RX for first time then it is not responding with the switch(TX). No, i did not checked with the pc with explorer board.
No i don't have oscilloscope.
waiting for your reply
Hello friends,
I am new to this pic24fj128ga010 controller. In my project i want to use two pic24fj128ga010 controllers at a same time using UART communication. I have two Explorer 16 Boards, For Example i have taken that 1st board as Transmitter and 2nd board as Receiver. In the...
Hi friends,
In my project i am using pic24fj128ga010 controller in explorer 16 board,
I have two set of explorer 16 board with same controller,
I want to connect two explorer 16 board using UART communication.
And also i am using MPLABX IDE and XC16 compiler.
Aim of my project is to...
