Egypt. Activity points. 5,880. AA, How to connect the Bit RA4 in port A in 16f84A in order to use it as a data i/o pin? As I understand from the data sheet, when it is programmed as o/p & the bit no 4 in port A is 0, it is connected to ground. when it is one it is floating? I want to use it as o/p pin & toggle the o/p . Regards, Amr Ali.

Hi all, I am a total newbie to Arduinos and could really do with some expert guidance. I have a project built on the 16F84 PIC. To alter any of the user variables, I have to alter the programme code using my PC and download the amendments into the PIC (using the programme PicKit2) and a hardware PIC programmer (iCP01-V1) which is …
The link is to a video of my "Rube Goldberg" 16F84A "development board" with a plug-in daughter board that contains 13 LED's being driven by the 16F84A in a back and forth chaser pattern. Twelve of the LED's are being driven by 2N2222A switches on the daughter board. The other LED is connected to a 2N2222A on the development board …

Gud day!! Thanks 4 the reply you send last time... can I ask about the 16F84 microcontroller and its available uses in electronics for our project.. Thank youvery much hope you can help me this...
Re:PIC 16F84A Working in Simulation, Not working with actual chip Saturday, January 21, 2012 8:13 AM ( permalink ) 0. I suspect your problem was due to your Melabs programmer settings overriding the configuration set in the HEX file from MPLAB. If you don't fix the problem you will have a HARD time with the PIC16F88.
In fact the 16F88 is a good PIC micro to progress onto after starting out on the 16F84 as the 16F88 is backwards compatible with the 16F84 -it has the same number of pins and same pin functions. Some pins are more flexible but still backwards compatible with the 16F84. Note: You can't easily go from a 16F88 back to a 16F84A, as the 16F88 lets ...

The PIC16F84A has one 8-bit free-running timer named TMR0. The term "free-running" means it continually runs in the background and has no start or stop control. You can read or write values from/to this timer. Since it's an 8-bit timer, the TMR0 can count from 0 to 255 (2 8 = 256). Other microcontrollers have multiple timers with higher bit ...
Jun 3, 2012. #3. The code was originally used to program a 16f84A that the author then sent to me. It worked, but eventually went faulty, hence the need to program a new one.

It's called Silent Alarm. It's one of my early projects implementing my favorite Microcontroller Microchip PIC 16F84A. I wanted to make a silent alarm that awakens the human in gentle and quite way. I wanted to try the vibration motor used in mobile phones. Using Seven Segment Displays to display the time and alarm.
