My pic12F1840 + 12C LCD tachometer using IOC feature This is the first time I used IOC feature. Maybe the code is not correct. Maybe there is unwanted interrupt firing. If anybody finds such thing in my code then tell me how to fix it. Code written in mikroC PRO pic 6.4.0 Compiler.
Constant display of 3000 RPM seems to indicate 50 Hz hum but no tachometer signal at the counter input. Looks like a hardware problem.
So I constructed this tachometer project (it can measure RPM using 3 methods but I just chose one of them which is by IR LED and Photodiode) and I'm really sure that I did it right according to the circuits schematic I got from an electronics magazine, but when I connect the power supply its just dead and nothing works at all, please look at both c
I've done some readings on how tachometers (as in automobile tachometers used to measure engine RPM) works. Apparently modern tachometers drive the needle from the signal received from its signal wire; which is a series of square wave pulses. If I'm not mistaken the frequency determines what RPM the engine is running. So as a holiday project (...)
Hi I am new to microcontrollers and am trying to build a tachometer using the pic 16f690 with a reed switch and LCD display. I am having some difficulties trying to calculate the RPM of a shaft using one magnet and one reed switch. Any suggestion of how to write a program in assembly code to calculate the RPMs? I want the readouts to be valid be
The following thread discusses implementation of a pic based tachometer using various sensors in great detail: some questions motor speed monitoring I would suggest reviewing the thread and posting any further questions you may have concerning the implementation of your tachometer. BigDog
Here is a fairly in-depth discussion on the design of a tachometer with source code and schematics: some questions motor speed monitoring You find may example tachometer projects listed in this discussion thread as well. BigDog
Hi , could you help me please to understand the assembly code of this LCD tachometer with pic 16F628 for example I don't undersand the use of blades and how it works ?
I have chosen to work on a small project - a DC motor controller - with the objective of building a tachometer with a pic MCU. But I have never designed with a DC motor before, and so I have no idea what the current (milliamps) and voltage that they can handle (max and normal operation). Can someone help? I have attached a picture of the (...)
Hi every body ! i have a project with 8051 . I want to design a tachometer . Many people use pic or avr but with me , i'm a newbie so i start learning MC with 89s52 and use assembly for programing . Program button and lcd is so so ! But i have trouble with counter in 8051 . Please show me how to count pulses in 1s -> pulses in 60s (1 minute) and ho
HI IM DOING A PROJECT WITH pic 16F84, IM TRYING TO MAKE A DIGITAL tachometer WITH A 2X16 LCD AND THAT CAN GIVE ME RPM AND RPS BY ACTIVATING IT WITH A DIPSWITCH AND USING AN OPTO BUT I HAVE NO IDEA HOW TO DO IT. COULD ANYONE HELP ME PLEASE
I Looking for help on conditioning the signal comming from the positive side of a coil on a harley motorcycle.I want to use it with a 4n25 opto for a rpm gauge with a pic processor.Thanks in advance.
Hello, This is my first post to this forum, so bear with me. I'm working on writing assembly code for a R/C microturbine tachometer. I'm very new to this so, I really could use some help. I'm using the pic 16F84A micro controller chip, compling the language with MPLAb IDE v 7.30 and assembling the data with Mplasm. I'm having a problem displayi
hi I'm also thinking about making a tachometer, but with a different approach. I would stick a ferromagnetic, kinda circle, to the rotating shaft, with one 'cut' into it. on one side of the circle put a small magnet, and on the other side a Hall sensor. The hall sensor would give u a nice pulse you can measure with a pic microcontroller for exampl
