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'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 (...)
Please upload the schematic files which are missing from The archive only has asm and pcb pdf's there is no schematic. Digital tachometer by silicon chip mag. It is what i wanted....
m designing a tachometer and and a sms controller using 16f877 and i want the coding in C can anyone help me???? Added after 5 minutes: and i want to display the RPM on the 16x2 LCD
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
More data please What kind of tachometer? What kind of servo? position or speed? I used a washing machine motor with AC tacho for speed servo ; controling high speed in 5000 -13000 rpm range with uc3843 ,no micro.
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
Proposed schema: 1. Input signal from sensor in pic 2. start internal timer of pic 3. count pulses for a specific time 4. calculate speed My problem also in how to start the internal time of the pic. The following thread discusses at great length the implementation of a tachometer using a pic and (...)
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
You might benefit from review the following detailed discussion thread concerning the implementation of a tachometer using a pic: some questions motor RPM monitoring It is a similar task, counting the number pulses in a specific time frame. BigDog
Constant display of 3000 RPM seems to indicate 50 Hz hum but no tachometer signal at the counter input. Looks like a hardware problem.
Has anybody seen a pic routine for PPM ? Any info greatfully recieved. Schmitt :smile: :smile: :smile: :smile:
I have tried sereral Basiccompilers for the pic. Most compilers had bugs..or compile very large sode for simply instructions... Anyone know what's a good
Need information how to make the pic circuit with connector to an programmer. Programming should work even if the pic circuit has power switched on. But should also be possible if the power of the pic board is not availabel. I already have good info on programmer. Any one has a proven circuit design that works well?
I'm looking for a simple PWM low voltage (6/12V 50W) lamp controller, using pic 16F84/F628 or 12C509 and a power MOSFET. It should provide "soft start" and regulate the lamp voltage from a battery V greater or equal the nominal Vlamp. Does anyone has already it or I have start this design from scratch ? T.I.A.
what is the best language to program with and is it proprietary to microchip? what tools should I use ? Is the Mplab ide suitable and is it complete? Debugger or emulator or both? Any help is greatly appreciated. thanx
i uploaded some pic programmer schematics that i found from some sites i wish they will be usefull for you. fm/digitallan/pic digi...
Hi, Where I can find definitions to build an interface for a curent loop (4-20 mA) and a pic micro? ThX NeuralC
Hi folks! I realy nead a schematic and a hex code for building a circuit with a pic to measure the pulses came from A & B channels of a TACHO generator and display them in a possitive ora negative direction. I need this circuit for testing high precision SERVO motors. Thanks in advance John
Here is a nice guide to pic: alots of example and progs. pic Happy New Year :smile:
Dear friends Here is a interesting project to build a pic to emulate the responses of a Sony CD MultiChanger, so that the Phono/RCA's on the rear on Sony head units can be used for a portable CD or MP3 player. hsmpt

I need this program. Who can hel me?.Thank
The latest issue of circuit Cellar has an artical on using a pic to send and receive SMS using an Ericsson phone. It is explained easily and simply, even I understood it first go. I have uploaded the artical and software to FM1 directory BobP Have fun....
ANybody have built a bitscope before, they give instructions for you to built from scratch bit refused to disclose the PLD and pic source codes. THey made you purchased those chips, that's sucks.. Anybody have the source codes for that? thanks in advance
Hi all, I'm trying to simulate a program with a pic->PC communication. For that I use Pro**Teus with the VTERM module connected to the RX/TX of the 16F870 USART. For error checking I'm using the 9th bit of the usart to send the EVEN parity bit. After simulate on MPLAB I see that the bit TX9D(9th bit) is correctly set (When we need it to get E
