I need help with TEC controller based on pic or any other microcontroller.
Hi All, I am looking for POCSAG encoder based on pic processor. I need to know any more about POCSAG protocol. How I can control 10-15 receivers. Any software ? Any ideas ? Thanks, Pioneer_007
Hello all, I'm searching for a 1Hz to 100Hz frequency meter based on pic16F877 or pic16F84 for measuring Mains Frequency. I've already searched for the same but ended with 50Mhz frequency which gives error when measuring lower frequencies of 1 to 100 Hz. Any advice/links will be appreciated.
Where I can find an examples of using interrupt (including the header) for ADC on pic?
Okay, okay, people have been so negative as to the idea of a pic playing MP3 files (even just 8kbps) so I have thought of an idea. How about a pic playing WAV files? When I get my pic interfaced to a HDD, then I'll be able to play WAV files. I won't have a file system, but instead lists of bytes with data. So, any idea as to how to play (...)
did anyone tried to run somehow code from RAM on pic? i made it with motorola HC08 micrcontrollers - that have Von Neumann's architecture making easy to jump from code space to data space with loaded program, but pic are Harward architecture based with separate data and code spaces. my idea is to load a little piece of code from outside to RAM an
hi all here i find a good tutorial on pic MCU,hope it might be useful. regards john
where can i get help on pic 18f452 other than datasheets provided by anybody out there who can help me out........
I am not sure yet, but it seems that BCF and BSF instructions on pic 18F series behave very odd when a PORT is set to input mode. For example, if you do this: MOVLW 255 MOVWF TRISB BCF PORTB, 0 BSF PORTB, 1 then it seems there is no effect when using those instructions. However, if you do this: MOVLW 255 MOVWF TRISB MOVLW 2

can anyone help me? I've got a problem with the code I'm working on. For a while it was kicking out of the program when RA0 and RA1 were both low. I've played with it and now when RA0 and RA1 are low, it runs a bit then gives me a stack overflow error on pic Simulator IDE. Where am I going wrong?? Oh, and that bit at the beginning with errorlevel t

hi i made a little project based on pic 16f8777a to convert a analog pot movement (from zero to 5v) to binary value on 8 led attached to portd. Everything works pretty fine and i want to do a modification that when i rotate the pot the led lights up linearly like a progress bar. i use assembler to write my program and i use proteus to simulate
Guys, How can I reduce 16 counter on pic assembler ? I've done this code but only reducing the low part of the counter, it didn't reduce the high part, how can I reduce all of them ? What do I miss here ? any helps will be appreciated, thanks movf LedTimer,w ;for every 10 counts btfss ST

Hello , Somebody can share information about how to make a interface based on pic microcontroller to drive a hard disk. I want record B/W video to hard disk. Any information is appreciated. Regards Garfield :roll:
I used to program pic's in circuit with good old Tait Serial programmer connected to parallel port and using ICProg1.05a. This seems not to work with Xp/AMD2200. So, I'm looking for a SMALL design which can program pic's in circuit and also works with Icprog and Xp. It should be a reliable programmer. Don't like JDM, cause it doesn't progra
Hi guys. I have a problem with my first pic micro. I use pic18c801 with an external EPROM. And after switching on the power supply, signal OE (output enable) of the micro is high. And it never goes low to read a code from a eprom. What can I do? I really need help!!! Best regads

hello nid some. I am usin a sensor lm35 to measure temperature and feeding this to a pic 16f872 thru RA0 which is an A/D port. Is it ok if i directly input the voltage from the sensor to the pic. The voltage is in mV e.g a temperature of 26 degrees gives a voltage of 260mV. Am tryin to avoid an amplifier. Also if someone can help me with the n

Hello, First time poster here. I am currently working on a side project and would like to develop an IR remote control transmitter and receiver. I would like to have 3 or 4 channels (momentary on-off) using a Microchip pic (probably 16F). The output of the receiver would probably go into another pic or CPLD. I would also lik
Hi All, I am working on a project which need to make the pic microcontroller acts like an ANN. I decided to choose the pic18F452. The ANN (backpropagation/Multi-Layer Perceptron) was train first using MATLAB. After that, the input and output weights obtained from the MATLAB will be used in the microcontroller. However, since there is not enough
