Hello Everyone !
I am trying to make POV clock. I have previously build POV display using pic16f84a with 8 LEDs. In that project i dont have synchronization between motor and display timings. i just added fixed delay to display text and changed motor speed with variable potentiometer...
Hi everyone!
i currently want to develop a bipolor stepper motor driver using a microcontroller and L298 IC.
in past, i have developed microstepping driver using NXP89v51RD2 microcontroller and 4 TIP122 for unipolor motor. the firmware has a look-up table for 1/8 microstepping, 4 PWM signals...

Hi everyone,
Currently i am working on a hobby project ("propeller clock"). i want to add around 30 or more leds which is directly controlled by GPIO pins of microcontroller. so for that purpose could use 32-bit arm cortax based microcontroller. (i am familleir with pic/avr/arm).
when i went...
I also noticed one thing, that when i measure voltage on crystal oscillator pins are 1.45 v and 0 v ,when microcontroller PCB is alone.
When i atteched ICSP cable from microcontroller PCB to PicPgm USB programmer. the Voltage becomes zero on both crystal Pins.
What is Wrong ?
Please Reply.
Thanks for Reply to Both !
I have connected 10uF capacitor between VDDcore and GND. and Voltage on this pin is 2.74 V.
I think it is OK as per above document.
How much is it easy to asssemble PICkit2 ? is it more reliable than PicPgm Ckt ? are there less chances for errors in case of PICkit2 ...
Hello Everyone !
I need to program PIC18F24J11 ic. so, I have made Picpgm USB programmer and it has been detected by PicPgm.:-)
The Staus Bar Indicates Picpgm USB programmer and USB(FT245B).
But There is "No pic Connected" error. My PIC ic doesn't detected by Picpgm.:cry:
I have Checked All...
Thanks both of you for reply.
@shaiko
Thanks for your suggestion.i would go for altera.
i want to use CPLD, because my budget is low.(FPGA dev kits have very high price (starts with 10,000 Rs i think))
CPLD have different packages, it can be easily mounted to pcb

Thanks for your...
Hello Everyone !
I currently working on a project of hobby cnc mill. i want to design custom control panel to operate the machine in this way :
-> panel have a graphical lcd , buttons etc connected to microcontroller which handles user interaction.
-> cpld is used to control motion of stepper...
Hello every one !
I am currently working on a project which require to generate Xy2-100 protocol for Laser galvo systems.
the protocol should be implemented on ARM7 microcontroller which generates XY2-100 protocol signals.
But although it is industrial standard, i cant find any detailed...
hi !
i am new to keil ...
currenly , i am working on p89v51 to enable the spi mode and use it with sd card...
my problem is i cant get output on port 1 pins (ss,mosi,miso,sck)
#include <stdio.h>
#include <p89v51rd2.h>
void spi_init()
