1. i'm doing programming for keypad 4x4 with pic16f877 (PIC C compiler) but the problem is the character that i enter did'nt appear on the lcd. the lcd also got few problems...sometimes it's function well as programmed but few minutes after that strange characters appeared...does anyone know...
hi everyone....
i'm doing my project in dc motor drive with fuzzy controller..could anybody help me with this. specially with the programming part that related to fuzzy controller. i'm using pic c language. ....it's really make me fuzzy right now....
thanks in advance...:D
positioner dc motor
actually i have problem with programming part...i'm using c language (micro C compiler..etc...)... i think i'm stuck at the motor feedback part...does anyone know any sites that could help me with this problems...or any ideas from any members...anyway...everyone...thank you...
optical encoders with pic16f877a
Currently I’m doing a project by using a PIC microcontroller 16F877a series to control a DC motor (angular position). the shaft of motor is connected to potentiometer as position sensor. the input is entered by user (keypad). Can anyone help me on this?
Hi
I would like to ask about 4*4 keypad board; its circuit connection to PIC.
the keypad has 10 pins on the bottom. The problem is, i am not sure which pins are assigned as columns, and which pins are the rows? i already upload the figure just like my keypad.
thank you in advance.
stepper motor driver 16f627
hi. i need some help here.
is there any method (using pic 16f877a) to control the degree a motor rotates by controllling the voltage supplied to the motor?
thank you in advance.
pic 877 serial
can these 2 PIC communicate? if can, how is the pin should be connected because i didn't find any Rx or Tx pin on these two.
i'm going to tun a dc motor controlled by pic16f84A, and i found it does not have a built-in pwm function. can anybody help me with the source code to run...
irf540 bridge dc motor
hi
does anybody know the c source code of PIC program on how to control the motor using H bridge? the PIC i'll be using is PIC 16f84A
tq.
89s52 serial communication
mm.. i mean where should i put resistors and whatsoever on 2051? or, do i only need Connect pin 10 (89C52 Rx) with pin 3 (2052 Tx) and pin 11 (89C52 Tx) with pin 2 (89C2051 Rx) and of course 0V - pin 20 (89C52) and 10 (89C2051) as you've mentioned?
because when i did...
89c52 serial
I've started a simple program on serial interface between two AT89c52 as a practice for serial programming
But, i need to interface AT89c52 and AT89c2051.. But i don't know about their circuitry connection
Could you please help me with a circuit diagram on it?
thank you!
hi
anyone can help me to understand better on dc gear motor?
actually i'm working on intelligent entrance systems project
and i don't know how to set the circuitry with the gate
sorry if just post in the wrong topic
thank you
