Hi, I have a PC89c66 chip to program. i was advised to use philips winISP. However, my PC does not have a serial port. although i used a parallel2serial adapter, the software can't recognise the card as it expects a COMM port. any workaround...

hello guys. I am write code in the matlab connect about IC89C51 by MAX RS232. but i don't know when we use matlab signal of IC89C51 as command?? code demo: com = serial('COM1'); set(com,'baudrate',1200); com.DataBits =8; ...

Hi to all, Can any suggest me how to generate PWM using PCA in MPC52G516A microcontroller. I execute below program but i unable to get the output at port pin P1.3. #include <reg_mpc82g516.h> #include <stdio.h> void main() {

Hai binu_ji i have one doubt in keil software,that is; if we compile c program the code location is jumped to 0800[debug view]even it is a small pgm [68 byte size],but i want to insert all my c codings[for simple program] with in...

i got an timer program from 8051.com http://www.8052.com/codelib project: "16*2 LCD display based Pulse Counter" and tested it in Proteus. it's works but the seconds counting till 89 then increment the minutes by 1!! how i can modify the...

hi everyone.. i´m doing a project where i need count the signal time is logic 0, in a determined period of time! need to compute the sum of T during 100ms

hello masters..!! 'm luking out for sample embedded c codes for pwm generation usin P89V51RD2 in high speed output mode.. plz help me with the same and if possible do provide me the comments so dat i can understan dem pretty soon..!!!

SIR, Plz send me the equipment required for finger print based security system through mail id it urgent. value of resistance,cap,relayand every thing

Dear Sir, I wanted to build digital code lock project. But instead of using AT89C2051 i used AT89S51 as its available in our area. But after building the device using AT89S51 nothing happens. I simulate the project with proteus 7 its works fine...

Heya, I was reading the book: 8051 micrcontrollers, authir david calcutt and i am not sure about my understanding to section 1.8: Microcontroller clock. The author gave this code $INCLUDE (REG66X.INC) ; lists all sfr addresses ...
