we are working on a simple system call program creating 5 child processes using fork from only single parent process, the code is working but with some exceptions . We are waiting the parent in signal handler of SIGCHLD, and checking whther the child is exited but , in our code it is not exiting...
i want to know if we can make a graphics processor work as a cpu in a system by giving some additional hardware and if we can install some operating system on it with some memory support. Is it possible !!?.
i need to program a 89s52 to measure the length of thread , the thread moves over a circular goddet over which a proximity sensor is installed on the backside, when goddet rotates sensor senses and the 89s52 counts pulses.
i am trying to use a RTC1307 for a specific time like(5seconds) and...
specifications i meant , whether it gives a high voltage on detection or change in current, bcoz both will have different assemblies , u can scan the port as input to which it is connected and accordingly change pwm count and operate the motors
for controlling any ac motor you need an SCR arrangement in anti parallel , for 3-phase you will need 3 sets of it then you can control the motor using an moc which is connected to the controller , moc is optical device it is used to trigger SCR, the duty cycle ac voltage can be controlled by...
hi bro i found my RF module transmitting from the controller and i recieved data on the pc but its not working the other way i m not recieving the data on the controller , my pc is transmitting correctly and recieving also , is there any different way i should recieve the data or the normal way...
sychronous circuits are provided with same clock and all the circuits work at each clock pulse synchronously.Whereas asynchronous circuits are provided with clock pulse for only first stage next stage depends on the o/p of first and so on.refer digital design by morris mano
serial0 interrupt 4 is the serial interrupt subroutine ,the interrupt is called but data for LCD is not taken and also the interrupt flag is reseted in recieve_data and send_data() functions from their the lcddata() function is called.
hi beyondH i recall i also faced same problem even when i only recieved data in interrupt and then displayed it in main program i also got random display so if u go through my previous program u would find i used interrupt but i reseted RI and TI i main program hence i got data on LCD
whether cdac exam is in stages or one exam and interview first cet is on 19 nov and second on 10 dec i want to know whether both r to be appeared or anyone would do.
