I realized the internal clock 8Mhz is same but not stable. each had few percent of error, eg. if I need 104 us of delay, i have to give 116 in the __delay_ms(116) function. it is difficult to implement without external cloak or crystal oscillator. since 104us for each bit in 9600 baud rate...
you would try like # for mode operation, where in normal operation # is not used, if # key is pressed, you go into another subroutine where multifunction operation can me done, here you can use same pin for multiple purpose operation. and you must activate fault key press system, where you upon...
HI guys,
I am using 12f617 uC with internal oscillator with 8Mhz, I programmed three ICs with the same code all hardware are same, but among the three IC only one is working fine and other too was not giving expected output. This code is sample library which i developed for main project. All the...
Yes, There is no copies, just the pointers.
And Thanks your support I was able to proceed this. :)
As you can see the code in the function 'fun' and 'fun_one' both of their return type is pointer pointing the location of the value.
as you can see in the 'printf' statement, those function are...
HAHAHA.... its one of the strange code. Well lets not consider this as application oriented rather let us think why this code operates such way. I guess you guys might try to solve and came to output must be 'ThomasMike'. but its output is different. i am curious to know how it works.
Yes, @KlausST , its for learning purpose for the understanding of pointer and structure.

Its PCB mount metallic core single phase transformer of 200mA stepped down to 18V, its size is 22x38 and, its distance between uC and transformer is hardly 3mm. and there are relays too in the design.
hi,
My PCB size is compact and so i am placing the microcontroller AT89S52 near the transformer, I am worried about its working. I want to know will this design will disrupt the normal working of the microcontroller? Kindly give your valuable feedback.
yes.. i got to this point and got stuck. it would be great help if i get little push in this .. I have attached the both ide settings below.
Please look into it, if any clue you get kindly help me to understand.
