Hi guys
first of all very much sorry for the late reply.
and I would like to thanks marce and other who has replied to my this post and for the link which marce shared here.
That link is very precious link which I think would not be able to get easily via the google search.
but here I am...
Hi guys
I want to know the basics of power supply design and want to know the topics required for the design of the power supply of this level.
Specs are :
Input Voltage = 230 V AC.
Output voltage = 5V DC.
Output current = 40 A DC current.
Power = 200 Watt.

hi guys
I have been looking and studying for the SMPS power supply design for the 5V 60 Amp rating i.e. of 300 W so that at full load it must give a current output of 60 Amp.
Actually I have looked all over the internet but not able to find the appropriate resource in this regard.
Actually I...
Hi guys
I want to sell Atmega 16 Development Boards with
following specs:
2 Uart ports (One for direct interfacing to the UsbAsp programmer).
8x3 IO port connecters.
8x1 ADC interfacing connectors.
Stable regulated on board power supply.
Power Supply provisions :
The Board can be powered...
Hi Guys
I am facing a very serious problem in case of GSM.
Actually I have DTMF receiver of HOLTEK named HT9170 which I have interfaced with the GSM module named AT139D from the ATWIN company.
The interfacing is as follows :
The SPK+ pin of the AT139 has been interfaced with the pin 2...
Hi Willis
Thanks for replying , I am using the latest version 1.20 available on the microchip site.
and in regard to this problem I must have mentioned before that I checked the results on both the MPLAB v 8.86 and MPLABX IDE and have got the same result in both IDE.
So it's not the IDE...
Hello guys
I am using MPLABX IDE with the HiTech C compiler v 9.83 and I compiled my source code in it, basically I build it .
So in the memory summary in the build option I got something different and in the memory view graphical dispaly in the MPLABX IDE I got something different output of...
Hello guys
I am using the MPLABX IDE v 1.20 and the HiTech compiler v 9.83 for the pic microcontroller pic16f1526 and I am compiling my code but I am getting the following error:
CLEAN SUCCESSFUL (total time: 290ms)
make -f nbproject/Makefile-default.mk SUBPROJECTS= .build-conf
make[1]...
Hi brass
I tried your option and included the inbuilt function of the pic.h but the following error comes out and it's not working:
"C:\Program Files\HI-TECH Software\PICC\9.83\bin\picc.exe" --pass1 I:/flash_program.X/flash_test.c -q --chip=16F1526 -P...
Hi BtBass
First of all thanks for your reply.
I have seen the pic.h file but there is no source code for the reading and writing of the flash memory only the functions have been defined but here I want to make my own functions in order to read and write the flash memory but the problem which...
Hi guys
I studied the memory specification of the pic16f1526 microcontroller , it only has the Flash memory and not the EEPROM memory and therefore I need to utilise the flash memory for the storing of the data .
Actually what I want to know alongwith the c code to read and write to the flash...
Hi guys
I am programming on the pic16f1526 micrcontrolller with the hi tech 9.83 compiler .
Here I want to read and write data in the flash memory of the PIC microcontroller, ans for that I have written the following function so can you guys please check my this code and can tell me that how...
Hi guys
I am using the pic16f1508 microcontroller in which due to shortage of the pins on the pic microcontroller and abundance of peripherals I have used the programming pins also for the general purpose .
So want to check that whether it is not going to create any problem with the ICSP...
Hello FVM
you are right and that whats I am doing as I said that the second circuit regarding the tl431 regulator in which the V25REF value has been taken can be used as the refrence purpose as it would be stable one.
and in the first since it is grounded to the analog ground therefore it is...
Hello guys
I have two questions one is regarding the TL431 and the other is regarding the OPAMP .
My first question is that I want to get the refrence voltage of 2.5 volts from the TL431 but in the datasheet it is given that it can be regulated to any value from 2.6 to 36 V so can't I get the...
