Hi,
I need your piece of advice. I am kind of novice to programming C. I am trying to create a Generic LCD_printf function, that can print decimals, string, characters.
The following is the code i am trying
#include <all necessary h file>
// declaration
void lcd_printf (const char *,...)...
Hi jayanth,
Based on your point, I think i got the solution to my problem
unsigned long data1 = 0xFF000000;
unsigned char shift = 0xA0;
data1 = _lrol_(data1,8);
data1 = data1 & 0xFFFFFF00;
data1 = data1 + shift;
Thank you for enlightening me about unsigned... i forgot about it...
Hi,
please look into this code
#include "REG52.h"
#include "intrins.h"
void main()
{
long int data1 = 0xFF000000;
char shift = 0xA0;
data1 = _lrol_(data1,8);
data1 = data1 & 0xFFFFFF00;
data1 = data1 + shift;
}
the value of data1 i expect is 0x000000A0, but when i execute...
What will happen if, In a DC generator,the resistance of the field winding is increased??
will it increase the output voltage or will not affect it at all ?? :?:
Thank you for your reply!!
i liked the idea for desiging a DC DC convertor with a 555 timer.. this can give me a cost effective idea.. i will try this..
"If you add a 12 volts regulator you need to raise the input voltage by 2 volts from the output which means you have to have 14 volts minimum...
Battery voltage regulated power supply with positive and negative output
I would like to design a cost effiecient and effective voltage regulated power supply, such that i can have +12V and -12V output.
But the challenge is that i am going to use a +12V Battery as source [No AC source].Well my...
Hi Arungokul,
i guess i can understand your question. but let me confirm, you are trying to display Hex value of '0x5A' in the LCD dispaly [through ASCII Character]?
If yes, well the following steps might help you [we will take example 0x5A to be displayed in LCD]
- seperate '5' and 'A' from...

Hello,
I want to build a ckt with voice Playback with Dspic30f Series uC.
Can anyone advice me which is cheapest Dspic30f series to desgin.
I am not sure whether Dspic 30F4011 will work for voice interface.
I guess we need some Codec for interfacing.
I am confused :(

Re: A JPEG FILE IN MMC
Hi,
Actually i am using a Finger print sensor. to get the binary images of the finger print. my aim is to store this image of a finger print in a MMC card.
I can use a Dsp processor to make a jpeg file from sensor.
Now i have to use this send data from Dsp processor to...
Hi all,

Hi,
Thanks a lot. That worked. I never expected it to be so easy.
But i wonder what would be the Difference between a FT232RL and FT245BM.

gprs interface
Hi,
Nowadays all microcontrollers come with internal serial port or USART. The GSM modem also communicates using serial port.
So the connection would be
8052(inbuilt USART) ----->GSM modem
Now, program the microcontroller to send all AT commands, through the serial port...
vnc1l-pic16f688 spi example
Hi,
Thanks for your suggestion. i went through the document. it seems it will satisfy my requirement.
But unfortunately , i have bought ft232rl IC . so i have to use it (or else my boss will kick me out). So can you tell me whether i can use the IC for connecting...
