Connect 1GB Memory Card to Hyperterminal

Hello
I am using p89v51rd2 which supports spi..
can anyone give me the ckt required to connect my sd card to hyperterminal through max232..
i have dbts in that how to connect?
do i connect my card to my 89v51rd2 and then muc to hyperterminal?
can someone help with the ckt using p89v51rd2

Hi Darpan,

I attached a simple schematic regarding the interface.
I hope it will help

Good Luck

Hello Neil,
Is it okay if i give 5v supply to sd card, because it needs 3.3v..
thanks for the help

Yes, but it will shorten the life span of the device.

Hello Neil
I did that circuit which you had suggested me..
But the hyperterminal is not responding..
Do i need to burn my microcontroller and what clock freq the 1gb memory card should get to work?
which mode should i choose in spi

thanks for the help

Hi Darpan,

Yes, You need to burn it if the microcontroller (or AVR) is not yet set to read with SD cards. It is the same with microcontrollers that are available in the market. SD cards can run from 0 to 25MHz. I will attached a design circuit with the microcontroller and SD card interface.

In case you want to verify if the hyperterminal is not really responding, try to short pin 2 and pin 3 of the rs232 port or D9 connector. This will produce data character on the hyperterminal screen if the hyperterminal is really working.

You can also try other Terminal Programs and Compilers that are designed to program microcontrollers such uVision 3 and Flash Magic.

Good Luck

This is the designed circuit for Microcontroller+ISP+SD Card interface. I hope it will help.

Hello neil,
i dont know what that isp programmer is..but i have a development board whyich has on board burning facilities.
i had connected miso mosi clk and cs lines of my controller to the card.following is the code which i burnt in my controller, still the hyperterminal is nt responding..
#define ss_pin P1_4

void spi_config_master()
{
ss_pin=0;
SPCR=0X50;
SPSR=0X00;
SPDAT=0X00;
}


void main()
{

P0=0XFF;
P1=0xFF;
P3=0XFF;
P2=0XFF;

spi_config_master();
}
Thanks

This is the code which i have burned in my controller..
Thanks

test...

Hi Darpan,

In case you have tried the second statement above:
" try to short pin 2 and pin 3 of the rs232 port or D9 connector. This will produce data character on the hyperterminal screen if the hyperterminal is really working."

Then try 3rd statement above:
"try other Terminal Programs and Compilers that are designed to program microcontrollers such uVision 3 and Flash Magic."

By the way, HyperTerminal has many problems that is why they are not on windows Vista and windows 7.

I recommend try other Terminal Programs that are available on the net.

Good Luck
