Hi! Dharmani,

this is Michael!
i was looking to your web and i found what i m looking for,
i m trying to save captured frame from a camera device to the 256K EEPROM,the cam frequency is 13.5MHZ and in your code you didn't mentioned anything about the TWI frequency neither you imported the ,please leave a reply on mickel-haddad@hotmail.com,

thanks in advance,

Michael .

I am new to the world of AVR Microcomputer programming. I like your project very much and would like to build one of my own. I have downloaded your code and a copy of ImageCraft, Release 8.05 rev 02, but I am having a problem building the project using this tool. I am getting the following error and warning messages. Any help you can give me to resolve these issues would be greatly appreciated.

Hi
first excuse me because my english grammar is not good enough.
I see your nice project on http://www.dharmanitech.com/2011/05/microsd-atmega32-datalogger.html and now I'm very glad too find you.
I need a project like this for my school with avr codevision and 2 diferrences :

1 - I want to use an srf02 sonar module and log the distance + 2 ADC ports for voltage logging.

2 - I want the datasheet of microSD module to make the that in my home for my project.because in my country this module was not available.or if there is a way to connect the micro SD or SD directly to atmega32 can you tell me that ?

it's urgent .
thanks

2012-05-07T07:55:19.145-07:00

I am not using the MICROSD module and microsd module connector but instead of that I am using Microsd adapter with memory card. I have
soldered pins on microsd adapter and have fixed it on the Bredboard. Then I have wired it with ATMEGA32 according as shown in the circuit diagram of the datalogger. Will in that way the memory card cannot be accessed by the microcontroller. Please have your suggestions.

Myself Sumanta is facing a problem with storing data in microsd card through the adapter. I have not used Microsd module connector but has fixed the microsd adapter in the bredboard with wires soldered on it. I have done all the connections as they are in the circuit diagram of the datasheet. But after powering on the red LED is blinking and nothing is displayed into Hyperterminal. Can anyone please help me to sort out the problem.

I found next issue. Code removes at least one cluster from free memory record even if you append one byte to the free space of last sector of existing file.
Do I do something wrong or you have fix for this bug?

2012-04-24T01:52:14.605-07:00

I make some changes for reading ADC channels:
1 chanel temp
3 channels 0-5V
4 channels 0-30V

I make some changes in main.c ADC_routines.c ADC_routines.h files.

ADC_routines.h

I add just this line :

void readVoltage_b(unsigned char);

ADC_routines.c

In this file I add this :

void readVoltage_b(unsigned char channel)
{
unsigned int value;
float volt;

ADMUX = 0x40 | channel;
value = ADC_read();

volt = (float)(value * 5.0)/ 1024.0;
value = (unsigned int)(volt * 100)*6;

voltage[6] = 'V'; //V for voltage
voltage[5] = ' ';
voltage[4] = (value % 10) | 0x30;
value = value / 10;
voltage[3] = (value % 10) | 0x30;
voltage[2] = '.';
value = value / 10;
voltage[1] = (value % 10) | 0x30;
value = value / 10;
voltage[0] = value | 0x30;
}

main.c

In this file I add and change this (I marked red) :

for(i=0; i<10; i++) dataString[i] = date[i];
dataString[i++] = ',';

for(j=0;j<8; j++) dataString[i++] = time[j];
dataString[i++] = ',';

readTemperature(0); //read temperature from adc channel-0
for(j=0;j<7; j++) dataString[i++] = temperature[j];

for(channel=1; channel<4; channel++) //read voltages from ADC channel 1 to 3
{
dataString[i++] = ',';
readVoltage(channel);
for(j=0;j<7; j++) dataString[i++] = voltage[j];
}

for(channel=4; channel<8; channel++) //read voltages from ADC channel 4 to 7
{
dataString[i++] = ',';
readVoltage_b(channel);
for(j=0;j<7; j++) dataString[i++] = voltage[j];
}

dataString[i++] = '\r';
dataString[i] = '\n'; //always end the string with these two characters,
//before calling the writeFile function

Can You verify that code is OK ?

I didnt built this project for now, but I awaiting ATMega32 in TQFP44, I dont have where to try to see if it works or not sorry.

Pins connection with SD card are :

ATMega32 pin 8 to SD card SCK,

ATMega32 pin 6 to SD card MOSI (DI),
ATMega32 pin 5 to SD card SS (chip select CS),
ATMega32 pin 4 to SD card ???

I dont know where go ATMega32 pin 4.

Is it possible to make logger channels like this :

Date

Time

2 Temp (In & Out)

3 Voltage 0-20V for voltage

3 Voltage 0-5V for amperage (up to 5V for current shunt)
