Sorry this is a typo. It should be
char pass[10];
I think this is what I need.
Can you please recommend any good book for this. It seems that most of my problems are syntax related.
Thanks.
Hi Everyone,
I made an MCU-based webserver using ATmega328-PU, ENC28J60 chip, and tuxgraphics library. Everything is working fine within the LAN, but if I tried to access it from outside the LAN (Internet), even with port forwarding or DMZ properly configured, I can't access the MCU-based...
Sorry for the very late reply, been busy with school and work.
For some reasons this function is not working for me:
void eeprom_set_passcode(char * pass)
{
eeprom_update_block((void *)pass,(void *)&e_passcode,sizeof(pass));
write_eeprom_byte(&e_passcode_check_byte,1);
}
But...
Thanks for the reply.
For now, I can live with the warnings :), my main concern is how can I assign the value of the eeprom_get_newpasscode() to a variable so I can use it for my authentication?
Is there anything I need to change on my function in order to do this:
passcode =...
Sorry to be a pain, but I ran into another problem. I can write to eeprom with the codes below without any problem but I am having a difficulty reading it and use for authentication:
#define read_eeprom_byte(address) eeprom_read_byte ((const uint8_t*)address) //any other way to do this other...
Finally, I managed to to rebuild my board.
It seems that reading and writing to EEPROM was not the problem but how I display it.
This code worked for me!
c = *progmem_s++
My question now is how can I check if eeprom is empty or not.
I need to check if e_passcode[10] is empty or not. If it is...
Yes that's it. Sorry I am not aware that it is tuxgraphics only library, I thought it is part of the AVRlib.
I am using the codes from tuxgraphics for the webserver with enc28j60. Also, I am using crosspack for mac and xcode.
Other than the missing bracket, is there something wrong on what I'm...
Interesting...
I just can't figure out what seems to be the problem. Using the code above, when I displayed mypass on the webpage, if I'm not getting garbage characters, I am getting different values from my html code...
I am quite new with C language programming especially with...
Hi Everyone,
I am new to microcontrollers and by following some online tutorials I was able to make an embedded webserver using ATmega328-pu and ENC28J60 chips. The webserver is working fine with a basic passcode authentication.
My problem now is I want the user to be able to change the...
I now have most of the concepts needed.
I will be creating a breadboard web arduino using ATMEGA chip + ENC. Then I will create a webserver using the available libraries. But I have one concern. I don't want the web application to be open to the public. How can I do authentication with the...
Thanks for the reply.
Does this mean that I don't need to purchase the Google ADK or the Arduino ADK and I can just use my breadboard arduino with the enc28j60. This is important for me as it is hard to get those ADK from my area as I can only get them online so I have to pay for shipment and...
Hi,
For my project study, I am thinking of creating a system that could power on/off a device through the use of Arduino and an android smartphone using TCP/IP connection. Then if I managed to make this work, I will integrate SMS control as well.
So the android smartphone connects to a...
