Need help in programming

[Suria]

#define ACK_SUCCESS 0x00 //Module reply success
#define ACK_FAIL 0X01 //Module reply fail
#define ACK_NOUSER 0x05 //Module reply no user
#define ACK_USER_EXIST 0x07 //Module reply user exist
#define ACK_TIMEOUT 0x08 //Module reply timeout
#define ACK_ACCESS 0x03 //Module reply access allowed


what does this code mean? help school project due in 3 days~~

[Suria]

//configure reader setting
send_cmd(0x2E,0x00,0x10,0x00);//configure Time out(0x10 means timeout after approx. 7s)
delay(10);
receive_reply_nodisplay(); //get reply from UART but do not display
send_cmd(0x2d,0x00,1,0x00); //send command to configure not allowed repeat
delay(10);
receive_reply_nodisplay(); //get reply from UART but do not display

and this one tooo..

This program for what project?

Don't know to explain, there already have a comment at the program line. huhu.

CODE: SELECT_ALL_CODE

#define ACK_SUCCESS 0x00 //Module reply success
#define ACK_FAIL 0X01 //Module reply fail
#define ACK_NOUSER 0x05 //Module reply no user
#define ACK_USER_EXIST 0x07 //Module reply user exist
#define ACK_TIMEOUT 0x08 //Module reply timeout
#define ACK_ACCESS 0x03 //Module reply access allowed

CODE: SELECT_ALL_CODE

//configure reader setting
send_cmd(0x2E,0x00,0x10,0x00);//configure Time out(0x10 means timeout after approx. 7s)
delay(10);
receive_reply_nodisplay(); //get reply from UART but do not display
send_cmd(0x2d,0x00,1,0x00); //send command to configure not allowed repeat
delay(10);
receive_reply_nodisplay(); //get reply from UART but do not display

CODE: SELECT_ALL_CODE

#define ACK_SUCCESS 0x00


define is like we rename or declare something.

CODE: SELECT_ALL_CODE

send_cmd(0x2d,0x00,1,0x00);


This is function to send UART to the Fingerprint Reader. The protocol, you need to refer inside this function and open the manual.

I also have sample code Fingerprint Reader. It's only the function is different.
Cytron use:

CODE: SELECT_ALL_CODE

send_cmd(0x2D,0x00,0x01,0x00);


I use:

CODE: SELECT_ALL_CODE

uart_transmit(0xF5);
uart_transmit(0x2D);
uart_transmit(0x00);
uart_transmit(0x01);
uart_transmit(0x00);
uart_transmit(0x00);
uart_transmit(0x2D^0x00^0x01^0x00^0x00);
uart_transmit(0xF5);

thanks shahrul, it's okay. u're malay?

out of the topic question, if you become one of the assessor in our school, what would u ask regarding programming? i'm very nervous for the presentation.

Yes, I'm malay.
I'm google translate 'assessor', owh that.
If I'm assessor, I ask what microcontroller module you use, ex ADC, PWM, EEPROM, Interrupt, Timer, UART, SPI, I2C. Then asking what ever have in the source code..

[Suria]

PIC16F876A is an EEPROM right? ahhaha

don't worry, saya org melayu
