bạn ko hiểu gì về lập trình C hết nên đi chôm code bị thiếu file header.

[bjminhphung]

mình mới bước vào học vi điều khiển thôi nên chưa biết j nhiều mong bạn chỉ zúp với. cái filde header nó là cái j vậy bạn, bạn có thể chỉ mình với. mình lên mạng xin dc code về và viết lại bằng phần mềm keil c thì nó báo lỗi thế mà chẳng biết sao hết

[bjminhphung]

có ai giúp mình giải thích 1 số của đoạn code trên không giúp mình với
mins = hex_dec(recv_data(1));
hours = hex_dec(recv_data(2));
days = hex_dec(recv_data(3));
date = hex_dec(recv_data(4));
month = hex_dec(recv_data(5));
year = hex_dec(recv_data(6));
mấy cái hex_dec(recv_data) có ý nghĩa j zậy giúp mình với

[youaremylife]

Là hàm convert (chuyển đổi) kiểu dữ liệu
/*~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
**** Data Convert HEX-DEC and DEC-HEX ****
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~*/

bit_8 hex_dec(bit_8 hex)
{
return((hex/0x10)*0xA+(hex%0x10));
}
/*====================================*/
bit_8 dec_hex(bit_8 dec)
{
return((dec/0xA)*0x10+(dec%0xA));
}

cụ thể là chuyển từ số dạng hexa (hệ 16 0,1,2,.....,A,B,....,F) sang decimal ( hệ thập phân 0 - 9) và ngược lại
ví dụ số hex là 0x0A thì sang thập phân dec là 10 và ngược lại.
year = hex_dec(recv_data);
chuyển số dạng hexa recv_data sang định dạng dec và lưu vào biến year
