Всем привет. Недавно столкнулся с тем что нужно было управлять звуками, подключил модуль , а кода нет чтоб управлять. Начал искать для Микропаскаля для PIC . Нашёл только для С++ , пришлось переделать , делюсь кодом со всеми.
PASCAL
Пример использования.
DFplayer(track, 0x0101); // 01 — папка 01-трэк
delay_ms(100); // выдержка
DFplayer(volume,30); // установка звука
delay_ms(100);// выдержка
DFplayer( play ,0);// команда проигрывание
- PROCEDURE DFplayer (F: WORD; DAT : WORD );
- PROCEDURE write_comand ( VAR _CMD :array[10] of char);
{
// FF+06+03+00+00+01=0109
// 0-0109=FE F7
// Sample #2: In case of the play command it would be:
// 0 1 2 3 4 5 6 7 8 9
// 0X7E, 0xFF, 0x06, 0X0D, 00, 00, 00, 0xFE, X, 0XEF
// 0x06+0X0D+0xFE= 100010001 (binary) ---> negate 011101110 =0xEE
// So your checksum for byte 8 is 0xEE
// 7E FF 06 0F 00 01 01 xx xx EF
// 0 -> 7E is start code
// 1 -> FF is version
// 2 -> 06 is length
// 3 -> 0F is command
// 4 -> 00 is no receive
// 5~6 -> 01 01 is argument
// 7~8 -> checksum = 0 - ( FF+06+0F+00+01+01 )
// 9 -> EF is end code
}
