PIC Lesson: Seven Segment
Bagaimana anda ingin menyalakan 7 Segment atau membuat kiraan nombor?
Langkah pertama anda perlu tahu cara sambungannya. Untuk di sambungkan kepada Microcontroller PIC, anda boleh memilih sama ada menggunakan 7 segment Common anode atau Common Cathode. Sambungannya seperti di bawah.
Anda perlu memberi signal yang betul untuk menunjukkan nombor di 7 segment. Berikut adalah jadual penukaran daripada nombor decimal kepada kod 7 segment.
| DECIMAL | 7 SEGMENT | |||||||||
| A3 | A2 | A1 | A0 | a | b | c | d | e | f | g |
| 0 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 |
| 0 | 0 | 0 | 1 | 0 | 1 | 1 | 0 | 0 | 0 | 0 |
| 0 | 0 | 1 | 0 | 1 | 1 | 0 | 1 | 1 | 0 | 1 |
| 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 | 0 | 1 |
| 0 | 1 | 0 | 0 | 0 | 1 | 1 | 0 | 0 | 1 | 1 |
| 0 | 1 | 0 | 1 | 1 | 0 | 1 | 1 | 0 | 1 | 1 |
| 0 | 1 | 1 | 0 | 1 | 0 | 1 | 1 | 1 | 1 | 1 |
| 0 | 1 | 1 | 1 | 1 | 1 | 1 | 0 | 0 | 0 | 0 |
| 0 | 0 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 1 |
| 1 | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 0 | 1 | 1 |

PS: of course I used the Hi-Tech C compiler in MPLAB. :-)
I created the hex file with MPLAB 8.86, but once simulated RealPic Simulator 1.3, are not displayed correctly number from 0 to 9.
Where did I go wrong?
Thank you.
This is my hex (seven_segments.hex):

Vito, you paste hex file, how can I understand that. Just follow software, compiler and PIC I use.
saya nak tanya, saya dah try burn program ni dalam pic, tapi….tak dapat
mcm mana nak tahu beza
__CONFIG(0x3F3A);
AND
_CONFIG ( 0x3F32 );
saya try wat 7 segment guna yg kedua tak dapat
uiks. ini ilmu baru nih..
