masalah dengan serial comm & PAL video out

H

Hasher

Guest
Saya bekerja dengan PIC18F2420 (8 Mhz & HS-PLL) & Hi-Tech PICC-18 compiler.

Aku sedang melakukan proyek untuk menerima karakter serial data & tampilan karakter-karakter di Sytem PAL TV.

Untuk melihat data karakter yang disimpan dalam ROM PIC sempurna aku o / p di TV.

Untuk komunikasi serial dengan PC saya punya bagus o / p pada hyper-terminal

NAMUN
ketika saya mencoba untuk menggabungkan dua bagian aku tak punya kesalahan tapi aku tak punya o / p di TV.

Apakah karena aku sedang memindahkan data pada port C dan pada saat yang sama Saya menggunakan TX & RC pada pin 6 & 7 di port C?

apa pendapatmu?

Catatan: beberapa kode tidak ada di sini.
