Hai!

Could anybody help me?!

16F88 yang hanya memiliki I2C Slave hardware, Anda harus memilih sebuah PIC dengan MSSP modul.Anda akan mempunyai untuk menulis sedikit tertutup I2C rutin.
Juga silakan gunakan kode tag ketika posting kode.

Hai,

1.The 'Utama' fungsi yang tidak ditentukan.

2.Sht dengan perintah kode ini tidak diberikan.

3.Dalam COMWAIT fungsi, TRISA1 tidak set ke 1.

Salam,
Laktronics
