thanh ghi điều khiển Input/output PORT của 12F675 là TRISIO. Ko biết set_tris_a(); có tác động đến thanh ghi này hay ko??!! Tương tự cho lệnh output_a();
==> Bạn xem lại nhé  |
Uk` mình xem trong dataship thì đúng là điều khiển I/O PORT của 12f675 là trisio nhưng trong file "12f675.h" thì không thấy khai báo gì cả về trisio mà chỉ có Pin_Ax thôi
Đây là file trong CCS
