Dspic 30f4011

[tuongdtd]

Chào các bác trong diễn đàn!
em mới tim hiểu về dspic30F4011, ban đầu em tập viết lại các tut của anh Nam và biên dich thử, sau đó thử thay đổi code theo ý mình, em đang làm với vd3-1 về LCD của anh Nam nhưng đang bị lỗi mong được giúp đỡ.
khi biên dich thì báo lỗi như sau:

mong giúp đỡ!

bạn nên khai báo hằng vào cuối vùng nhớ (địa chỉ 0x7000 chẳng hạn )để tránh trùng với vùng nhớ dành cho chương trình
ví dụ :

const unsigned char __attribute__ ((space(psv), address (0x7000)))
//Chuoi ky tu se xuat ra LCD
Chuoi1[]="Hello world!\0"; //Chuoi ky tu se duoc xuat ra LCD
