Hướng dẫn sử dụng CodeVisionAVR

Chào các bạn, để bắt đầu học vi điều khiển AVR chúng ta cần phải có một công cụ soạn thảo code mạnh điển hình như CodeVisionAVR cho phép soạn thảo code, dịch code hex, debug, nạp chip, hỗ trợ viết code sẵn..... và rất nhiều thư viện cho bạn sử dụng với code C. Hôm nay chúng ta sẽ làm quen với công cụ này, giúp các bạn thành thạo hơn khi sử dụng phần mềm cũng như các bạn mới học về AVR.

Để bắt đầu, máy tính của các bạn phải có một phiên bản CodeVisionAVR, các bạn có thể tải dễ dàng về trong phần Tài Liệu của SangTaoClub.Net, và tiến hành cài đặt, crack theo hướng dẫn.

Sau khi cài đặt hoàn tất, crack thành công bạn sẽ có ngay một công cụ soạn thảo cực mạnh cho AVR.

Ta bắt đầu chạy chương trình và làm quen với giao diện phần mềm:

B1. Khởi chạy phần mềm:

Hướng dẫn sử dụng CodeVisionAVR

B2. Tạo một project mới

Hướng dẫn sử dụng CodeVisionAVR

File > New

Hướng dẫn sử dụng CodeVisionAVR

Chọn Project > OK > Yes > OK

Hướng dẫn sử dụng CodeVisionAVR

Chọn chip và chọn tần số dao động cho chip

Ở đây các bạn có thể chọn bất kỳ thư viện code sẵn nào mà bạn muốn CAVR sẽ tự động tạo mã và chèn vào cho bạn. Như trên ta có thể sử dụng LCD (LCD16x2...), ADC, Timer, PWM, WDT, I2C (DS1307), 1wire (DS18B20), SPI, UART, Analog Comparator....

Cuối cùng ta tick vào biểu tượng hình bánh răng để lưu các file trong project lại, lưu tất cả chung vào một thư mục:

Các bạn cần phải đặt tên cho 3 file quan trọng khi tạo project: C, PRJ, CWP

B3. Dịch code sang file HEX, ta bấm vào biểu tượng Build trên thanh công cụ

Hướng dẫn sử dụng CodeVisionAVR

Trình biên dịch sẽ hiện ra một bảng thông báo, nếu code không vấn đề gì thì như sau:

Hướng dẫn sử dụng CodeVisionAVR

Nếu báo Errors thì sẽ ko tạo được file Hex, còn Warnings thì vẫn tạo file hex. Nếu có lỗi ta chỉ cần click đúp vào tên lỗi là nó tự trỏ tới dòng bị lỗi:

B4. Cài đặt lại một số thông số cho project như chân giao tiếp LCD, thạch anh.... ta làm như sau:

Tick vào biểu tượng hình cái cờ lê

Hiện ra hội thoại và các bạn chọn các Tab tương ứng để thay đổi:

OK! hôm nay chúng ta sẽ dừng lại ở đây, các bài viết sau chúng ta sẽ đi vào học AVR qua các ví dụ luôn :)

    Bạn nén project lại, kèm cả mô phỏng trên proteus 7.10 nhé, rồi up thành một bài viết thảo luận.

    Lấy 8bit thấp có 2 cách là ép kiểu (unsigned char)biến; hoặc biến chứa ở dạng unsigned char nó sẽ tự xén bit cho bạn, còn khai báo dữ liệu flash bạn sửa lại là flash unsigned char thay cho unsigned flash nhé..

    em quét ma trận, nhưng gặp vấn đề là khi ghép các mã led 8 bit thanh 16 bit (dùng để dịch lên xuống), nhưng khi lấy ra lại thì chỉ có 8 bit cao là đúng, còn 8 bit thấp thì chỉ có mã đầu tiên (_16_bit[0]&0x00ff) là đúng còn lại là sai hết. các mã led đã được kiểm tra lại trước khi ghép, ad cho em hỏi có phải do lỗi của IDE trong codevisionavr vì mã led trong bộ nhớ flash. mới lần đầu quét ma trận dùng avr,bộ nhớ flash của avr, mã bị thế này khó chịu thật, (em dùng bản 2.05) em thấy codevision còn có lỗi là vòng lặp for không cho đếm ngược tới giá trị 0(-- tới>=0), nó sẽ chãy mãi không dừng lại. thông tin này là để em chứng minh, ide có vấn dề, và không biết có phải do nó gây ra lỗi đầu tiên mà em đề cập đến không. code của em như thế này ạ:
