1. Deskripsi desain

Desain ini dengan hati-hati membangun sistem tertanam yang komprehensif dengan mikrokontroler berkinerja tinggi STM32MP157A sebagai unit kontrol inti. Sistem ini secara cerdik mengintegrasikan berbagai modul periferal seperti buzzer, tampilan tabung digital, layar dot matriks, sensor suhu dan kelembapan, indikator LED, dan tombol untuk membentuk perangkat pintar hybrid dengan fungsi yang kaya dan pengoperasian yang mudah. Melalui komunikasi serial, pengguna dapat secara fleksibel mengganti mode kerja sistem dan dengan mudah menerapkan fungsi dasar seperti jam alarm, pemutaran kotak musik, serta pemantauan dan kontrol suhu dan kelembaban.

perangkat keras inti

  • Unit kendali utama: Menggunakan mikrokontroler STM32MP157A, dengan kemampuan pemrosesan yang kuat dan antarmuka periferal yang kaya, ini memberikan landasan perangkat keras yang kokoh untuk sistem.

platform perangkat lunak

  • alat pengembangan: Menggunakan STM32CUBEIDE, lingkungan pengembangan terintegrasi yang intuitif dan mudah digunakan, sangat meningkatkan efisiensi pemrograman dan debugging perangkat lunak, memastikan stabilitas dan keandalan perangkat lunak sistem.

Sorotan fungsi sistem

  1. Peralihan mode yang fleksibel: Melalui komunikasi serial, pengguna dapat dengan mudah beralih di antara tiga mode jam alarm, pemutaran kotak musik, serta pemantauan suhu dan kelembapan untuk memenuhi kebutuhan penggunaan dalam skenario yang berbeda.

  2. Tampilan informasi dinamis: Sebagai jendela tampilan informasi sistem, layar dot matriks dapat menampilkan karakter Cina yang sesuai sesuai dengan mode kerja saat ini (seperti "jam" mewakili mode jam alarm, "nada" mewakili mode kotak musik, dan "pass" dapat berupa dianggap sebagai logo yang disederhanakan untuk pemantauan suhu dan kelembapan), memberikan umpan balik operasional yang intuitif kepada pengguna.

  3. Pengalaman interaksi tombol: Desain sepenuhnya mempertimbangkan pengalaman interaktif pengguna. Operasi fungsional yang sesuai dapat dilakukan di setiap mode dengan menekan tombol, seperti penyesuaian kecepatan dan volume kotak musik, peralihan lagu, kontrol jeda/putar, serta penyesuaian waktu dan pengaturan. jam alarm, mematikan jam alarm, dll.

  4. Kontrol cerdas suhu dan kelembaban : Sistem ini memiliki sensor suhu dan kelembapan internal yang dapat memantau kondisi lingkungan secara real time dan menerima instruksi pengguna melalui port serial untuk menyesuaikan ambang batas atas dan bawah suhu dan kelembapan. Setelah parameter lingkungan melebihi rentang yang ditetapkan, lampu indikator LED akan menyala sebagai pengingat batas untuk membantu pengguna mengambil tindakan tepat waktu.

2. Informasi konfigurasi dasar

Kotak musik telah dibuat sebelumnya, sehingga konfigurasinya tidak berubah:Kotak musik STM32

        

3. Konfigurasi STM32CUBEIDE

1. Pengatur waktu--100ms

2. Konfigurasi PWM (buzzer--PB6)

3. Konfigurasi port serial

Perhatikan pinnya

4. Konfigurasi IIC (suhu dan kelembaban, tabung digital, layar dot matriks)

5. Konfigurasi GPIO (LED dan tombol)

6. Komisi Informasi Nasional (NIV)

4. Pemrograman

(1) Kode kotak musik

Kotak musik telah ditulis sebelumnya, jadi kami tidak akan mengulangi operasi sebelumnya di sini. Kami akan menambahkan port serial dan konversi mode.

7. Ringkasan

Desain ini adalah sistem multi-fungsi yang sangat terintegrasi berdasarkan mikrokontroler STM32MP157A. Ini mencapai interaksi dan fungsi yang kaya dengan mengintegrasikan beberapa modul seperti buzzer, tabung digital, layar dot matriks, sensor suhu dan kelembaban, lampu LED, dan tombol. Sistem ini menggunakan STM32CUBEIDE sebagai platform pengembangan, memberikan kinerja penuh dan fleksibilitas mikrokontroler STM32MP157A, menunjukkan potensi penerapannya yang luas dalam desain sistem tertanam.

Ringkasan desain:

  1. Desain modular: Desain ini mengadopsi ide desain modular. Modul fungsional yang berbeda (seperti jam alarm, kotak musik, pemantauan suhu dan kelembaban) dirancang secara independen dan diintegrasikan bersama. Hal ini tidak hanya meningkatkan kemudahan pemeliharaan dan skalabilitas sistem, tetapi juga membuat setiap modul lebih fleksibel. Implementasi fungsional lebih jelas.

  2. Peralihan mode yang fleksibel: Peralihan fleksibel antara mode yang berbeda (jam alarm, kotak musik, pemantauan suhu dan kelembaban) diwujudkan melalui komunikasi serial, memungkinkan pengguna dengan mudah memilih fungsi yang diperlukan sesuai dengan kebutuhan mereka, meningkatkan kemudahan penggunaan dan kepraktisan sistem.

  3. Tampilan dan interaksi yang beragam : Layar dot matriks menampilkan karakter Cina yang berbeda (seperti "bel", "yin", "chuan") dalam mode berbeda, secara intuitif menunjukkan mode kerja saat ini dan meningkatkan pengalaman pengguna. Pada saat yang sama, kombinasi tombol dan kontrol port serial memungkinkan pengguna mengoperasikan sistem dengan berbagai cara, seperti menyesuaikan kecepatan dan volume pemutaran musik, mengganti lagu, menyesuaikan waktu alarm, mengatur beberapa alarm, dll., yang sangat berguna. memperkaya fungsionalitas sistem.

  4. Pemantauan dan penyesuaian suhu dan kelembaban: Sistem ini mengintegrasikan sensor suhu dan kelembapan, yang dapat memantau suhu dan kelembapan sekitar secara real time, dan menyesuaikan batas atas dan bawah suhu dan kelembapan melalui port serial Prompt diberikan melalui lampu LED, mewujudkan pemantauan cerdas dan penyesuaian lingkungan.

  5. Platform pengembangan yang efisien: Menggunakan STM32CUBEIDE sebagai platform pengembangan, menggunakan fungsi pengeditan kode, kompilasi, debugging yang kuat, serta fungsi perpustakaan yang kaya dan proyek sampel, ini sangat meningkatkan efisiensi pengembangan dan mengurangi kesulitan pengembangan.

  6. Demonstrasi kemampuan aplikasi yang komprehensif: Desain ini tidak hanya menunjukkan fungsi kuat mikrokontroler STM32MP157A dalam desain sistem tertanam, tetapi juga mencerminkan kemampuan aplikasi komprehensif perancang dalam pemilihan perangkat keras, desain sirkuit, pemrograman perangkat lunak, debugging sistem, dll.

Singkatnya, desain ini adalah sistem tertanam yang mengintegrasikan multi-fungsi, fleksibilitas, dan kemudahan pengguna, yang sepenuhnya menunjukkan prospek aplikasi luas dan potensi mikrokontroler STM32MP157A dalam desain sistem yang kompleks. Melalui penerapan desain ini, tidak hanya memperdalam pemahaman tentang desain sistem tertanam, tetapi juga meningkatkan kemampuan dalam memecahkan masalah praktis.
