2024 Muallif: John Day | [email protected]. Oxirgi o'zgartirilgan: 2024-01-30 13:23

Dragonboard 410c va Linker Sprite Mezzanine ilovalari uchun zarur bo'lgan barcha ma'lumotlarni o'chirib qo'yish kerak.

1 -qadam: Oldindan talablar:

Oldindan talablar:

Plataforma desenvolvimento (maqsad):

• Dragonboard 410c;
• Linker Sprite Mezzanine;
• Linux Linaro debian 17.04.1;
• SPI -ni yuklash tasvirini yuklash;
• Biblioteca Libsoc.

2 -qadam: Como Funciona va Comunicação Analógica Entre Dragonboard 410c E Linker Sprite mezzanine

U Linker Sprite Mezzanine -dan foydalanib, ADC protokoli Dragonboard 410c -ni o'rnatish uchun mo'ljallangan, ADC -ni birlashtiradi.

U chipi ADC uskuna va MCP3004 va Dragonboard 410c protsessorlari SPI interfeysi orqali.

3 -qadam: Habilitando interfeysi SPI Na Dragonboard 410c

Dragonboard 410c uchun SPI -ni yuklash tasvirini yuklab oling, lekin yuklash tasvirini SPI -ni kompilyatsiya qiling.

Dragonboard 410c -da yuklash tasviri bormi?

Dragonboard 410c -da yuklash tasvirini yoki SPI -ni yuklash tasvirini yuklab oling.

4 -qadam: Biblioteca Libsoc

a biblioteca a biblioteca que a vabos uses for a desenvolver aplicacõeses analógicas na Dragonboard 410c com Linker Sprite Mezzanine.

Biblioteca libsoc são ga bog'liq bo'lganidek:

• qurilish uchun zarur
• avtokonf
• avtomobil ishlab chiqarish
• libtool-bin
• pkg-config
• python-dev

sudo apt-get install build-essential autoconf automake libtool-bin pkg-config python-dev

Pronto! Aytish kerakki, biblioteca libsoc -ning asosiy vazifalari.

5 -qadam: Libsoc Na Dragonboard 410c -ni o'rnating

Ma'lumotni biblioteca libsoc -ga yozib qo'ying:

wget -c https://github.com/jackmitch/libsoc/archive/0.8.2.zipunzip 0.8.2.zip cd libsoc-0.8.2 autoreconf -i./configure --enable-python = 2 --enable- board = dragonboard410c --with-board-configs bilan sudo o'rnatishni amalga oshiradi sudo ldconfig/usr/local/lib sudo reboot

6 -qadam: Masalan: toymasin reostat

Aloqa uchun Spray Mezzanine, ADC1 portiga, slaydni qaytarish moslamasi va boshqa vazifalarni bajarishni o'ylab ko'ring.
