——Dari Forum Pengembang DWIN
Dalam edisi ini, kami mendorong kasus sumber terbuka pemenang penghargaan dari DWIN Developer Forum - Multi-function Weigher. Insinyur ini mengadopsi layar pintar COF 4 inci, dan melalui interaksi data antara inti T5L OS dan modul HX711 serta set sensor tekanan 5kg, pengguna dapat dengan mudah menyadari fungsi tampilan penghitungan seperti berat, harga satuan, harga total, tara, dll. ., serta fungsi penghitungan, pelacakan kurva perubahan berat, dan koreksi keakuratan penimbangan, dll., sehingga mudah untuk beralih di antara skenario aplikasi yang berbeda untuk menikmati pengalaman penimbangan yang nyaman dan efisien.
1. Pengembangan UI
2. Desain C51
Bagian dari kode referensi timbangan untuk mengimplementasikan fungsi penetapan harga adalah sebagai berikut:
// Halaman Harga====
#tentukan VALUATION_UNIT_PRICE_ADDR 0x1010
#tentukan VALUATION_GRAM_ADDR 0x1000
#tentukan VALUATION_TOTAL_PRICES_ADDR 0x1020
uint32_t valuation_decorticate = 0; // Harga Tara Berat
uint32_t penilaian_unit_harga = 0; //Harga satuan
// Penyegaran Harga Satuan
