【Ochiq manba】T5L asosidagi konsol mikrofonini aralashtirish uchun reverb va echo boshqaruvi

——DWIN dasturchilar forumidan

Biz bugun DWIN Developer Forum mukofotiga sazovor bo‘lgan ochiq manbali korpusni taqdim etishdan mamnunmiz: T5L chipi asosidagi konsol mikrofonini aralashtirish uchun reverb va echo boshqaruvi. Bizning muhandisimiz T5L ning UART 4 ​​orqali reverb ishlab chiqish platasi bilan o'zaro ishlash uchun 800x480 pikselli displeydan foydalanadi, bu esa yuqori ovoz effektlari uchun reverb, aks-sado, nam tovush, quruq tovush, akustik, pasayish va kechikish kabi muhim audio parametrlarini aniq sozlash imkonini beradi.

(1) Ekran uchun asosiy dastur quyidagicha:

void main(){

INIT_CPU();//Tizimni ishga tushirish

PORT_Init();//IO portini ishga tushirish

T0_Init();//Taymer 0 ni ishga tushirish

T2_Init();//2-taymerni ishga tushirish

my_UART4_Init(115200);

uart_init();//Serial portni ishga tushirish

ws2812_writ_byte(8);//LED chiroqni ishga tushirish

RetMicSet();

kechikish_ms(1000);
