MIKROE-1985 USB I2C Danna

Bayanin samfur

Kebul na I2C danna allo ne wanda ke ɗauke da MCP2221 kebul-zuwa-UART/I2C mai sauya yarjejeniya. Yana ba da damar sadarwa tare da microcontroller manufa ta hanyar mikroBUS™ UART (RX, TX) ko I2C (SCL, SDA). Hakanan hukumar ta ƙunshi ƙarin GPIO (GP0-GP3) da fitilun I2C (SCL, SDA) tare da haɗin VCC da GND. Yana goyan bayan matakan dabaru na 3.3V da 5V. Guntu a kan jirgin yana goyan bayan USB mai cikakken sauri (12 Mb/s), I2C tare da ƙimar agogo har zuwa 400 kHz, da ƙimar UART baud tsakanin 300 da 115200. Yana da buffer 128-byte don kayan aikin USB kuma yana tallafawa har zuwa 65,535-byte tsayin Karatu/Rubutun tubalan don dubawar I2C. Hukumar ta dace da kayan aikin sanyi na Microchip da direbobi don Linux, Mac, Windows, da Android.
