MIKROE-1985 USB I2C Pịa

Ozi ngwaahịa

Ọpịpị USB I2C bụ bọọdụ na-ebu MCP2221 USB-to-UART/I2C ntụgharị protocol. Ọ na-enye ohere nkwurịta okwu na microcontroller lekwasịrị anya site na mikroBUS™ UART (RX, TX) ma ọ bụ I2C (SCL, SDA). Bọdụ ahụ nwekwara ihe mgbakwunye GPIO (GP0-GP3) na I2C (SCL, SDA) yana njikọ VCC na GND. Ọ na-akwado ma 3.3V na 5V mgbagha ọkwa. Ihe mgbawa dị na bọọdụ ahụ na-akwado USB zuru oke (12 Mb / s), I2C na ọnụego elekere ruo 400 kHz, yana ọnụego UART baud n'etiti 300 na 115200. Ọ nwere ihe nchekwa 128-byte maka ntinye data USB ma na-akwado ruo Ogologo 65,535-byte na-agụ / na-ede ihe mgbochi maka interface I2C. Bọdụ ahụ dakọtara na akụrụngwa nhazi Microchip yana ndị ọkwọ ụgbọ ala maka Linux, Mac, Windows na gam akporo.
