Front and back view of I2C 1-Wire Click Board designed in mikroBUS form factor.View full image
I2C 1-Wire click carries DS2482, a “bridge device” that performs bidirectional conversions between I2C masters and 1-Wire slave devices. These can be EEPROM chips, temperature sensors and similar devices that have momentary high source current modes. I2C 1-Wire click enables any host with I2C to generate properly timed 1-Wire waveforms to its slave devices.
The I2C interface (mikroBUS SCL and SDA pins) supports both standard I2C (100kHz max) and fast (400kHz) communication speeds. In addition to the mikroBUS socket, I2C 1-Wire click has an 8-channel pinout (each pin an independently operated 1-Wire I/O).
The board is designed to use either a 3.3V or 5V power supply.
Examples are written for :
- EasyMx PRO v7 for STM32 - STM32F107VC
