![]() Arduino/libraries/Wire directory on the machine you write your code on. In these cases, the piecewise API is helpful, even though it is less efficient for long transfers since it can’t operate asynchronously. The Wire Library is a series of files in plain text that exist in the. However, sometimes it can’t handle certain formats, such as in writeReg() where reg is outside the pBuf array. The transaction API is nice: you just pass it an address, a buffer, and a length, and it will handle sending or receiving the data. Int writeResult = i2c.write(_addr << 1 | 1) Īs you can see, there are basically two different I2C APIs: the “piecewise” one that uses start(), stop(), and the one-argument read() and write() functions and the “transaction” API that uses the multi-argument read() and write() functions. to indicate an i2c read, shift the 7 bit address up 1 bit and set bit 0 to a 1 ![]() Void DFRobot_BMX160::readReg(uint8_t reg, uint8_t *pBuf, uint16_t len) Kits are a great way to get started with Arduino. ![]() I2c.write(_addr << 1) // to indicate an i2c write, shift the 7 bit address up 1 bit and keep bit 0 as a 0 We offer a software tool, a community website and services in the spirit of Processing and Arduino, fostering a creative ecosystem that allows users to. Void DFRobot_BMX160::writeReg(uint8_t reg, uint8_t *pBuf, uint16_t len) This is my best guess at an equivalent: I2C i2c() Most of this translates 1:1 using the Mbed I2C class. cpp are the parts that let you write the easy-to-understand Arduino code, and twi.h/twi.c are the parts that take your easy-to-understand code and reconfigure.
