I2C send vs write

[slashinfty]

This package for interacting with I2C has both sendByte and writeByte, while the Kaluma I2C API only has write. What is the fundamental difference? If I was trying to mimic a library that used sendByte, how would I do that in Kaluma?

Additionally, "command code" is a parameter in the two functions of the i2c-bus package, which it is not a parameter in the Kaluma I2C API. Does this matter at all?

Thanks!

Hi @slashinfty
Kaluma i2c.write() function is the same as sendByte function and Kaluma i2c.memWrite() function is similar as writeByte function.
When you want to use i2c.memWrite() function as a 'writeByte', you need to set memAddressSize to 8 (Default) and use memAddress for the command of the writeByte. One difference is 'i2c.memWrite() is synchronous but writeByte is asynchronous function.

e.g) writeByte(SLAVE_ADDR, command, onebytedata) --> i2c.memWrite(onebytedata, SLAVE_ADDR, command)

Thanks! This helped me finish writing a package for Kaluma.
