The command] A enables the I2C in Master mode.
The command takes two parameters. The first parameter is the I2C address of the Slave
device. The second parameter is the clock. In the standard mode I2C, the 7 most significant
bits represent the address and the LSB bit will be used as R/W bit. When issuing slave
address as first parameter, it is recommended to left shift the actual I2C slave address by
1 so that the last bit can be used for R/W bit.
The command] R reads data from the I2C slave
device. The command takes the length of the data to be read as the parameter. The current
firmware is designed to accept 2-digit value as parameter. A single-digit byte read will
result in an error. E.g. ]R,9 – The firmware expects the value as 09.
