Hi,
Today I checked the address range for the I2C device.
Beside the documented range from 0x50 upto 0x54,
I notice that:
-> 0x01 upto 0x07
-> 0x78 upto 0x7F
do not work either in my situation and do nopt generate a RoboPro warning.
I am using a simple Microchip I2C analyze tool.

These ranges are reserved.

See the latest I2C bus specificatie from NXP:

and also

for the set of reserved address in the 7 bits address space.Maybe this links could be added to the RoboPro I2C help file?
