Hello,
I need some help with a robo-tank pH board i just purchased. I have a brs probe. I built my own reef-pi that is running on reef-pi 5.1.
The board gets a continuous 5v. The jumper is on the 5v selection. I set it up following the steps in the reef-pi manual using the ph-EZO driver and the decimal address sent with the phBoard (98). (It also said the hex address is 0x62). i2c is enabled in raspi-config. This is the only i2c device connected. The green light is on on the board.
Reef-pi doesn't seem to recognize the device. I don't get any reading, nothing happens when I click calibrate.
This is the error in reef-pi:
"ph subsystem: Failed read probe:pHError:write /dev/i2c-1: remote I/O error"
i2cdetect returns:
pi@raspberrypi:~ $ sudo i2cdetect -y 1 0 1 2 3 4 5 6 7 8 9 a b c d e f
00: -- -- -- -- -- -- -- -- -- -- -- -- --
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
60: -- -- -- 63 -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --

Not sure I understand this exactly, but the sheet that came with the board said the hex address was 0x62, yet this returned 63?
If anyone has any suggestions I would appreciate any help.
Thank you,
Don't mind the errors prior to the last. I was messing with different i2c addresses in reef-pi. The last one is with everything entered as it should be.
