Thanks @William-Scott for your interest. really appreciate.
I bought Expansion Dock and thanks to serial connection I've realized that in the boot sequence there was Bad CRC error.
I've reflashed Omega by pressing reset button on power-up and choose correct option.
So now I'm back online.

Thank you @György-Farkas for detailed answer.
I've tried this ADC (on demo board) on Arduino and also received nothing.
I think that this board is broken.
I bought ADS1115 and now I can smoothly read from photodiode

If somebody will need that in future guys from Control Everything Community made working python example for Omega2.
(or at least it's working in my case with FW: 0.2.0 b191)

Hi All,

I've just bought PCF8591 to use some ADC. It connects via I2C but my Omega seems to doesn't like to work with it.
Here are console output of i2cdetect function. I've tried all 3 inputs. It always shows 0xff which means like 3v3 whether pin is grounded or not.

root@Omega-xxxx:/# i2cdetect -y 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- --
10: UU -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
30: 30 31 32 33 34 35 36 37 -- -- -- -- -- -- -- --
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
50: 50 51 52 53 54 55 56 57 58 59 5a 5b 5c 5d 5e 5f
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
root@Omega-xxxx:/# i2cset -y 0 0x48 0x02
root@Omega-xxxx:/# i2cget -y 0 0x48
0xff
root@Omega-xxxx:/# i2cset -y 0 0x48 0x01
root@Omega-xxxx:/# i2cget -y 0 0x48
0xff
root@Omega-xxxx:/# i2cset -y 0 0x48 0x03
root@Omega-xxxx:/# i2cget -y 0 0x48
0xff
root@Omega-xxxx:/# i2cset -y 0 0x48 0x01
root@Omega-xxxx:/# i2cget -y 0 0x48
0xff
root@Omega-xxxx:/# i2cset -y 0 0x48 0x02
root@Omega-xxxx:/# i2cget -y 0 0x48
0xff

I'm running on newest firmware release 0.2.0 b191
I thought that firmware upgrade will change something because I had same issue on v0.1.10-b160
The only difference is UU status at 0x10 address. I didn't have it on previous release, this address was empty.

My PCF8591 is powered up from 5v and I've check cables. they are ok.
According to my knowledge address 0x48 is also ok. Please see documentation

Could you please suggest how can I get proper readings from this ADC via I2C?

@William-Scott said in Omega 2+ bricked:

ssible avoid soldering until you need something "permanently" connected. The double quotes to indicate sentiment, not literal behavior. Do what you need to do. Think forward.
Do you have other docks (e.g. Expansion) that may be usable in troubleshooting?
take care!

Thanks for reply! I will try this later.
I cannot find any AP related to Omega. that's why I've tried to connect via UART. Actually I don't have any other docs but i've ordered one.

Hello,

After a long break I've tried to launch my Omega 2+ with Power Dock 2. It was working, and configured.
I've noticed that I have no Wi-FI from Omega and only solid amber LED from the begging.
I've tried to connect to console via FTDI cable with specs found here but console is blank.
So I've ensured that RX from FTDI is linked to Power Dock TX1, and accordingly TX to RX1
For sure I'm choosing correct COM port because while cable RX and TX wired together I've got chars on console output.

I've tried to Factory Reset but after 10s (or even more) of holding Reset Button nothing happened.
Same thing is when I hold Reset Button while powering up. Amber Diode flashing until i hold Reset Button, than once button is released become solid I should have bootloader menu but nope. Black console.

Direct connection of FW RST pin to 3V3 for approx. 10s to reset device also gave no results.

Do you guys have any idea what should I do to re-flash device?

EDIT:

I've found that console output are on RX0 TX0. so I solder wires to those pins. but blank console
