MCP23017 with ESP8266 D1 mini

[duku602]

I am trying to use MCP 23017 expansion board, the I2C is working, I can access the A channel as input but B channel is not working.

Again, not matter what I do, the output (channel B in my case) will not work, I even tried the same code (and lots of variations including inverted logic) with ANOTHER mcp dip and same results.

PLEASE, someone to make a instructable on how to proper use expansion boards with HAA ! ! ! (it will be a lot easier to use them with sonoffs instead of esp32 + 220v to 5v module or LDOs.

Detailed steps to reproduce it vdd 3.3V A0 + A1 + A2 TO GND, address 0x20 [MCP23017] reset pin 18 to vdd 3.3v with 4.7K or without resistor

[MCP23017] SCL to D1 (gpio5) [MCP23017] SDA to D2 (gpio4) [MCP23017] GPB 7 (pin8) [haa pin 115] as output to relay (trigger active high) --- THIs channel is not working [MCP23017] GPA 0 (pin21) [haa pin 100] as input from touch module - is working properly

PLEASE HELP!!! I've spent days already searching on internet for someone that used HAA with MCP 23017.

Thank you !

Try removing this part, because it is not needed since output is declared at MCP array, and I don't know if it can create issues: [[108, 115], 2]

[duku602]

Hello, I've just removed the io part you mentioned ([[108, 115], 2]), and even whole "io" array entirely and still can't make it work. I also tested on another pins on channel B (output) and same result -> won't change state/voltage/anything.

Let me know if I can do anything else like flash a specific version or anything else as I really need the D1 mini to work with mcp23017.

Thank you!

[RavenSystem]

There is a bug with channel B outputs. It will be fixed in next HAA version. With current version, channel A works fine for outputs, then you can use it, and channel B for inputs.

[duku602]

Hello again and thank you for the quick response.

I did tried (before opening the issue) to use Channel B as input and channel A as output but, again, channel B [input in that case] was not reliable, it was self triggering randomly. Channel A worked like a charm as both INPUT or OUTPUTS; Channel B was failing as both input or output.

again, thank you for everything!

[RavenSystem]

Use this script, with channel A as output and channel B as input. Connect your button to GND and Pin.
