Pin assignments?

[tonton81]

Good evening sumotoy, I'm testing the gpioDigitalRead on the MCP23S17 and getting the pins (not in order) and number squared..

i cant seem to figure it out, and im actually worried if i should attempt the digitalwrite commands hehe
thanks

it doesnt go from 0 to 15 when i digital read, it's more like this when reading:
digitalread pin 0 reads pin 8
digitalread pin 1 reads pin 9
digitalread pin 2 reads pin 10
digitalread pin 3 reads pin 11
digitalread pin 4 reads pin 12
digitalread pin 5 reads pin 13
digitalread pin 6 reads pin 14
digitalread pin 7 reads pin 15
digitalread pin 8 reads pin 0
digitalread pin 9 reads pin 1
digitalread pin 10 reads pin 2
digitalread pin 11 reads pin 3
digitalread pin 12 reads pin 4
digitalread pin 13 reads pin 5
digitalread pin 14 reads pin 6
digitalread pin 15 reads pin 7

and of course, the variable it reads.
does this have something mixed in the library with MSB/LSB?
Thanks
Tony

oh possibly i have found the key, however i am still novice at remedying it, but the mcp23s* libraries seem to be using BYTE as it doesnt exist on the current IDE's :(, could this be the issue>?
thanks

Seems a stupid error in MSB/LSB conversion, I will check monday.

I'm experiencing the same with the PCA9555-based Funduino I2C to GPIO module.

Was this ever fixed for the PCA9655? I have some issues which could be similar to this.
