Hi blow,


I tried this, with the MiniJTAG and ST-Link, and works. I used the CooCox Toolkit.



In Topic: Upgrading from N+1 to N+2

Hi Chris,


I did test not only my project but on a simple breadboard with a PCF8574.

I cannot beleive, too, I changed a lot N1 and N2, but it was consistent.

Hi Chris,


I sent a repro for you in this thread:


But I dit not get any response. After that I test some newer firmwares,

but I got the very same results.

Again it works under Netduino 1 and Plus 1.


(I used Netduino 1 for my home heating control, 

it worked two years without any problem in 24/7.

So I am rather sure my software is good.

But I cannot use with Netduino Plus 2).

Some I2C chip works for me with N+2, but for example PCF8574 does not work.

I tried newer and newer firmware but exactly the same. So I gave up.

N1 and N+1 works well but those was too restricted for me,

so I changed to Raspberry PI, and it works well, too.

Just one problem (at least) with the [color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]PCF8574 code - the device address is 0x20 not 0x38.[/color]

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]([/color] page 4)

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]If you write and no device is there you should see the address sent out.[/color]

Yes, you are right.

But pay attention there is a device with 'A' postfix: PCF8574A, it has 0x38 base address:
