#57959 Use netduino without NETMF

Posted by korbai on 05 May 2014 - 07:37 PM in Netduino Plus 2 (and Netduino Plus 1)

Hi blow,

 

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

#55986 Upgrading from N+1 to N+2

Posted by korbai on 10 February 2014 - 07:23 AM in Netduino Plus 2 (and Netduino Plus 1)

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.

 

Regards,

Zoltan




#55975 Upgrading from N+1 to N+2

Posted by korbai on 09 February 2014 - 06:00 PM in Netduino Plus 2 (and Netduino Plus 1)

Hi Chris,

 

I sent a repro for you in this thread:

http://forums.netdui...ge-3#entry42435

 

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).

 

Regards,

Zoltan




#55956 Upgrading from N+1 to N+2

Posted by korbai on 09 February 2014 - 09:00 AM in Netduino Plus 2 (and Netduino Plus 1)

Hello,

 

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.

 

Regards,

Zoltan




#54657 Intro to Netduino I2C?

Posted by korbai on 13 December 2013 - 06:37 AM in Netduino Plus 2 (and Netduino Plus 1)

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]http://www.ti.com/li...ink/pcf8574.pdf 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:
