#16400 Netduino Firmware v4.2.0 BETA 1

Posted by Edward on 06 August 2011 - 08:53 PM in Beta Firmware and Drivers

No problem, I'll do that, already have the debugger installed. By the way, yes I too have had the crashes where there is no bluescreen just straight to BIOS.

#17575 Netduino Plus Firmware v4.2.0 RC1

I bumped into this too. The regex library is a port of an old (but worthy) Apache Java library (Jakarta)to C# (it's not native). It doesn't support quite the same syntax as the desktop .Net regex library (which is a little irritating). One thing that's not implemented is named capture groups af far as I'm aware. There are also some differences on what characters have to be escaped. I ended up downloading the library source and compiling it to find this out. Maybe these inconsistencies are worthy of a 'bug' on CodePlex. For me the performance from a non-native library and its cosiderable memory footprint made me look for simpler techniques for what I was trying to achieve.

No. We're awaiting a revised build from Secret Labs. See http://netmf.codeple...m/workitem/1166

Today it says "need more input". I hope tomorrow it says "need more RAM" ;->

#16916 So how does the SD card stuff work anyway?

Posted by Edward on 21 August 2011 - 01:50 PM in Netduino 2 (and Netduino 1)

On the Netduino Plus the SD card sits on the SPI0 bus and the SPI1 bus is available to the user. But you say you are not using the Plus so what SD card solution are you using and on which interface? How have you got the chip select lines for the SD card and the VS1053 connected?

Can you post a link to some info on the VB1053 please. I tried googling it but didn't find any relevant results.

#16746 Update:UDP Broadcast Send/Receive fixed for next release

High five!

#16739 Update:UDP Broadcast Send/Receive fixed for next release

I've reproduced this too while porting the framework for xAP home automation to the N+. So lookes like the define set to 1 enables a filter that stops broadcasts. FYI broadcast tx and rx do work on the address 255.255.255.255 but not the local subnet broadcast eg 192.168.1.255. No xAP without broadcast. Vote added. What I'm not clear on is if this is an issue for the MF team or Secret Labs. Not quite worked out where that division of responsibility falls.

Correct me if I'm being 'blind' but it seems strange to me that there's no links to info on the Plus or the Mini from the netduino.com homepage.

#25955 What's going on with the >= operator?

Posted by Edward on 25 March 2012 - 06:04 AM in Netduino Plus 2 (and Netduino Plus 1)

Where I struggled was with the base. I needed to use the Natural Logarithm base of 2.718281828 to get the right result, so:
Log(tempBead.Read(), 2.718281828);

That base constant 'e' is in the math library as System.Math.E
