Re: Setting up DI Wifi Sensor --Problems
So I might have a few thoughts on this as I can talk just fine to the dWifi via NXT-G (blocks coming soon) and LabVIEW with the latest enhanced fw. I actually had to send everything byte by byte to get it to work. (see the LV code posted to my blog) Before that I got nothing back, exactly as you des...

Re: Communicating via RS485
The RS485 blocks on my site use a handshake to ensure the message is sent. They then try to resend. However, sometimes it does fail completely... I am not sure this is something to do in the FW, rather in the code layered on top. Maybe an RS485 library needs to be made for NXC with some of this mess...

Re: I decided to finally make a blog and a special surprise!
So I shouldnt say that most of my top secret stuff is done (there is a rather cool one in the works now), but the shuttle was a huge time sink. So I do have some more free time now. I started the blog to give people a look into what I do (both at work and for fun). The really nice thing is that I ca...

Re: I decided to finally make a blog and a special surprise!
I just uploaded a new RS485 block with the new 2.0 VIs. Adding numeric support and boolean support tomorrow.
Also note, in testing these VIs, I learned the screen has a refresh rate of about 50 ms. You might need a wait to display some of the stuff at higher speeds.

Re: I decided to finally make a blog and a special surprise!
I have also posted some sample NXT-G code up there to go with the surprise blocks. I have some more blocks to post tonight. It is going to be a very active week on that blog!

I decided to finally make a blog and a special surprise!

The blog is at http://08milluz.wordpress.com I will be hosting all my public files from this site. Now for the surprise. If you wonder over to the blog and look at the files secti...

Re: Need some help on creating a RS485 library on NXC
Okay, I think I am off by 1 when updating the inbuffoutptr. Let me try that tonight and see.

Re: Need some help on creating a RS485 library on NXC
So John, I presume you look at the inbuffinptr and the inbuffoutptr on the receiver and looking the the outbuffoutptr and outbuffinptr to confirm it actually sent? Do those registers actually retrun the correct values as it is sent? That is how I wait for sending in the block and it appears to still...

Re: Need some help on creating a RS485 library on NXC
The receiver issue is likely part of it. I will dig through that tonight. I havent tried the NXT against my logic analyzer in a few weeks now, but I will give it another look to see if it is a sender issue. One potential issue that could arise would be async variable length messages, though this doe...
