#50492 Another Newbie Steps into the Arena

Posted by hanzibal on 14 June 2013 - 08:51 PM in General Discussion

Halogen light contains lots of IR so, like Paul said, watch out if the room is heavily lit and with what. I made something similar with a electrical model car race track where I could use photointerrupters since those cars have small "fins" sticking down a slot in the middle of each track. I suppose you need to time each car separately and not just the winner which makes it more difficult. Another idea might be to use micro switches buried in each track at the finish line. The switches would have to be fitted with with fairly long arms to make them easy enough for cars to lever as the they rush by barely touching the switches. This might be the easiest way to do it.

Where have you been during your time in exile?

#50764 issues moving from 4.1 to 4.2

I see. Usually when I accidentally run the emulator, I get an exception since it does not have the periphals I'm working with :-)

The emulator showing up would indicate that you haven't actively set the deployment channel to USB (or COM port for the mini) but I would think you've already checked that?

Sometimes VS looses the setting and I'll have to goto project properties and put it back.

Are you sure the name even sticks to the board?

#56338 Hitachi HD44780 LCD controller

Yes, 8 bit mode would be faster - in 4 bit mode, you have to transfer the low and high nibble of each byte separately while as in 8 bit mode, you transfer a whole byte in each transaction. Will you be using a separate device (shift reg or similar) in between the Netduino the LCD and if so, may I ask which?

#50548 file on SD card from Ethernet

Hi michel!

What is your setup?

Do you have a Netduino Plus attached to your network where the SD card you wish to modifiy is inserted into the CD card slot of the Netduino?

What kind of device needs to modify the SD card, is a PC, another Netduino or some other kind of network attached device?

#50658 start a new line in a TXT file

I usually use newline 'n' only and not vertical tab 'r' and as far as I remember, it should work.

Of course, when all else fails, you can always issue multiple calls to WriteLine().

#50584 looking for an old netduino 1 used ??

I got a Netduino Plus that can be flashed to behave the same as a regular Netduino (i.e. flash image w/o Networking) that I'm not really using if that works for you. I'm in Sweden which might render some additional shipping costs but I don't know how much.
