#3899 Shift Registar 4014Posted by Vojin on 14 October 2010 - 05:40 PM in General Discussion
Just learned that here http://www.doctronics.co.uk/4014.htm Are there any Netduino example projects with those? #3896 Shift Registar 4014Posted by Vojin on 14 October 2010 - 05:25 PM in General Discussion
I'm trying to use Shift Register to control 16x2 LCD (http://geekswithblog...id_crystal.aspx)
The problem is that I ordered CD4014BE which has completely different pins than 74HC595
Any idea which pins to use for what?
#5385 POV on Netduino MiniPosted by Vojin on 27 November 2010 - 05:40 AM in Project Showcase
Excellent!
One note: Code is using 10 pins for LEDs, your blog schema shows only 8 LEDs and on video only 7 are actually turning on
#4023 Netduino & LIRCPosted by Vojin on 20 October 2010 - 06:00 AM in General Discussion
I'm trying to build IR remote for my Sony DSLR A350.
Simple setup: I have a LIRC file for IR Remote begin remote name Minolta_RC3 bits 8 flags SPACE_ENC eps 25 aeps 100 header 3872 1708 one 527 436 zero 527 1331 ptrail 527 pre_data_bits 24 pre_data 0xD3AC7D gap 9052 toggle_bit 0 begin codes one_sec 0x000000000000007F two_sec 0x00000000000000FF end codes end remote The problem is that LIRC values are in microseconds and I cannot turn irLED on or off for less them 1 millisecond. For example, bit "1" is LED on for 527 microseconds and then LED off for 436 microseconds: irLED.Write(true); Thread.Sleep(0.527); irLED.Write(false); Thread.Sleep(0.436); This doesn't work because Thread.Sleep accepts [int] Any idea how to wait for x microseconds? Is there .NET Micro equivalent to Arduino's DelayMicroseconds (http://www.arduino.c...layMicroseconds) #4074 HD44780 1602 16x2 LCDPosted by Vojin on 21 October 2010 - 10:12 PM in General Discussion
Got it yesterday from eBay for $3.10CAN.
Spend an hour to wire it and it works like a charm Now, I'm just waiting for shift registers to start bit more advanced projects #4707 HD44780 1602 16x2 LCDPosted by Vojin on 09 November 2010 - 02:42 AM in General Discussion #4050 Camera Shutter Release TimerPosted by Vojin on 21 October 2010 - 02:41 AM in Project Showcase
Cable - from old mouse (it has 7 pins, so I cut 4 of them and it worked Camera is Sony Alpha 350 (DSLR-A350), but connector is same for all Sony Alpha and Minolta SLR Connector Info Connector is just with 3 pins:
So to take picture, you need to focus (Connect A to B ) and then fire shutter (Connect C to B ) #4044 Camera Shutter Release TimerPosted by Vojin on 20 October 2010 - 10:07 PM in Project Showcase
One more Extremely-Simple-Project
Design: On the breadboard: How it works: http://www.youtube.com/watch?v=YG4yLwIarb4 Code: using System; using System.Threading; using Microsoft.SPOT; using Microsoft.SPOT.Hardware; using SecretLabs.NETMF.Hardware; using SecretLabs.NETMF.Hardware.Netduino; namespace ShutterRelease { public class Program { static Boolean status = false; public static void Main() { // write your code here OutputPort focus = new OutputPort(Pins.GPIO_PIN_D8, false); OutputPort shutter = new OutputPort(Pins.GPIO_PIN_D10, false); InterruptPort button = new InterruptPort(Pins.ONBOARD_SW1, false, Port.ResistorMode.Disabled, Port.InterruptMode.InterruptEdgeHigh); button.OnInterrupt += new NativeEventHandler(button_OnInterrupt); while (true) { if (status) { focus.Write(true); shutter.Write(true); Thread.Sleep(10); focus.Write(false); shutter.Write(false); Thread.Sleep(5000); } } } static void button_OnInterrupt(uint data1, uint data2, DateTime time) { status = !status; } } } Attached Files

Well.. it was 15 minutes project #4708 Audio TriggerPosted by Vojin on 09 November 2010 - 02:48 AM in General Discussion
Trying to build audio trigger using LM386 Audio Amplifier...
I have this so far... and it's not working What am I doing wrong?
