I have now tried installing update Version: 4.1.0 Update 6 (version 4.1.0.6) on two minis each time via TTL using the TTL version on each occasion MFDeploy seemed to complete ok however I now cannot access ping deploy or even re-flash either. If i ping the board I get Error no response from device. I have tried to re-flash (Via RS232) but each I try to connect to samba I get no board detected. If I manually set the 7x512 board type as detailed on the chip I receive a No processor valid ID fatal error. I have repeated this process with both v2.9 and v2.10 but to no avail. I’m not happy at the moment. I have 1 more mini but am scared to update however I need the serial fix to verify a few things I have been working on. I had come across a posing with the same error for another board which detailed the issue to be a security bit - any chance this is a similar issue? Any Ideas?

Hi, Chris has suggested that I post this here so here goes:

The following details simple 2 way Communication with a Windows Forms App - Rudimentary packet handling has been implemented via inclusion of an additional byte to the beginning of the packet which details the length of the string to be sent to the Netduino.

Once received the device filters the incoming data and recreates the string. A simple switch statement is then used to trigger functionality.

To see it in action, check out the video here:

I have attached the source to this post, hope its of help to someone, cheers, dyadica

Hi, I have wired up a sparkfun Triple Axis Accelerometer Breakout ADXL335 to the netduino as follows: x - PIN_A0 y - PIN_A1 z - PIN_A2 VCC - 3V3 && Aref GND - Gnd All works ok when I only try to read a single port, however if I try to read all 3 as detailed below the netduino drops out during the while statement and then I have to do a manual erase of the program via MFDeploy before I can successfully deploy to the device again. My program is as follows: using System; using System.Threading; using Microsoft.SPOT; using Microsoft.SPOT.Hardware; using SecretLabs.NETMF.Hardware; using SecretLabs.NETMF.Hardware.Netduino; namespace accelerometer { public class Program { // Define our accelerometer inputs static AnalogInput accX; static AnalogInput accY; static AnalogInput accZ; public static void Main() { // Create the Inputs accX = new AnalogInput(Pins.GPIO_PIN_A0); accY = new AnalogInput(Pins.GPIO_PIN_A1); accZ = new AnalogInput(Pins.GPIO_PIN_A2); // Output the values ??? while (true) { // When alone works fine Debug.Print("accX: " + accX.Read().ToString()); // This (multiple) doesn't // Debug.Print("accX: " + accX.Read().ToString()); // Debug.Print("accY: " + accY.Read().ToString()); // Debug.Print("accZ: " + accZ.Read().ToString()); } } } } I have tested the accelerometer via just running the single input code and swapping in the respective wire for x,y,z. The likelihood is that I am missing something obvious due to inexperience etc so with that in mind a few questions: I have assumed that I can wire in multiple analog inputs which can be read concurrently. Is this correct? Drawing upon peoples vaster pools of knowledge do I seem to have I wired up the system correctly? Does the Aref only cater for a single input? Cheers dyadica

Hi All Just go my netduino today from skpang.co.uk however without the small (no un-boxing for me) box despite that I instantly implemented the blinking led example and jobs a good un However I have a few questions whose answers seem to get more confusing as I read the forums. Primarily I am interested in communicating with a few windows forms applications. It seems that in order to achieve this I will have to update the firmware and deploy via serial. Is this defiantly the case, or is it possible to deploy an app to the device and then use the usb link for communication? All I want to do is turn on and off a couple of pager motors and led’s to begin with, via a windows form button press. If I do have to install the update patch would I follow the method as indicated in the following posting: http://forums.netdui...rased-netduino/ supplementing the serial patch etc Currently I own a TTL-232R Usb to TTL Serial Cable (5.0V) is this suitable for using with the netduino or will I need to obtain a 3V3 one? Can I persuade someone out there to produce a windows forms – netduino tutorial, I (and by the looks of it a few others) would be forever grateful Please excuse my ignorance on the subject, for I am new to all this etc, cheers
