Danny,

Do you have a volt meter or multimeter?

If so, you should measure the voltage present on your motherboard's pins. Most serial interfaces use 12 volts which is too much for a Netduino. Please be careful.

thank you both for your replies. i, too, believe that i will really enjoy using this thing once i get over this first bump.

i have considered buying another device for interfacing, but i seem to be predisposed to doing things the hard way.

on my motherboard there is a 'COM1' rectangular 10 pin (minus one) socket. 5 pins on top, 4 on bottom. like this:

i experimented today with pins D0 and D1 on the shield base connected to (what i think are) pins 2 and 3 of this socket. i got some lights and strange characters to come up on the program http://realterm.sourceforge.net/

but i do not know what the pinout is, nor which pins need to be connected, nor how to confirm the connectivity.


once all of that is done, i am confident i can trudge through the rest on my own.


your help is appreciated.

Hi dannykyle,

First off, welcome to the Netduino community. Once you get over your initial frustrations I believe you will have lots of fun learning with your Netduino.

If you find that your computer does not have a serial port connector, don't dispair. Their are other options.

In particular there are USB to serial converters that plug into a USB port on your computer. One thing to be careful of though is the voltage. "standard" serial uses 12 volts which is too high for a Netduino.

This cable might work for you as it uses Netduino compatible voltages: https://www.adafruit.com/products/70

Alternatively this might be even better: FTDI friend There is even a full tutorial on how to use it.

Hello Avax,

Welcome to the Netduino forums.

In the past there has been some discussion of CANbus, but I don't know what the current state of that interface is for Netduino.

I do know there are several people (including myself) who would like to see it on the Netduino.

Hopefully others may provide more detailed information.

Hi everyone,

I am a total newbie here.

I have a project I am working on involving LIDAR. The laser measurement device supports CAN bus and I would like to communicate with it using CAN.

I like the netduino platform because I am an experienced .net developer and would like to stay in visual studio if possible.

Anyway I did a search here on "CAN" and nothing came up, but it very likely could be a filtered word like "the".

If anyone has any information on an existing project or thoughts on what hardware would be required to communicate on a CAN bus it would be appreciated.

Regards
Avax

I have been looking at Go module development and can see that another tool in people's toolset is a logic analyser would you say that this is he case?

With this in mind I was thinking of getting the sparkfun bus pirate as it's quite cheap. Would you say that this is a worthwhile purchase?

Have you checked out http://dangerousprot...-pirate-manual/ ?

Keven is correct that a logic analyzer is a great tool, and will do more. That being said, the stuff from dangerous prototypes can't be beat for the money. $30 for the bus pirate is very cheap; of course you will probably want to buy some cables etc which will bring the price up some.

You may also like their logic sniffer - http://www.seeedstud...2.html?cPath=75 At $50 it too is very attractively priced.

Status update: the basic flashing routine for STM8S modules is working, at this moment in byte mode (*). Now, when the reflashing app for STM32 is available, it can be extended to include flashing of STM8S-based modules, so we can have an unified interface.

(*) Byte mode is the slowest, word and block programming are faster, but a little bit more complex.

Would you be willing to give a status update as well as information on how to get a copy of the flashing routine?

Thanks.
