Hi to all ... i know c# and vb.net i've some problem in hardware site!!! Im new in netduino, i've only a question ( 4 now ) , but every serial component, like this camera ( http://bansky.net/bl...ro-framework-2/ ) i can add in netduino 's hardware direct in D0, D1 only and i inizialize with : static SerialPort port = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One); and later i work whit byte data i think .. Can i have up to one serial controller to connect ? Can use netduino mini as the same of netduino ... ? Yes i think .. tnx 1000

On the Netduino and Netduino Plus you can have up to 2 UART devices, UART 1 is on Digital Pins 0 & 1, UART 2 is on Digital Pins 2 & 3. The hardware page for the Netduino shows the pin assignments and is the same as the Netduino Plus. The Netduino Mini however only has 1 UART on pins 11 & 12. The hardware page for the mini has all of its pin assignments.

There are devices which will allow you to add more UARTs via an SPI interface, which will work with all of the Netduinos.

Hi,

the Wiki says netduino mini has one TTL and one R232, so in total two UARTs or not?

It has two UARTs...but you'll generally use one of them for deploy/debug. So there is one UART remaining for your code.

Thanks, now i've only to try when camera will arrive !!

Chris,

What if I wanted to download the code over USB, but have my Netduino app use the serial port to pass data back to the PC for data logging? It seems like I should be able to do this without a USB to Serial chip, by using the PC's COM port directly. True or false?

Thanks,

Jeff
