Hello,

for a project I need to communicate with multidrop bus, a 9 bit UART communication. (no parity, one stopbit)

I tried to use the SerialPort class, but the SerialPort.DataBits property is out of range. It goes upto 8 databits.

In the AT915AM7X512 processors datasheet, I read that it can handle 9 bit USART communications through address bit handling.

Is it posssible with .NETMF to access or point to an absolute address and read or change the register data or control bit's?

I saw that the USART0 is in the 0xFFFC 0000 - 0xFFFC 3FFF range, I'm using C#.

anybody knows?

thanks,

Olivier

Hi, I'm new to Netduino and C#

in my first project I have a casting problem.

this code :

byte checkSum = 0 ;byte[] dataFrame = new byte[5];checkSum = dataFrame[2] ^ dataFrame[3];

gives me this error : 

Cannot implicitly convert type 'int' into 'byte'. An explicit conversion exists (are you missing a cast?) 

but, this way, it works

byte checkSum = 0 ;byte[] dataFrame = new byte[5]; checkSum  = dataFrame[2];checkSum ^= dataFrame[3];

does anybody know why the first code doesn't work.

I would prefer to use only one line of code instead of two for this operation, and like to understand what went wrong?

tx,

Olivier
