JN5148 - PC connection

[north2012]

Hello,

I am working with JN5148 JenNet Home Sensor Demo and Eclipse software development kit.

Did anyone have experience with UART communication with PC?

Regards

I have used USB to serial cables such as FTDI products to connect development boards (including Jennic) to a PC

OK, thank you very much for your reply.

The problem is that I am not very familiar with JN5148 programming. Most of the my work was with AVR and C#, but now I am in situation that I need to collect data form JN5148 (Coordinator plus 3 sensor boards) and present it in Win application developed in C#. My idea is just to add interrupt driven UART routine for Coordinator and to put readings from all sensors in one packet which will be transmitted to the PC. Any help for this function (initialization)?

For ATmega32, for example, I will add something like this:

in main function

UCSRB |= (1 << RXCIE);
GICR = 0b10000000;
MCUCR = 0b00001000;
SREG_I_bit = 1;
//interrupts active

interrupt routine:

void pc_int() iv IVT_ADDR_USART__RXC ics ICS_OFF
{
char request;
request = UART1_Read();
if (request == '@') //indication that PC has sent request for data
  {
   request_pom = 0; //global variable used in main; 
  }
  else
  {
  request_pom = 1;
  }
}

never had much experience with Jennic devices (after evaluation tests we went with XBee devices) so cannot help with programming them

if your existing PC code is in C# you can use the SerialPort component to connect to a COM port to talk to the Jennic device

I do not have problem to set PC application, I have already done that many times with AVR microcontrollers, but now I con not figure how to add UART routine to JN5148...

also worth looking on the Jennic forum
