Hello Everyone,

I'm building a network of controllers for big building and I want to use 4 SBC66EC boards to exchange information over Ethernet. I'm doing this because there are already Ethernet cables running all across the building back to a router.

I have each board reading a cluster of sensors and controlling a cluster of actuators. This is quite straight forward.

Now I want to control all 4 boards through 1 board. The master board will send my inputs and a few sensor data to the other 3 boards and they will send the sensor readings and status of the actuators back to the master to display on a webpage.

I tried to implement this by getting the boards to send webserver HTTP commands with Java script then I realised they will not communicate if the webpages are not open.  :oops:

Can someone please guide me in the right direction to set up the communication using Ethernet? What protocol shall I use and how do I get started?

Thanks!  :mrgreen:

SBC66EC & SBC66ECL / Download Flash Data via Webpage

I have reserved a few blocks of the SPI Flash for data logging and I am wondering if I can download the data as a .txt file through the webpages. Any suggestions on where to start?


SBC66EC & SBC66ECL / Data logging SPI Flash
« on: February 23, 2014, 04:39:47 PM »
I want to log some sensor data on the PIC and I am thinking of using the SPI flash because the library is already there (nz_xFlash.h, spiFlashWinBound.c).
I am aware that the webserve is hosted on the SPI flash and I don't want to accidentally corrupt it and other programs, is it possible to reserve a 20 KB block of memory maybe at the end of the memory address, and what would you recommend for the address range of that block?
