hamster Posted April 23, 2015 Share Posted April 23, 2015 Hi! I've been playing with the low cost ESP8266 modules, that present a IP-over-WiFi as a serial device, and you use modem-like AT commands to control it. I've just put up a project that allows the FPGA to connect to my Wifi network, then send status message to a service that is listening on my Linux VM. It is all done using VHDL state machines (no software CPU), and could most probably be made a little more compact. Because the serial port is running at 9600 and the AT command based protocol overhead it is a pretty low bandwidth solution, but enough if you wanted to add some basic WiFi telemetry to a design. The ESP8266 module used was under $7 - http://www.seeedstudio.com/depot/WiFi-Serial-Transceiver-Module-w-ESP8266-p-1994.html You can find all the source on my Wiki at http://hamsterworks.co.nz/mediawiki/index.php/FPGA_ESP8266 FlyingBlindOnARocketCycle, LariSan and JColvin 3 Link to comment Share on other sites More sharing options...
