Tiny HTTP server controlling a DigitalOutput.
Turn LED1, or other digital output, on/off using a web browser.
In this example we create a HTTP server for the STM32F407VET6 black board that will serve a simple Web page to remotely turn LED1, or other digital output, on/off by using a web browser.

Notice that DHCP is turned on by default. The IP address assigned to the WebSwitch server along with an instruction how to use it is printed to the connected PC's serial terminal window during program start up.
To use static IP address uncomment and adjust line #221 in main.cpp.
A DP83848 module is used as Ethernet interface.
Wiring
| DP83848 module | STM32F407VET6 board | |||
|---|---|---|---|---|
| VCC | <=> | +3.3V | ||
| GND | <=> | GND | ||
| MDIO | <=> | PA_2 | ||
| MDC | <=> | PC_1 | ||
| OSCIN | <=> | PA_1 | ||
| CRS | <=> | PA_7 | ||
| RX0 | <=> | PC_4 | ||
| RX1 | <=> | PC_5 | ||
| TX_EN | <=> | PB_11 | ||
| TX0 | <=> | PB_12 | ||
| TX1 | <=> | PB_13 |
Notice that because the RX_ER line is not used the DP83848 module doesn't have to be modified.
The project was inspired by the Tuxgraphics Web Switch. Thank you Guido!
