PIC-WEB with Microchip’s TCP-IP stack allow development of easy applications for the web. The best thing is that you don’t have to be PIC programmer nor to know C, you can make all your project in html, java script, ajax and you have all PIC resources as dynamic variables so you can toggle GPIOs and read ADC values etc in your html code.
As you can see from the picture below:
The same resources for UART are also implemented:
and this way you can interface MOD-LCD4.3 over the internet:
for instance this happens when you send Clear command to the LCD over the web:
so with the new firmware you can have access to all UEXT module resources: relays, sensors, LCDs etc.
