I don't have neither a programmer, nor a debugger, can I change the web page?
Only visually. If you need to add new variables, you need to add them in HTTPPrint.h which is also part of the stack, then rebuild and upload to the new code to PIC-WEB.

I received the board and one quartz crystal seems rotated at 45 degrees. Did you send me a defective board?
The quartz rotated at 45 degrees is normal. We have two types of such crystals – one of them requires 4 pads, the other only 2 pads. That is why we have provided 4 pads to be able to fit both crystals. All boards Olimex manufactures pass automatized optical inspection after assembly and obvious misplacements like these are impossible to occur.

Can I use the PIC-WEB as a TCP-IP to RS232 bridge?
Yes, the default demo software we ship PIC-WEB with creates a TCP-IP-to-RS232 bridge at port 9761, i.e. if you have connected for instance a MOD-RFID125-BOX to it and you listen to the PIC-WEB IP port: 9761 you can read the RFID tag info remotely by Ethernet. If you have problems with the communication in one direction, consider that the web page demo might be the root of the problem, open the demo and comment out "WEBPAGE_DEMO_UART" in "HWP OLIMEX_PIC_WEB.h" to enable the two-way UART bridge.
