With this example one can load an internet page from an HTTP server.
At this moment the remote IP address is fixed in the code and it loads the default file from the server.
All data received from the HTTP server is sent to Uart1 where it can be picked up by a uart program to display or to save to a file.

2023-05-10: Added correct TCP establish connection and TCP close connection. After a while the server closes its connection, so in the previous version communication with the server was lost after a while. This is solved now.

2023-05-06: Made the routine 'CheckToSend' work properly.
 

The project runs on a mini32 board (P32MX534F064H), but can easily be ported to another environment.

It uses the 'Uart_Receiver_P32' library (to capture uart input under interrupt, see https://libstock.mikroe.com/projects/view/102/uart-buffered), the MikroE 'Conversion' library, the 'Strings' library, the 'Uart' library and of course the 'Net_Wireless_MCW1001' library.

At the start of the program (after the connection to the accespoint is made and the TCP communication is established of course) a standard 'GET' request is sent to the HTTP server.

All data received from the HTTP server (so, the received webpage) is sent via the Uart1 output to a tool capable of showing that into. All data received via the Uart1 input (coming from e.g. a PC) is sent to the HTTP server.

The Uart1 is set at 115200 baud.

Keypad_I2c

10

Library for a 4x4 keypad connected to the PIC via an PCF8574 I2c expander (Two I2c lines in stead of 8 I/O pins). This saves a lot of PIC I/O pins. Permits also small PIC's (with low pin count) to control a keypad.
