Hello, Since i'm a beginner at embeeded electronics, i have to ask: Is there a way to connect multiple UART chips to RPi's GPIO pins so you can have multiple serial ports (once you write the Linux drivers)? Can any GPIO pin become a UART TX or RX or there is something special about the UART pins?

There is some code not represented here, there is another source file with a state machine in it, which runs as part of the main loop. In state UART_IDLE it's waiting on a command UART_CMD a command has been sent. IF that command expects a parameter byte, it stays in UART_CMD if not it jumps to UART_BUSY If in UART_CMD and a byte comes in it goes into the uart_data value (parameter byte) and then state changes to UART_BUSY.
There is never a state where more than 2 bytes will be sent to the PIC, so if it's in UART_BUSY and data is sent, it's ignored, and the flag is cleared. At least that's how I intend for it to work.

Yeah I should write some UART error routines, but this was just my first pass of the UART code, just wanted to get it working for a basic 'Hello World' case (send a byte to the pic, have it respond with a string). But that's not how it's working out since the received byte is not making it through.

The Rasberry Pi is probably running inverted data for connection to a PC, but your PIC is running true data if you are not using an RS232 buffer. The PIC does have a bit to invert the TX signal in hardware, but you would have to invert the RX signal with an external buffer if this is the case.. Jackson 5 Anthology Rar. Florin.matei You could try using MPLAB Code Configurator (which is a plugin for MPLAB X) to generate the driver for the EUSART and try to use that one.

Besides generating the EUSART driver you can quickly set up the part and other peripherals.
It's a 16LF1527.with no other peripheral functions on his TX1 pins! If he can't read the Data Sheet and get the freakin' EUSART going then he's going have loads of fun later on.and be right back here asking questions. No amount of hiding behind some silly candy-wrapper software is going to save him then. You guys need to focus on: - continuing to make really cool chips - pulling your head out of some corporate bean-counter's a$$ and make the fully-optimizing compilers free (so you can sell lots of those really cool chips - that is your business model anyway, right?) - making MPLAB X less of a steaming pile. A voltmeter will tell you if it is inverted or not. Non-inverted is normally high and pulses low for data. Inverted is normally low, pulsing high.
