We are going to operate our PIC in 3V3 mode. Those are 8bit mid-range microcontrollers. But it should be possible to adapt to any PIC microcontroller with required peripherals. The presented application may be also reused in other project during development even if the final system will not have any LCD.įor the development the PIC16F18855/75 was chosen since it has most of the peripherals used in our previous projects. This is why we’ve chosen to make the first example with an LCD. When developing an embedded system one may have the need to have some output, e.g. This may have a couple advantages: custom PCB fitting a certain casing, only used peripherals, much lower power consumption enabling long-term battery powered systems, etc. If one wants to make a step forward and convert his/her prototypes into real product an embedded system comes in mind. Both Adruino and Raspberry come with a ready-made PCB where all those peripherals reside and consume power. This means, e.g., the need to boot for a couple of minutes. In case of Raspberry Pi it is a full-blown computer with all common peripherals, operating system, etc. While Adruino and Raspberry Pi are great prototyping tools allowing fast development of proof of concepts, lot of resources, libraries and examples, it also comes with some pitfalls.

A device programmer consists of a hardware and a driving software. To burn a chip you need a device programmer. The name of the file should be USARTTest1.X.production.hex Burning the hex file to MCUīurning is the process of transferring the data contained in this hex file to appropriate memory locations on the chip so that chip can execute this program.

The hex file which is actually the executable program in machine language, is generated in the folder " \dist\default\production" which is in your project folder. To build the project select Build Project from the Run Menu.

This executable image is in the form of a hex file. Building is the process of compiling all files in the project and then linking them to build the final executable image. Get the amount of data waiting in USART queue
#MPLAB XC8 LCD H SERIAL#
USARTWriteLine( "This checks both way serial transfers.") USARTWriteLine( "appear on serial terminal.") USARTWriteLine( "For example if you type 'a' you will see ") USARTWriteLine( "PIC MCU will return the same character but ") USARTWriteLine( "it will reach the PIC MCU via the serial line") USARTWriteLine( "Type a character on keyboard")
