This library provides a fixed-size FIFO to an application. Users can set the FIFO depth and width. There are also three examples for mikroPascal PRO for PIC, dsPIC/PIC24 and PIC32. Each example implements a USB CDC device and a PC application sends commands to PIC for adding/reading items to/from FIFO.

Features:

 - Fixed width and fixed depth

 - Width and depth are user defined as constants

 - FIFO size is limited only by processor architecture and available memory

 - Code can be further optimized for small processors or reduced memory

 - Items can be added to FIFO from one thread and read from another thread

 - Uses static memory allocation

 - Compiler directive for FIFO event handlers (e.g. FIFOFull, FIFOEmpty, OnAdd, OnRemove etc)

 

Requirements / Recommendations:

 - If using interrupts to add/read items to/from FIFO, the event handlers can be used to temporarily switch off interrupts in order to avoid reentrancy or calling adding/reading FIFOs while executing one of them.

 

Limitations:

 - Does not allow reentrancy

Misaligned Address Finder

1

Misaligned Address Finder is a tool used to generate a report on variables and constants, which are not Word or DWord aligned. Some variables / constants are required to be allocated at even addresses (16-bit architectures) and at multiple by 4 addresses (32-bit architectures), so users can be notified about that allocation.
