Code:

• Atmel's FatFS Wrapper

  Atmel includes in its Atmel Studio an implementation of the FAT File System by ChaN.

  The package works quite well, unfortunately its API is a little weird, the functions have different names and types of arguments than the standard C or POSIX implementations.

  This wrapper fixes that.

• Mutex

  A simple but efficient mutex implementation for FreeRTOS.

• FlexiQueue

  A novel queue implementation for variable-size elements.

• Expression Parser

  Simple expression parser suitable for PICs (no recursion), but works with any platform.

• MATH_DATA & .tmp_data save/restore for FreeRTOS

  Solves problem in FreeRTOS port for PIC18 with Microchip MPLAB-C18.

• Generic Pointers

  Pointers for Microchip MPLAB-C18 that may point to RAM *and* FLASH memories.
  No need to have four different versions of strcmp anymore.

• SimpleRTOS

  Simple RTOS for Microchip Baseline and Midrange MCUs.

  *New(2014-02-10)* Simple RTOS is now a real RTOS. The port for PIC32 (MIPS 4K) is available here.

• A co-routines framework for small microcontrollers.

• Heap Management For Small Microcontrollers

  Heap management for PICs, mostly PIC18 and FreeRTOS
  

• Hi-Tech memcpy

  This routine is a substitution for the one in the Hi-Tech PICC compiler library

• Simple Perl script for formatting code

  This script formats source code listings for posting in the site

• LCD routines

  Routines to control an HD44780-based LCD module emulating a tty screen

• Core-dump

  A core-dump implementation for PIC18 devices with on-chip Ethernet controller

• Image rescale algorithm

  An image rescaling algorithm that doesn't use floating-point and fewer multiplications than more traditional ones

• Rotate a byte a variable number of positions

  Rotates from zero to 7 positions, takes only 8 instructions and is isochronous

• HX711 routines

• 1-Wire/iButton routines

Circuits:

• Simple power on/off circuit with one transistor

  I created this circuit some years ago to soft power on/off circuits with PICs (the ones that have open drain RA4 and input-only RA5)

The source code you posted here looks like it might help me quite a bit.
Thank you very much. " +

Questions:

• Waldyr Yassuo Kamakura asks:

  Isaac:
  Estou estudando um pouco o FreeRTOS e observei que vc. publicou alguns melhoramentos sobre esse RTOS. Vc. poderia me informar se esses melhoramentos foram incluidos nas novas versões?
  

  Isaac Marino Bavaresco replies: Waldyr, eu nunca publiquei as mudanças que eu fiz além do que tem nessas páginas. O autor do FreeRTOS não é muito aberto a sugestões e algumas das minhas ideias não estão de acordo com as dele. Saudações, Isaac +

• Ilton L Barbacena asks: " Oi Isaac, Ainda anda trabalhando com microcontrolador?"

  Isaac Marino Bavaresco replies: Olá Ilton, Como vai? Quanto tempo! Sim, ainda estou trabalhando com micro-controladores. Também estou fazendo mestrado em Ciência da Computação na UFG. Me escreve diretamente pelo meu e-mail isaacbavaresco@yahoo.com.br. Abraços, Isaac +
