Orientador: Prof. Djan de Almeida do Rosário, Esp. Eng. Palhoça 2018 Dedico este trabalho а Deus, por ser o verdadeiro princípio e fim de todas as coisas (das que valem a pena). AGRADECIMENTOS Agradeço a minha esposa Gizele e meus filhos, Eric e Thomas, meus pais e a toda minha família que, com muito carinho е apoio, não mediram esforços para que eu chegasse até esta etapa de minha vida. Agradeço aos professores do curso por terem transmitido seu conhecimento a mim e meus colegas com tanto empenho e dedicação. Não existe triunfo sem perda, não há vitória sem sofrimento, não há liberdade sem sacrifício. (O Senhor dos Anéis – J.R.R. Tolkien, 1954) RESUMO A crescente demanda pelo desenvolvimento de solução conectadas entre sistemas já existentes, assim como a ampliação do uso destes sistemas embarcados mostram a importância de soluções robustas, de tempo real, com ciclos de desenvolvimento cada vez mais curtos e necessidade de reaproveitamento de código. Este trabalho apresenta a seleção do sistema operacional de tempo real FreeRTOS e o experimento de sua utilização como base para o desenvolvimento de um controlador wearable (vestível) em duas plataformas de hardware diferentes, implementando a solução inicialmente em uma delas e depois portando para a outra plataforma, desenvolvendo principalmente a programação específica do novo hardware e procurando manter a parte da aplicação inalterada e independente de plataforma.
