Estimados:
Intentando ver por donde puede llegar a venir el problema, hice otro proyecto en el cual, no uso el USART, sino que cargo manualmente un arreglo de 30 y lo recorro para compararlo con un caracter, y estoy teniendo el mismo problema.
Adjunto todo el código para ver si se puede hallar el problema.
