Published Date: 01/08/2007

Description

The TMS470 family of ARM7 microcontrollers contains a RISC coprocessor referred to as the High-End Timer (HET). The HET can implement complex I/O operations independent from the CPU one of which is the capability to generate PWM signals. This application report describes using this PWM capability along with an open source voice algorithm called Speex to encode 8-bit voice messages without the n
