Based on MSP430 pronunciation and audio frequency compression/solution compress technique
Friday, November 28th, 2008 at 00:35 | No commentsCategories: SCMShort Content: Introduction Uses micro controller (MCU) to implement the pronunciation recorder to be quite simple. Many MCU uses the integrated modulus (A/D) switch. The loudspeaker will catch the sound provides to the amplifier, then presents again gives a/D switch's analog input. May the sound which records save, in dodges saves or memories and so on RAM, presses down the button to be able to trigger the sound which MCU broadcasts records, its principle is the data which saves provides first ... -
Micro controller management power source sorting and control
Monday, November 17th, 2008 at 18:12 | No commentsCategories: Power SupplyTags: MSP430Short Content: Along with the double voltage architecture and the multi-processor board's rapid popularization, possibly needs several processor voltage skeleton line including the simple application. Because each processor has own Canada and the power failure request, power source skeleton line sorting and the control turn a complex duty. The power source designers face the challenge is needs to consider that each processor fixed time with the voltage request, and buys in these requests in the overall system, guaranteed that designs finally satisfies ... -
