Comunicación Serial (UART)

Los PIC utilizan, entre otros, dos modos de transmisión serie:

• El puerto serie síncrono (SSP).
• La interfaz de comunicación serie (SCI) o receptor transmisor serie síncrono-asíncrono universal (USART).

USB HID CCS DEMO

Well, some weeks ago I was thinking about, what can I post?, so I saw around my study room and I saw my old toolbox with my old development boards, for example my Pinguino32, Arduino, Stellaris and other boards that I made when I was studying my career, and among these things, I found Microchip's microcontrollers PIC16fxx and PIC18Fxx. Of all my microcontrollers that I found and I had one with USB interface, and this it's the reason why I made this post talking about USB HID.

Human Interface Devices

History of the Universal Serial Bus (USB) is quite short compare to RS232 for example. Development started in 1994 by effort of six companies - IBM, Compaq, Intel, Microsoft, NEC, Nortel and DEC. The first idea was to develop universal bus simple to use with small and compact connectors (to reduce many connectors in the personal computers). To have a possibility to connect devices such as digital cameras, webcams (or any other devices with big data transfers in a short time), there was also requirement for high transfer speeds.
