PIC Microcontroller Embedded Development Using the CCS PIC MCU C Compiler – Day 3

There are embedded applications that do not require the device to connect to the Internet. However, most every embedded device is required to communicate with something whether it be another embedded device or a personal computer. When dinosaurs roamed freely, RS-232 was the preferred embedded device intercommunications method. The dinosaurs are gone and RS-232 is alive and well. Despite RS-232’s continued usefulness, USB has come to the forefront of inter-device communication. In the case of embedded devices, USB offers features that RS-232 cannot rival. USB is faster than RS-232 in most cases. USB can support multiple devices on its bus. And, in most cases, the embedded device can be powered directly from the USB bus. The CCS PIC MCU C Compiler supports USB on PIC microcontrollers.
