Questions tagged [pic24]

PIC24 devices are general purpose microcontrollers, manufactured by Microchip Technology.

The PIC24 devices are Microchip's first inherently 16-bit microcontrollers with some significant enhancements such as all registers being 16-bit, 64K data address space, 24 bit wide instructions, hardware support for loop indexing, etc.
