Re: Microcontrollers????
The are a whole range of MCUs for which a C xcompiler exists.
Atmel, Microchip, TI, Silicon Labs, Digi, Freescale, Hitachi, NXP and Intel are just a few of the companies that manufacture at least one MCU family which can be programmed via C xcompiler.
You typically develop the C program on a desktop computer using a cross compiler or xcompiler, the MCU is then programmed using JTAG, BDM, COP, ISP ICSP or some variant of one of these programming/debugging interfaces.
It would be beneficial to know your final application or if this an educational pursuit, before recommending a particular MCU.
Each different MCU family has it's weak and strong points, so knowing the final application would help narrow the field of recommendations.
