Hallo I am PIC programmer. I have always used CCS C compiler. I want to pass to the 32 bit platform and I thought that ARM would be best. I thought of buying a development board from Olimex and use the Keil uVision compiler. Before spending a few money I need to clarify a couple of things. Do I need anything else to get started? Is the Olimex board and Keil compiler enough to write firmware, compile, burn the chip, and expect it to work? What is the jtag? In CCS C compiler there are many libraries for the microcontroller’s peripherals, is it the same in ARM development?
