After several intsruments built with the 6805, I'm looking to upgrade to a more modern processor with more code space and RAM, as well as more modern debugging schemes. The 6808 series seems to fit the bill, specifically the GP32 chip.
One of my biggest hangups about the 6805 is the ancient and poorly supported debugging/emulator tools (I use the Cosmic compiler which I DO like). After my emulator apparently died, I'm hesitant to put in more money toward the 6805 tools.
The Cyclone Pro product from PE Micro looks like a very useful tool.
Is it reliable? Is the interface software stable and reliable for both programming the flash and remote debugging through a MON08 port? How's the support from PE Micro? Does the MON08 debugging capability provide enough info to be useful during the first stages of product development and bypass the need for an emulator?
Your input appreciated.
Also, a technical question: the datasheet for the 908GP32 seems to indicate that it is not possible to use a 4 MHz crystal for the clock such as is possible with the 705C9A. One must either use a 32.768 kHz crystal and the PLL feature to synthesize the clock (and implement the external filter), or use a CMOS level oscillator? Is this correct?
