This is probably a dumb question, but I have not found a definitive answer to it:
As I understand things, a bootloader, which must be programmed onto the chip beforehand is required to program the HC08 series while in user monitor mode, which is the monitor mode that does not require an external clock and the high voltage Vtst.
It is also my understanding that if you do have the external clock and Vtst, you can program the chips without a bootloader (ie if you had a completely blank chip)
is this correct?
Also, does the QY series come with this bootloader programmed in from the factory?
Thanks!
I have heard this about the monitor mode being error-prone and unreliable, but haven't had the chance to play with it. what is so error prone about it, and why?
also, is there a cheap and easy way to build a programmer for the HCS series? I have seen a few things about an "open" programmer for them, but haven't really investigated. anyone have any experience/thoughts on that?
Dear Voltaic,
You can check this discussion board for Open-source BDMs for the HCS08/12.
