I have werked with the PIC's and AVR and also have a 68HC11 dev board, it is a bit dated now, but I still use it now and then, but as I am fairly new to the micro, am struggling with many aspects. I have a bunch of devices, many hc08,908 etc that I would like to be able to program. I ahev read a coupld of posts regarding the subject, and found that the chips can be programmed easily via serial and max232, but wonder if this werks for all versions, or just a couple? What about when I want to use hc12 devices? Any help with a good design, link whatever would be great!!!
