I have several questions regarding K185. This looks quite attractive: USB powered, variable Vpp and Vdd, firmware upgradeable through Web, built-in SMPS, design for production, ICSP+ZIF socket. 1) How about the chip support? Can it program dsPICs? 2) Am I right to assume Vpp and Vdd are automatically controlled once the right chip is selected? What is the range of Vpp (9V to 15V or even wider)? What is the range of Vdd (1.8V to 5.5V or even wider)? Does it have alternative supply input other than USB? 3) Any information regarding the target retail price (<=US$100? without the long USB extension cable)?

Subject: Re: [PIC] PIC programmer performance comparison, etc I designed one for Peter C (DIY electronics), the K185. Both VPP and VDD are in 0.25V increments, and it operates from the USB port, with a stepup/stepdown switcher set, allowing USB V-level as low as 4V. It is intended for production useage, with a throwaway socket, etc. Uses PIC16F88, and the firmware is upgradeable via the web. I plan it to be operable with those long USB extension cables (100ft+) so it can be dragged over the production floor. Of course, it drops its power when unused. It is waiting for me to release a new programmer protocol before it can be firmed up and released. I think it can go out in Feb 2006 if not before. --Bob -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
