updating mpguino?
Hello all,
I'm going to buy the preassembled version of mpguino soonish. Is there any way for me to update it, or will I have to buy a new chip each time there's a new version? Thanks for your help in advance! |
The preassembled does not use a bootloader anymore for reliability and space reasons. You can reprogram it, because it is just an atmega168 chip in a pdip socket, if you want to get fancy, but the preassembleds mission (and mine) is simple and reliable fuel consumption feedback. You can swap chips with a pdip arduino or use an ISP programmer and adapter. I have a special adapter I made that just pushes onto the chip sitting in the socket and program it with a usbtinyisp. many many many options there, but not something I can support en masse.
I have been offering to reflash for six months from receipt provided the users pay shipping both ways (i.e. S.A.S.E.). avrfreaks.net is a good resource as well if you want to learn more about isp programming. |
How to reprogram MPGuino?
Hello Singletree5990,
Very interesting way of calibrating. However, I am writing to you for the very last part of your posting: if one want to change part of the program of MPGuino, is there a way to do so? I donīt see any port on the MPGuino board I got. Is it necessary to get the chip out and plug it into Arduino, or what? Thousands of apologies for the question.... :confused: -------------------------------------- Quote:

Beaver, you have a prebuilt, single is using a kit from spiffie (different animal). The prebuilt is not a "development" board, It is meant to "wire it up and go". But nonetheless the chip can be reprogrammed in a variety of ways. I won't go into detail (that is what AVR Freaks is for as well as Arduino - HomePage ) but I will offer the following.
for hardware I use a homemade adapter like the one pictured in this thread: http://ecomodder.com/forum/showthrea...er-7311-2.html and a usbtinyisp (google). And I can reflash a chip without needing to use space for a special onboard isp connector. And compiler is gcc what came with the arduino 0011 installation. But understand that it is not my charge to teach people how to program atmegas. It is not such a simple thing to learn and requires some hard work and dedication and many options to sort through. |
Prebuilt MPGuino
Understood.
Tks, some questions on other message. Quote:
