if you want an 8 bit reading for the accelerometer it looks to me like you can just read the 3,4,5 bytes. and not bother adding the extra 2 bits from the 6th byte to the reading.
Anyway im happy to see i can repeat what i found last night. it looks like a nice way to get a joystick for a project. its a pitty about the connector.
option 2 is not a programmer, it is just an adatpor to allow you to program standalone chips with either the icd2 or pickit2 etc.
i own one of the sureelectronics pickit2 programmers (not the icd2 like you linked) and it worked great for about 3 months then something happened and it no longer works. so i ended up buying the original pickit2 from here http://www.microchipdirect.com/ProductD ... ry=Getting Started Programmers&mid=13&treeid=6
worked flawless ever since.
im not saying the sureelectroincs stuff is bad as i only have 1 to go off, but i just wanted to mention what happened to mine.
yes i was thinking that i had to use the pullup pin to connect it to the signal i wanted to pull it up, not connect it to the power supply rail to pull them all up. my mistake.
im thinking that the pullups arnt needed anyway, i just disconnected them and it works fine still.
and my mistake with the address was i assumed the address was bits 6-0 not 7-1 with the r/w but being 0. it makes sense now.
this would make a nice easy tutorial btw. if you can get ahold of one of the breakout boards.
so i need to manually connect 2 pull up wires or doesnt it need em?
also i found http://svn.stuytech.com/public/nunchuk_read/ what confirms your addresses . maybe ill have to check it in the morning. its after midnight and im not thinking straight.
i have to say that if you want a microchip programmer you cant go past the genuine microchip pickit2, @ about $35 its cheap as, it works very well and for the price i dont think its worth buying the clones (been there done that).
It can basicly do everything that the icd2 can do including the debugging and more. the icd2 is quicker at debugging from what i hear but i havnt really got into that side of things so im no expert.
it can be bought from the normal places (mouser, digikey etc) as well as from microchip direct as well. get the programmer and pic up a few spare chips at the same time .
So if you have the money the icd2 is great. but if your on a budget get the pickit2 would be my choice.
just a quick not that this board seems to be a slightly different layout and doesnt require the jumpers mentioned in the post. except for maybe the resistor jumpers if you run fets.
Also i couldnt find R8 on the parts list. i had to check the schematic. its the same as r7 , 10k ohm according to the schematic.
anyway i hope that helps someone.
i still have a few bits to add being i was short in my parts box. but a couple if regulators and some fets and i should be done.
yes it does look like a well done home made board.
I must say i was impressed how easy the board is to make for what it is. sure you need to be carefull but there is nothing on there most people couldnt do.
The SD card was probably the hardest from memory and even that isnt to bad.
