Hi - I am working on debugging a CAN bus. Problem is, I've never used CAN before, so I don't even know what correct communication should look like! Does anybody have images of what the data on the CANTX and CANRX lines should look like (the...
Hi - I have posted previously on this issue. I pretty much had my CANbus working today when I decided to mess around a bit with thetermination on the bus, forgetting that the board was still running.Anyways - after that I was getting pretty...
I need an 80MHz 32 bit microcontroller with an ethernet mac.Can I get one for less than $7 (quantity 1k)?Alan Nishioka
I'm trying to select a microcontroller for an application, and havinglittle luck sifting through the masses of information on the web.I need:1) Two async serial ports, capable of running at 9600 BPS. I'd greatlyprefer this to be in...
Hi - I'm trying to interface a 3.3V ARM (Atmel AT91SAM7X256) to a 2.8Vaccelerometer (Kionix KXP-74) over SPI. The ARM is the master. So -tell me how much I'm off here: I was thinking I could use a simple2-resistor voltage divider for the...
Hi - I'm currently using an Atmel AT91SAM7X256 to do a large amount offloating point operations (mostly multiplies with a decent amount oftrig as well). It does OK - but my floating point needs are soon goingto be expanding (by about...
