Hi I have an optical sensor. It triggers an emitter and reads a response from a photodiode and amplifier. after firing the emitter, I wait until the amplifier has had time to reach a stable output - say 5us - then I initiate an ADC conversion. Now, If I turn off the emitter too s

Yes, 100khz (although I have tried from 10khz -> 500khz with identical results). There is no "speed" configuration for the AVR since they are in slave mode only (except when I make one a master for testing purposes...) ----------- Larry Barello www.barello.net | -----Original Mes

Ok, I have determined that the problem has nothing to do with the ARM / AVR interface. It is the level shifting chip (PCA9512). Well, at least it appears to be that: if I remove the level shifter and power everything with 3.3v then communications work. The symptoms are simple: On

I am trying to interface some AVR boards to an Arm9 board (Atmel at91RM9200 @ ~60mhz). This worked at one point but now it isn't and I am getting stumped. There appears to be ~200ns of delay between the SDA and SCL when generating the START condition. This seems too small for the

You are not likely to get much help with avrora here. I've never seen anybody refer to it on this list. Of course, you are welcome to ask, but please don't be upset if nobody answers! I have also never seen it referred to on the avrfreaks list. There are a lot more folks there, h

I'm in mid-stream, porting an app from a T11 to T15. I've hit something really odd, and it is not showing up in sim, only in the real chip. I use a couple of table lookups through the Z register. It appears that the data I get back isn't what's in the table. Is there something I'

Ok, for what it's worth, it IS in the STK-500 user's guide under ISP Programming. What I was looking for was "socket selection" which is right above that, and tells you essentially nothing about selecting which socket to use, almost as if it should have been a link to the part in

Actually, if you used a compiler that created re-locatable code you could store the compiled results a form of library and pull them in and store them in FLASH using the same routines that the bootloader uses. You then jump to the "overlay" page and execute from there. You'd need

I have another similar problem with my GCC ported butterfly: I need 4 output pins to eventually control a stepper motor, but for now I'm playing just with LEDs. So first I tried to use PORTB0-3, but only 0, 1 and 2 went HI, and even those, not as I expected (not one at a time). T
2006-04-12 by kernels_nz
Hi Guys, I have not worked with the butterfly myself and to make things even worse, I dont even know what type of up it's got on it. But from the conversation, the only thing that you might want to have a look at is to make sure that JTAG is disabled (in the fuse bits). Otherwise

first of all you need to define your HMI. basically HMI is an interface to humen. so you need to display things on a visualisation device such as graphic or text LCD, or even a monitor. then you need to get user choices, using keypad, keyboard, mouse, etc. after all you need to d
