Debugging blues
I have had random communication problems (very slow programming and then errors on verify when programming) using both stk500 and JtagmkII. It seemed to be my serial port as...

Registers R00...R15 instructions that can use list
My bad, you are indeed correct, I do have one bad eye and the other one is not so good either. I see under other documents is the link for this pdf. I Thank you both.

Registers R00...R15 instructions that can use list
Glad I asked. I see the LDI instruction specifically says R16 thru R31 on that sheet so I will make the assumption if an instruction does not specifically say the registers it...

Flakey serial port
Yes I can erase, program, read signature bytes, but the verify runs into the ISP FREQ error. stk FREQ is set at 3.686 Mhz ISP is 1.202 KHZ It just did it now, erased, programed,...

Messy wires
I am making a board with a ziff on it to hold the tiny45 and others that use the blue socket on the stk500. The plug will go into PORTB pins on the stk500 and the board can just...

Messy wires
Would this not be just like a printer A/B switch? perhaps an analog rotary switch to select the routing of the signals or lots of transistors and one onboadr uC to accept input to...

Messy wires
I would pay $250.00 U.S. for such a board, heck I just spent 300 on the JTAGICEmkII and the better I get at programming the less I will use it. On the other hand the better I get...

DDR and port setup for ADC
Thank you Alenze, I now have a working ADC circuit. Things I had to change: PortB2 ADC1 pin7 ATiny45 simply will not work so I used ADC3 PB3 pin 2 My logic was flawed for output...

Calibrating Temperature on-chip sensor tiny45
Hi Sceadwain. Yes I think you are correct as you put it for the initial calibration point. Having to calibrate them could take too much time as we are looking at a retail item...

Calibrating Temperature on-chip sensor tiny45
Yes, Koshchi you are correct, actually I thought the scales were non linear but that was only because I calculated the subtraction in my head to 8 instead of 18. So it was not a...

Problem with STK500/JTAGICEmkII reprogramming after debg ses
You should help ATMEL with their documents because the way you put it I can understand. I will try that tonight when I get back home. Thanks for the information and the time, I...

Calibrating Temperature on-chip sensor tiny45
Indeed it is not clear. for example if you get a reading of 40C it could be 30C or 50C thats 10C on either side. Then it gets more complex as 40C=104F 30C=86 (18F difference on...
