Oh, MAN, that's a good link! People are asking this question ALL THE TIME about AVR's and PIC's -- and now here's a definitive answer! So yes, this link gives you the technique. First, you open the package. In their case, they used a smart-card, so they removed the CPU core from

Thanks Bruce, I was aware of the 2 pages devoted to this in the current Tiny13 and Tiny2313 data sheets. I don't want to debug, I just want to be able to program the non-volatile memories via the 1 wire interface as they are promising on page 92. > Check page 92 of the current AT

Does anyone have information on the debugWIRE interface. The 2 pages in the Tiny13 datasheet are only enough to tell me that it exists, but are inadequate to actually design an interface or write code. I've searched Atmel's appnotes and all of the datasheets of their other device

We solder 16 pin headers onto LCDs all the time. Perhaps your soldering temp or choice of solder is the problem? Al Welch -----Original Message----- From: Adam Bradley [mailto:adam_j_bradley@yahoo.com] Sent: Sunday, November 30, 2003 7:20 PM To: AVR-Chat@yahoogroups.com Subject:

Umm, are you soldering to the contact areas on the glass?? I believe that the proper way to make contact with a glass LCD is with a "zebra strip". Googling for the terms LCD ZEBRA STRIP brings up some information. Have Fun! --- In AVR-Chat@yahoogroups.com, "Adam Bradley" wrote: >

Hi! After a short hiatus (house painting, travel etc) I'm back trying to get my LCD to work! After soldering a couple of jumpers on a board with some pitted tracks, I _have_ managed to get the LCD to work. However, not reliably. My issue now seems to be soldering the SIL header t

Hi Mark, I don't know these optos but, as a general rule, there are two things to watch out for. Current Trandfer Ratio (CTR) and speed. CTR is a bit like bipolar transistor beta - it is the ratio of output (collector) current to input (LED) current and is commonly as low as 20%

Absolutely – if you develop your application with the ISP header on the board, then you don’t need STK501 to program it – just use the STk500 with ISP header as per normal. Hope that makes sense J From: Steven Chang-Lin Yu [mailto:stevenyu@powerup.com.au] Sent: Wednesday, 26 Nove
