What is your development environment? That might make a big difference on which programmer to use. Avrdude, which comes with the WinAvr (GCC C compiler) works with a variety of programmers including some "no parts" ones like the SAMPLE programmer I supply with my ARC boards (www.

Hi Dave, Checkout http://www.futurlec.com/ATDevBoard.shtml I bought my AT90S2313 developement board from them for $19.90 which will allow you to connect a LCD display and other things to it. It comes with a CD and cable. This will only flash the Atmel AT90S2313 but for the price

My recommendation is to get a STK500. They're about $80 at DigiKey (http://dkc3.digikey.com/PDF/T042/0294.pdf). It supports a wide variety of chips and serves as a simple test bed (lights, switches, etc.). Its ISP programmer can also be used to program your AVR in its circuit sim

Hi All, I have been reviewing the archives to get an idea of a simple way to program some chips. As it is now, I am just getting started and an not looking for the most universal, but the best cheap unit, even if it limits my chip selections. I'm hoping there is some simple progr

The Atmel AT43USB370 and AT43USB380 can serve as USB hosts. There is a fair amount of software involved, but it can be drastically simplified in the data logging application described if you decide you only want to talk to mass storage-class devices (such as the USB key drives) a

for simplicity, people using 8 bit micros often use compact flash (CF) cards to avoid the complexity of USB. There are implementations of CF interfaces on the forums of various micros.

In ponyprog (checked = programmed = 0) Erased fuses read 1 like any other eeprom location. I believe you'll need an external clock oscillator fed in the mcu, just an xtal won't do it. After you re-program the fuses, you can set any option you want. -carl At 04:39 AM 7/19/2004, yo

There really isn't any need to store the data in a control. Why don't you just write out each byte to a file as you receive it? If there is no need to display the information, don't bother putting it into a control. Good Luck, Ken www.speechchips.com --- In AVR-Chat@yahoogroups.c
