Well I personally have Mega32, Mega1284p, Tiny45, Tiny85 but am thinking about getting some more Tiny's for really small projects.

Has a price been announced?

I know the chip uses the speed of the clock (either internal or external crystal) to time other things like delays and pulses.

If you wrote a program for a 20mhz chip for example and then dumped it into an 8mhz chip without fixing that in code, you may have timing problems, like the pulses to the servos are not correct because you're only running at 40% of the speed.

I found this out uploading a blink sketch to an attiny that was using a 1mhz internal clock. I thought it wasn't working because the light wasn't blinking, turns out it really was but the pulses were like 16 seconds apart because the clock wasn't compensated for.

In AVR C you have to set you chip speed at the beginning. The arduino IDE by default assumes you're just using the board speed.

When you're programming your other chips, do you have a separate entry for them in the target board with the speed set correctly?

Was that big scratch already there?

The easiest thing to do is buy a pre=programmed Atmega328p-pu chip from Sparkfun, Adafruit or one of those sites. If you buy a bare chip, you'll need the bootloader on it which you won't be able to do without a programmer or another functioning arduino.

Adding it through Legacy hardware is not going to work. We need the hardware ID to be sure.

Do you know this is an official Uno R3 and not a clone? If it is, it may be using different guts. An Uno should have 2 Atmel chips, the big one in the center and a really small one near the USB port which controls the USB connection and provides the USB serial port.

You're going to have to delete that com port because when you get the driver installed correctly the unknown device will move up there as a com port.

Anyone had any luck getting this to work on 1.5.2 ?

1.0.3 sees them but 1.5.2 doesn't.  1.0.3 it scrolls off the screen and I can't select them all so I want to try 1.5.2 to see if it is fixed since I'll be using some bare AVRs to program.

I got a few chips as samples from Atmel.  You'll need a 16mhz resonator or 16mhz crystal with 2 22pf capacitors and power to vcc and ground to gnd.

If you search on LCDs on aliexpress and sort by price, there are more LCDs that are about 50 for a dollar or two.

I googled the part number and they are 12.1" screens.

Hmm.

Ok results:

Putting the 328p into the Arduino did work when I loaded the blink sketch on it.
Trying to flash the never-been-touched 328p just got me a sync error.

Ok, so I've got a couple of things to try.
1. Try the 328 that wouldn't program in the arduino itself to see if it will take a sketch.
2. Try the 328 that I've never removed from the packaging to see if it will take a sketch as is.

I find it interesting that it doesn't need the cap for the ATTiny.
But with the cap nothing gets programmed.

Does the 328 that has never been programmed before work without a crystal like the ATTiny does?

Ok tried the 328 with the Arduino as ISP sketch and it programmed it into the chip on the board.

I put the 100uF across rst and gnd and got a sync error when programming.

Well I'm using the Arduino as ISP sketch on a Rev 3 Uno.

I'm curious also.  I have a 40 pin PDIP 128 chip that I'd like to put to use.
