16  Using Arduino / Microcontrollers / ATtiny45 vs 328P using Arduino ISP on: April 20, 2013, 04:55:43 pm
I'm a tad confused on some of the Arduino as ISP stuff.

So far I can program an ATtiny45 just find as ISP using these pinmappings:

SCK   > Digital 13
MISO   > Digital 12
MOSI   > Digital 11
RST   > Digital 10

VCC   > +5V
GND   > GND

I can burn the 8MHz Bootloader and the 1MHz one, uploading sketches works great also.

Now all the diagrams to do something similar with a 328p show using a jumpered 10uF cap across RST and a crystal.

Is there something different in the way the 328p behaves that you need the hardware?

I don't have any crystals and the closest cap I have is a 100uF or a 100nF
17  Using Arduino / Displays / Screen from a cheap cell phone on: March 10, 2013, 03:03:13 am
Target in my area is selling a Samsung M270 flip phone for $5 USD. I was intrigued by the price and possibilities for parts. It has a color internal LCD of about 1.7 inches I believe, and an external LCD that's 1 inch. It should also have a battery and charger.

I see a lot of nokia LCDs for sale to use with Arduino and was just wondering if it would be worth the trouble to try one of these.

The screen is 160x128 and has a 480MHz QSC6155 cpu in the phone.

As frequency goes up, range and penetration goes down in most cases, however bandwidth capability does tend go up with frequency.

Which is one of the reasons why shortwave (single digit mhz) radio has such good range.

Worst case scenario, you could pull the pedal off, and connect a servo to the pot and have it rotate it. It would be a much slower effect though unless you got a really good, fast servo.

I'm wondering if somehow the read pointer is getting advanced so when there's some actual real data there, the part where it checks for the beginning of the fame is 2 bytes ahead. So on the off chance after a few hours it lines up again it appears to start working.

Just a guess. I'm more of an understand the logic guy than a programmer.

The chip James is referring to is that small ~5mm quad flat pack chip near the USB port on the board. It just acts as a bridge from the 328 to the USB.

The high voltage could have flipped a few bits or fuses around inside the chip or the USB controller. The chip may be ok but possibly would need to be flashed in a programmer.

Though it may be cheaper to just buy a pre-programmed chip. You'd need a 328 chip with an UNO bootloader.

You could use a 328 flashed as a Duemilanove but you'd have to set your board type to Duemilanove when uploading to it.

The typeface being wrong on the silkscreen was the giveaway to me.

A real uno will have the box and stickers with it, and the made in Italy thing on the back.

You could always pick up one of these and use it to reprogram your replacement chip.  Now you've got two boards!

Mine was real, bought through amazon. Came sealed in the Uno R3 box with stickers and everything.

I guess you could file a bug report to the Arduino people saying that your device didn't immediately catch fire like it was supposed to.

One of my 'knock off' boards has the socket, and therefore the notch, the wrong way round!



All sales are final!

My board has the notch silkscreened on it, as well as the socket has a notch, as well as the chip having a notch.
