Re: Design Pulse Oximeter using wireless bluetooth

Posted: 21 Dec 2012 01:35 AM PST

If you can tell us what you've done so far, we might be able to give better guidance.

Are you using an existing oximetry sensor? How is it connected to your Arduino? What sort of interface does it provide?

Which Bluetooth module/shield are you using? W...

A good example was the 8088 CPU.  It had 16 bit registers.  8 bit data bus.  20 bit addressing bus.  They called it a 16-bit micro but any of these might have applied.
Not really.  A CPU is an 8-bit CPU if the width of the "arithmetic an...

Quick question about populating arrays

Posted: 21 Dec 2012 01:34 AM PST

This is probably a silly question but I can't seem to find the answer.......

Code:
typedef struct {
  byte  a;
  byte  b;
} button_t;

button_t values[10];

Is it possible to populate the values in one of the array elements like this:

Now that was fantastic  smiley-cool

Gives me a reference to see what is going on, problem has been that the LCD library does not give the information I needed, but using hex is a cool way to keep it from becoming bloatware!

Thanks again

Re: Atmega8A-AU & Atmega328P-AU Optiboot Bootloading Help !!!

Posted: 21 Dec 2012 12:59 AM PST

Optiloader itself runs on your existing arduino, which needs to have at least an ATmega168, since the sketch is 13k long (because it contains copies of three different optiboot_*.hex files, including the one for ATmega8.)

Da bleibt Dir nichts anderes übrig als ein Array zu verwenden.

because the Due is based on an ARM processor and avrisp is not compatible in any way..

Hi Again Coding Badly,

I've just checked, removed the chip, put into an official UNO board and successfully reprogrammed, so the bootloader is OK, the cable is OK, unless there are different drivers or code running the cable during the programming of t...

Hi

If you'd be wanting to create a int searchSerialBuffer(char * searchTerm1, char * searchTerm2) which would search for the first occurrence of either term, and return a value for which it found, that's entirely possible.  The only caveat that ...

I can see from the image you are not providing a clock signal and do not have a crystal or resonator connected to the target.

But same problem still.

Re: ATMega328 (Non P) and 'Upload Using Programmer' error

Posted: 20 Dec 2012 11:59 PM PST

Using an Arduino Uno, you can program your Atmega328 with a bootloader or directly with any other hex file (you do not really need a bootloader for most applications) by following the steps of this tutorial: http://pdp11.byethost12.com/AVR/ArduinoAsPro...
