MAX232 and USART issues.
I have the recommended capacitors on the regulator, I didn't originally and thought that was the problem. I've used multiple wall warts, but my last plan of action is to bring my...

New tools released: AVaRICE-2.5, AVRDUDE-5.2, avr-libc-1.4.5
Is there a win32 release of AVRDUDE? The most recent I can find is v5.0.

[TUT] [C] GCC and the PROGMEM Attribute
Yeah, it was the .pdf. I was looking at that since it's nicer to look at than the forums. Sorry, I should have specified more clearly. That said I'm still seeing the error in the...

[TUT] [C] GCC and the PROGMEM Attribute
I recently dealt with the same error as rotamat brought up with USART_TxString_P(). pgm_read_byte() takes a pointer, which is pointed out in your explanation (that's how I figured...

MAX232 and USART issues.
I'm using a 7805 Linear regulator, rated at 1.5amp I beleive. Going into this is a 9v wallwart rated at 700mA. I'm seeing 4.9v at the regulator/micro/max232.

Setting up an RS232 Connection with the mega48
I've been writing a GUI to control my AVR project using MATLAB. They have a very easy to use and learn GUI interface, meaning that it is extremely well documented by the authors...

MAX232 and USART issues.
I've got them properly connected as in pin 5 of the serial cable is commonly grounded to the micro/circuit ground. It's a mystery, huh? I will appreciate any other suggestions.

Three feet probably, it looks like your standard serial cable. I don't think it's the cable itself because I don't put the bypass capacitor on the transmission line on the PC side...
