Independant control of both PSC pins w/ >100% duty cycle
Never used one of these but from reading a few pages and this PWM waveform generation function (2 complementary programmable outputs) • Dead time control i would think the...

stepper motor control
You must also control the timing of the steps. A sub routine that performs a loop to step a motor more than 1 step that also incorporates time delays can be very poor code if your...

AVR loads, executes code, resets and executes code again?
Is this connected to the serial port on a PC? Perhaps voltage on serial line not level shifted? Try disconnecting serial connections and run AVR see if it resets or times out and...

How to read I2C buffer
How many iterations will you get when you send a zero? Depending on the number of bits in the variable and your drawbusy code it could be 65,535 iterations before it gets back to...

Atmega8 USART problem with interrupt
Perhaps it is the UDRE flag. When you fetch the byte and store it in the next cycle the UDRE flag may not be set and the USART ignores the byte to be sent. That is a guess don't...

interrupt driven USART_UDRE buffer problem - atmega48
You posted it works when you insert a delay in the LCD_WData() function. Is this correct? Could you post the LCD_WData() functions code? I still think it is the call from inside...

interrupt driven USART_UDRE buffer problem - atmega48
I will toss in a guess here. calling functions from inside an ISR can be tricky. I would try writing the called functions inline and see if that helps. Declaring outside functions...

Brain exercise project, watts, temperature hotplate
I will email him Jim's concern, like I said FR4 and this board would not be a choice i would make. Initially i thought 120F is all he needed but your testing shows that is even...

LM35 and ADC ATmega128 interfacing , Help urgently
I was not referring to the interrupt flag. What I mean by setting a flag is creating a global variable that the interrupt sets when triggered so your main program can poll to see...

Brain exercise project, watts, temperature hotplate
Thanks for the replies. The Ultra-Thin Polyimide Heat Film looks like a very nice option to mount under a piece of aluminum. I also see some very nice silicone square heat pads at...
