Pins of port matching bits of a variable. Not rly XOR ques.
Hi everyone, Im curious if its possible to take the complement of a single bit or multiple bits. I am making a fixed frequency signal on two pins (50 duty cycle), each one the...

Trouble connecting ATtiny88, but not ATmega644 (STK500)
Hello, I am using an STK500 and have an ATtiny88 on it. I cannot manage to connect to it. If I replace it with my ATmega644, when I press read signature, it reads it, when I go...

ADC conversion time
Confusion strikes: ATmega644 Datasheet: Statement 1) ADC Features: 65-260 uS conversion time Statement 2) ADC conversion time (from table), normal single ended = 13 clock cycles (...

Is it safe to assume...
Is it safe to assume that if a general AVR has: 1) TCCR0B, then the prescaler bits are located in bits 2:0? 2) no TCCR0B, that the prescaler bits are located in bits 2:0 of TCCR0A...

My chip won't program its EEPROM anymore?
Hello everyone, A long time ago I made a servo controller with an ATmega168. It was cool and awesome and all that good stuff with configurable user data via recording values in...

AVR Simulator / Sumulator 2???
Hi, I have never used the simulator, always using UART to debug my code. However, I have finally found a need for it, and from what I can tell, it sucks! If I try to set my port...

STK500 to breadboard hlp! Could rly use another set of eyes!
Hello everyone, I have a program that works perfect on the STK500, so I through it on a bread board. I have feedback when I sent it UART commands. With this configuration, pretty...

[solved] BOD interrupt?
I have an application in which I have enabled brown out detection to prevent garbage from coming in through the UART pins. If I remove power and apply it again quickly the circuit...

[solved] Circuit resets upon plug in! (hardware problem)
Attached are a circuit diagram and a circuit picture. It's an ATmega168 8-servo controller with 1us resolution. I'm sure you all know the theory. And yes, I know I don't have...

Servo just won't work!
Ive checked with a frequency meter, I'm getting 50 Hz. I have high resolution in Phase Correct PWM mode (ICR1 = 20000). 16Mhz, no CKDIV8. Frequency is supposed to be f =...

Master/Slave SPI... Oh boy
Ok I really don't to have to post ALL my code, so I'll see what I can cut out. The problem is I am sending a character with an ATmega8 to an ATmega644. ATmega8 = master, ATmega644...
