PWM - first cycle after reset
MCU: ATtiny2313 I use a hardware PWM pin to control the enable pin of a LED driver (constant current shift register). It works as expected, only that after reset all of the LEDs...

[solved] brown-out module running berserk ?
I'm using an ATtiny24 (8MHz, internal RC oscillator, 5V) to control a LED driver, essentially an 8-bit shift register with internal current control. Total current is about 1.5A. I...

optimization -Os vs -O3 effect on: _delay_ms and ISR timings
I'm using an ATtiny2313 to drive a constant current sink led driver (essentially an 8bit shift register) using the USI-SPI hardware. In principal everything works as expected, but...

16bit registers again :-(
I've read the datasheet and the appnote about accessing 16bit registers in assembler. Byte order and so on, but I use avr-gcc so the compiler should know how to deal with it right...
