Hallo Cassiopeia,

> und nen timer 2 hat der mega32 net oder?

das Datenblatt zum verwendeten µC ist häufig eine unerschöpfliche Quelle an Information!

Auszug aus dem M32 Datenblatt der Firma Atmel:

8-bit Timer/Counter2 with PWM and Asynchronous Operation

Timer/Counter2 is a general purpose, single compare unit, 8-bit Timer/Counter module.

The main features are:
• Single Compare unit Counter
• Clear Timer on Compare Match (Auto Reload)
• Glitch-free, Phase Correct Pulse Width Modulator (PWM)
• Frequency Generator
• 10-bit Clock Prescaler
• Overflow and Compare Match Interrupt Sources (TOV2 and OCF2)
• Allows clocking from External 32 kHz Watch Crystal Independent of the I/O Clock

Overview
A simplified block diagram of the 8-bit Timer/Counter is shown in Figure 53. For the actual placement of I/O pins, refer to “Pinout ATmega32” on page 2. CPU accessible I/O Registers, including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit locations are listed in the “8-bit Timer/Counter Register Description” on page 123.

Ciao,
Werner
