PWM base frequency (by Ziggy)
Hello Room,
Been a while since I last looked at LDMicro. Since then a whole bunch of changes took place. I was wondering whether LDmicro has the capability to output a tone not unlike arduio tone() function or potentially output a PWM signal at a programmable base frequency? say 2.7KHz and 50% duty cycle.

Available several fixed values of PWM base frequency , depending on the frequency of the processor Fclk and selected prescaler.

LDmicro gets your target frequency,
calculates the prescaler, then calculate the fact PWM frequency, and if target and fact differ more 5% send Message. So with 16MHz oscillator you can select 65.2k, 7.8k, 976, 244 or 61 Hz PWM frequency only.

Other way of PWM described in
"AVR136 Application Note" You can sponsor developing it. Contact to [email protected]
