Hello,

I beleive this is what you're after.
I'll get them put on the website for you.

Hello,

Please can you post your latest project file and I'll do what I can to try and replicate the issue.

Hello, The CAL component should work too but you have to call the SetPeriod macro to setup the clock prior to enabling the channel. This is the same for most MCU families. The top level PWM output component uses the CAL component but simply does the SetPeriod call for you inside the Enable function.

Hello,

The LK4221-2 and the LK4690L are now both discontinued and I don’t believe they have a direct replacement.

The LK1800 is almost a separate and different kit … but the LK1800 is available.

Hello,

Excellent sounds like we're making good progress.

The frequency can be whatever you like but the duty can only go from 0 to 16383.

This program uses IO pin 8 as the LED and PWM output pin.

Hello,

The Dfplayer module is fairly low cost and supported by flowcode. Uncompressed mp3 on the fly in a micro is a fairly processor heavy task.

Hello,

This is a good place to start with the firmware download.

I'll ask about the solution for you.

Hello, Right hopefully this is now resolved for you with the latest library updates. I've confirmed it's working, I managed to find a C3 in my pile of ESP32 bits. Please note the maximum period overflow for the C3 devices seems to be 16383 (14-bit) rather then the usual 65535 (16-bit). Now to invest...

It looks like the C3 has a different PWM module to all the other ESP32 devices named LEDC.

I'll see if we can support this alternative module in the CAL code.

Hello,

I've just tried the C6 supermini and this is working fine with PWM. I don't currently have any C3 hardware so I'll get some on order but in the mean time i'll also look into the compile issue for you.
