PWM channels for LPC43xx

[lpcware]

I am evaluating LPC43xx for my application. I need at least 6 PWM channels on it. NXP parametric search (http://www.nxp.com/parametrics/71562/) states that there is only one PWM channel (for motor control). But SCT also generates PWM, right? (as described on http://ics.nxp.com/support/microcontrollers/sct/).
So, I would like to know how many PWM channels I can configure on SCT. All the 16 outputs?
By the way, it is configurable, right? So I don't have to program interruptions on the microcontroller to check/change pin state.

Thanks in advance for any support.

We suggest that you use the Red State tool within LPCXpresso.
If you prefer not to use LPCXpresso, then you can use the Fizzim tool.  This tool can be found at <a href="http://www.lpcware.com/content/nxpfile/sct-tools">http://www.lpcware.com/content/nxpfile/sct-tools</a>.

I tried to find the SCT-Tools on Lpcware.com, but I could not find them. Can anybody help me getting them?

Thank you very much, Bavarian. That really answered my question.

Best regards,

Yes, the SCT can do PWM. There is an example attached. The SCT-Tools are available on lpcware.com, containing also other examples (which maybe do not perfectly fit to the latest hardware with regards to pin assignments).

In principle you could do PWM on all available outputs. Please check the documentation from the example.

Once configured the SCT runs without any processor interaction. So there is NO jitter.
