Bug in ARM PWM Component Macro

[ARM]

Hello,

After I had plug in a PWM component in my system I got the following compiler error:
(The error occurs also when I open an empty project and add a PWM component to the System window, without any PWM program code.)

Hello Arm,

Thanks for letting us know.

Please find attached an updated CAL file below. The file needs to be placed into your "Flowcode 6/CAL/ARM" directory and then hopefully the compilation will be ok when using PWM components.

Let me know how you get on and I will check in the change.

Hello,

I have replace the CAL file in the ARM directory and now the compiler generats the folowing message:

Aha,

Sorry about that. Have you got the latest PWM component files from here.

Hello,

I had copy the update files and now I have no compiler error. There are still warnings (see attachment), but
the program runs. Many thanks.

I have still two questions to PWM component:

1.) In the properties of the PWM component the maximum value of "Period Overflow" is 255.
The maximun value of "Prescaler" is 1024. So the lowest frequency where I can generate is 0,1828212 KHz (PLL Frequency 47923200Hz and 18,432MHz XTAL).
It is not possible to set the "Period Overflow" to value 65535.

I need this to drive the stepper motor very slow (about 2 Step per seconds) manually via encoder hand wheel.
Is there a way to generate a frequency over PWM channel with 1Hz.


2.) When I open component macro "PWM" "Change Period" I cannot change values. The PWM frequency in the running program is
always the same as the value in the PWM properties. I had "Disable" PWM then "Change Period" and then "Enable" PWM,
but it also doesn´t work.

Hello,

here I have the latest update:

In PWM component:
()=10bit command
Cannot set duty cycle. 0-1 (0-19)=PWM is off. 2-255 (20-1024)=PWM is running but no frequency change. Testted with "setDutyCycle" and "SetDutyCycle10".
And command "changePeriod" has no effect. Only value in the PWM component Properties is active.

(Tested with a simple stepper motor driver)
