FEZ Cerb40 II - PWM's = 11?

Just a question, I see 1 PWM on the Datasheet but currently PWM = 11 in the Specs. Which one is correct?

See: https://www.ghielectronics.com/catalog/product/450

if it is 11 thats pretty impressive for such a small board!

After looking at schematic ( http://www.ghielectronics.com/downloads/schematic/FEZ_Cerb40_II_SCH.pdf ) and the Developers’ Guide ( https://www.ghielectronics.com/docs/47/fez-cerberus-developer#420 ) , I couldn’t find 11. So, I asked one of the hardware engineers. He said 11 !!

cursory examination of schematic and sketch from engineer shows these are missing:

PWM_14 PB8
PWM_15 PB9
PWM_10 PB10
PWM_9 PB11

Hi Jeff,

Sorry, Datasheet was the wrong word, I meant the Schematic: http://www.ghielectronics.com/downloads/schematic/FEZ_Cerb40_II_SCH.pdf

A fresh look this morning, I can see a few more, now I see three:

PB3, 4 and 5 are PWM, JP 20, JP 11 and JP 9, are the Pin Out PWM’s

Cpu.PWMChannel only supports 8 PWM’s

new PWM(Cpu.PWMChannel.PWM_0...
new PWM(Cpu.PWMChannel.PWM_7...

If there is 11, how does one access the extra 3 Pins?

I guess a cast?

(Cpu.PWMChannel)Cpu.Pin.PWM_14 PB8

Thanks for your investigations!

All the best


be nice to capture all these idiosyncratic items somewhere ::slight_smile: like the developers guide… uart to COMx and pin mapping
