Re: Pauls personal autopilot project board....

Nope no launch this weekend...
On Friday night I connected a battery backwards and cooked my guidance servos....
(My electronics survived just fine.. the servos let out the magic smoke...)
I now have spares and the next launch is on Feb -2.

Re: Pin class and IRQs on 54415 parts

Look in the platform include directory for intcdefs.h I'd use thoose macros on this platform.

Re: Pauls personal autopilot project board....

I Don't know how much.... Depends on if I'm selling a few of the 10 I built or if we decide to produce somethign like this... My cost to produce the 10 prototypes was about $125 each with zero pprofit... As far as using in a HPR, I'll let you know on Monday this is flying in a 3 motor gimballed rock...

Re: Multiple calls of OSSemInit()

putchar is standard I/O just like all the other I/O. Disregard my ISR level questions if you are not using external IRQ pins.... Calling ANY I/O that calls RTOS functions from inside an ISR can break things... so remove the putchar and add the interrupt counters and see what happens... What platform...

Re: Multiple calls of OSSemInit()

Several problems here: 1)First you can not do io like putchar from an interrupt... Hunt down the programmers manual section on interrupts it tells what functions are and are not ok... 2)The external interrupts have to be at their native priority... IE IRQ3 has to be 3. The register interface looks l...

Re: Multiple calls of OSSemInit()

If no tasks are pending on the semaphore, it does no harm.

However from a code maintenance standpoint I see it as a bad idea, because in the future you may never be sure
no tasks are pending..

Re: MOD54415 ADC and DAC

If you look at the ADC driver...
and the freescale manual, you should be able to not enable the two DAC channes in the example A/D code.
This should do what you want....

Re: Multiple SBL2E's on one network - DHCP issue

To be 100% DHCP compliant one is supposed to add a random boot time delay of 0 to 10 seconds to the DHCP discover message... When we did this people complained about the long boot delay... When we ported to the SBL2E we did not include this delay... It would be pretty easy to add..... I would expect...
