A few possibilities I see:
1. Port configuration may not be correct.
2. The compiler disables global interrupt in timer ISR entry. Hence while you are sleeping in ISR, interrupt not forwarded to software.
I am wondering, why Class AB is used in voltage amplification stage and Class A in power amplification stage? We do the opposite at audio frequencies..
The best way will be to provide a clean DC to the motor input. The closest you can practically get, in my opinion, is to use the PWM to control a Buck Converter. The DC motor can be used as the capacitor of the buck circuit.
Thanks Jack.
Xaacto, from the discussion and a few readings, what i think, is that, if you don't suspect a high probability of radiation induced errors or any other kind of prominent cause of faults, you can design with consumer grade electronics.
No matter what grade of component you use, you...
Thank you keith. But I'm not involved with any medical project at present.
Due to the recent happenings in the automotive sector, every embedded engineer has got some interest towards reliable designs. Everywhere people speak of hardware reliability first. But from my experience, it was not so...
Re: Hardware Reliability
Thank you keith.
That means the life critical equipments are designed with redundant modules.
No matter what the component or module reliability is, we will go for such designs to reduce the chance of damage to life. But what about the actual digital component failure...
Hardware Reliability
You might have noticed a disclaimer in the end of digital IC datasheets(eg. 74ls series), that they are not guaranteed enough for medical uses.
I have no experience with a digital IC failing (unless mishandled). Nor have i worked in any digital manufacturing companies.
So...
Re: Pausing a C program?
Pausing requires some other process to execute or somehow to halt the system. The former is OS dependent. So some system calls, as i see in Linux now, is required for such jobs.
Download through serial port to 8051 and use a parallel DAC. The available sample rate and resolution will only be sufficient for speech(Limited by serial port baud rate).
McBSP channels
Why McBSP(Multi-channel Buffered Serial Port) is called "Multi-channel"?
1.Can it be used to communicate with multiple peripherals simultaneously?
2.What if the peripherals use different protocols?
