Hi everyone I'am using the motorola DSP56807evm and the SDk 2.5 Libraries, I want to know if someone knows a way to works 8 gpio pins in parallel in order to read a byte from it. My problem it`s that the SDK only works the gpio pin by pin. Thanx for your patience

Hi, I want to use two GPIO pin as interrupt in my application. Since I didn't found any information on how to do it with the SDK, I must write and find a way to call an ISR on a pin change. For now, I know how to set the GPIO registers and write my ISR. But I don't how

Hi... Multiple Interrupts in GPIO -I can configurate most than one GPIO Pin to generate a Interruption, All those pins had the interrupt vector of 23! To know which pin make the Interruption I must read the register IPR (Interrupt Pending Register). But I?m using

I would like to input a clock signal into a gpio pin on the dsp56f827 which has been generated from timer_A2. (Timer A2 physically wired to the GPIO pin) I then want to compare the clock signal input to the GPIO, to a clock signal on timer_A3. If the signals have

Hi everyone, There is a bug (hopefully not one in many!!) in SDK2.4. (I am using the 56f807evm) When using the GPIO Api's, it does not want to work if gpio.h or io.h is included. It will only work when led.h is included. Also, when I include switch.h, the compiler give a strin

Hi, I am trying to use the GPIO interrupt mechanism but I have a problem: Immediately after I enable the pin interrupt - the interrupt occurs. It happens every time I try it, no matter what the polarity is or any other parameters I configured (I think I tried them all).

Hi code wizards (or warriors), I still haven't got my GPIO interrupt sorted using the 56F805EVM board and CW. I use the code below but I must miss something as it is not doing what I expect. I expect it to end up in the routine dirISR but it never gets there. I have tried using the s

Does anyone know the official channel for SDK feature enhancment? I added the following macro to help with initalization of my gpio port a port at a time... Its a variant of the gpioPin macro it would might be a reasonable addition to the SDK. #define gpioPort(Port) (((

Hi all, using a 56F805 I want to use the level sensitive interrupt input on a GPIO line. While I find all sorts of high level routines to set various operation parameters I don't know how to set the interrupt callback function. How can I set this callback function? Do I have to

The evaluation board has RTS connected to CTS. I am using an MSComm ActiveX control to talk to EVM. All is well. The production item will use SCI0, with RTS and CTS represented at GPIO D. I am at a loss for how to emulate this loop-back in software! Thanks
