You need to make sure that the priority level for the interrupt is greater than zero. This by defining the priority level in the appconfig.h file. An example is below:

#define GPR_INT_PRIORITY_42 2

Just as an FYI you can also statically install your ISR by using the defines such as given below:

#define NORMAL_ISR_8 UserIsrLabel

Section 7 of the SDK programmmer's guide has a good description of using the different interrupt levels support and installation. But in regards to the dynamic installation this is useful if the ISR service routine needs to change during the run time operation. If the ISR never really changes then the static installation is good and saves some space. Thanks.

Subject: [motoroladsp] GPIO interrupt callback?

Hi Istarted using the SDK enviroment 2 weeks ago before that I used Radagast but since I could not get a sine function going and SDK had one already I started coding in SDK. I also tryed doing the GPIO interrupt. According to the registers of the flash everything is correct. The archInstallISR is getting the the right adress 0x0FC8 which will be for Port B. Iam trying to get a interrupt on pin 4. gpioPortB = open(BSP_DEVICE_NAME_GPIO_B, NULL); archInstallISR(&(pArchInterrupts->MpioB), dirISR); ioctl(gpioPortB, GPIO_SETAS_GPIO, gpioPin(B,4)); ioctl(gpioPortB, GPIO_SETAS_INPUT, gpioPin(B,4)); ioctl(gpioPortB, GPIO_INTERRUPT_ENABLE, gpioPin(B,4)); But I am also getting the same as Manfred. I also tryed getting the proirity high but still iet will not interrupt. This was done on the DSP805EVM with the SDK. If somebody can help it would be great.

Hi I am using the DSP805. I only set that pin of GPIO port b pin 4. The problem is that it does not go to the ISR. I included the clearining of the interrupt in the roteen and the reset in the setup. But still it does not go to the interrupt roteen. Regards. Frikkie. -----Original Message----- From: Nitin Madhukar Yewale [mailto:] Sent: 23 January 2003 17:38 To: ; Subject: RE: [motoroladsp] GPIO interrupt callback?

Hi, Are u using codewarrior for development? If so then u can assign GPIO ISR by using following function call archInstallISR(&(pArchInterrupts -> GPIO_Port), ISRRoutine); Regards, Nitin -----Original Message----- From: drmapl <> [mailto:] Sent: Monday, January 20, 2003 7:26 AM To: Subject: [motoroladsp] GPIO interrupt callback? 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 put a JSR statement into the interrupt table by hand?
