Technical discussions about Freescale (Motorola) DSPs (including the DSP56000, DSP56300, DSP56600, 56800 DSPs).

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 string of errors which are mostly in the header file! (Bug no.2). If my findings is incorrect, please let me know and also why it is like this. Also be ware that when you use the user leds, that GPIOB0 -> GPIOB2 will be unavailable as inputs because the leds use them. Regards Roelof Oelofsen Telkom Development Laboratory Telkom SA |

Roelof I have not tried using the GPIO Api's without led.h since I use the LED functions. It is true that the user leds are set to port b pins, but since you have the source code you can modify what pins are used. I beleive somewhere in Motorolas documentation they mention that the SDK is a starting point and that they assume the user will eventually modify/cusomize the functions. Just another note in the SPI handler, the provided SDK functions always set up a GPIO pin for the chip select, even if you are using your own select functions. You need to modify the code so it will only setup the pin if you use the default chip select -----Original Message----- From: Roelof Oelofsen [mailto:] Sent: Wednesday, May 22, 2002 7:04 AM To: Subject: [motoroladsp] Bug in SDK 2.4 Hi everyone, There is a bug (hopefully not one in many!!) in SDK2.4.
