Hi, I am trying to program an ISR in MSCAN recieve routine. I went thru the archives and found a message frm Art Johnson which was regding the usage of #pragma Interrupt. It will be gr8 if someone culd send me the J1939_task.c file to refer to ISR programming. I am attachin the message frm Art BELOW... Thanks, Chandru RE: si

Hi, everyone!. First of all I've gotta say that this is my first post in this interesting Motorola DSP Group, so I hope you will understand and forgive me whether I'm asking a big nonsense. My problem is the following: I am trying to implement a SPI communication between a DSP 56F807 and a ColdFire MFC5272, configured as slave and master respe

Hi, I am using the DSP56374 and I am testing the current consumption in STOP Mode. The datasheet says that in STOP mode the DSP should not consume more than about 2 mA. (core: about 1.2mA; I/O current: about 1.2uA) I have a current consumption of about 11 mA (core + I/O). The core current consumption seams to be great (i have about 1.3 mA) But th

How good is Processor Expert for the DSP56800 Family. I am starting a new project using the DSP56858 and would like to shorten my software effort. Is PE a useful time saver that eases the effort or a burden.

anyone know how to get metrowerks to print out C and asm as well as asm line numbers? I'm trying to go from P:12DC A001 BCC 0x12DE to the equivelant in my C code. I remember doing it with my 68000 so I'm hopping I can do it here. thanks, tom

I am trying to use either MAC or MPY to make a product of two variables. The problem I have is that the result is always of twice of the expected. For example, If I multiply 1 by 1, the the result I got is always 2 other than 1. The following is the code I used; The C portion: int multiply(int, int); int some_global = 4;

On DSP56F807, I found a condition on which occasional code restart happens. The code in execution when the code restarting occurs is the following (C code and relative disassembly): // CAN Rx interrupt disabled during queue counter manipulation. periphBitClear(CANRXFIE, &ArchIO.CAN.RxIntEnableReg); P:00003471: 80F411850001 bfclr #0x1,X:0x1
