Hello all, the 65L has two serial ports, 0 and 1. Each serial port consist of two seperate data lines, A and B, making a total of four serial I/O lines. I seem to remember that when a serial port was operated in multichannel mode, it could not operate both A and B

I'm using a 21065L and am trying to find the quickest way to split an interleaved integer array into two float arrays. Details : My input array consists of 128 samples of codec data as i1,i0,i1,i0,i1,i0,i1,i0... I need to convert this into two separate float array

I'm interfacing a cluster of ADSP-21065s 32-bit host port interfaces to a member of the Mot Coldfire and have been around and around about how to connect the address lines of the Coldfire to the address bus of the 20165L. I think we should start the address bus connection from A2 on

Hi! I'm new with VB and VisualDSP++. I am doing a GUI that should be able to access the ADSP 21065L's memory but I encountered lots of problems doing it. The major one is this: I used the ExecuteTcl() command passing just the basic TCL command "DSPrun" as parameter. The exact code is: Option Explicit Dim result as Variant Private Sub cmdRun_Click() exe = ExecuteTcl("dsprun", ...

Hi, I am accessing a 21065L via the host port and want to download a program. I wrote my own boot loader (because of several problems) that sets up SYSCON, enables global interrupt, enables interrupt IRQ1, disables the interrupt of the DMA1 (EP1I, the DMA channel I use to down

Hai everyone, I am a Final year student in BEng(Hons) in digital communication and Electronic, I planned to design bluetooth module with SHARC DSP (i am trying with ADSP- 21065L ?) interface for full duplex advanced wireless audio application, please would you please let me know what SHARC DSP is most suitable for my development. How can i configure with bluetooth module effectively. I...

Is it a bug of the ADSP21065 serial port? To process data of the ADC AD7671 I have connected its SDOUT, SCLK, and SYNC pins to DR0A, RCLK0, and RFS0 pins of the ADSP21065L according to recommendation of the AD7671 Data Sheet. But 16-bits date words entered into DSP via SPORT0 l

The latest 65L anomaly list and PROM loader source code show the need to set A23 for BSO accesses to get the correct number of wait states. I believe this explanation is incomplete at best, and the real reason A23 is needed is that CPU 2 will misinterpret CPU 1 PROM accesses as MMS a

Hi, I have a situation where I want to generate a file in loader format, BUT, without a loader, and only includes the program code in loader format (e.g. tagged so a boot loader type code can decode it and put it into its respective memory type and location)

I'm running a regular IIR biquad program copied from adi on the board but it isn't working. At start it emits a beep then nothing--I can't hear my input voice. When I press the flag for talkthru I can hear my voice. My delay line became filled with FFFFFFs (overflow?) when I halted t
