Analog Devices DSPsHi, I'm in the same position: I work for a small company with an open-source mentality that balks at paying thousands of bucks for the VisualDSP toolset. So when we wanted to make a product with a DSP, I chose the ADSP-2181, used the old command-line assembler that came with the EZ-KIT, and made my own debugger that connected through the DSP's IDMA port. The 2181 is a pret...

Hi, I'm currently working upon a project that requires displaying graphics upon a LCD panel. I wish to do this using the ADSP-BF537, AV Extender Board and ITU656 protocol. I'm relatively new to this area, therefore I was wondering if anybody has any relevant example C code to display simple graphics using the above hardware. Regards, dob84

Hello everybody, I have an important question for you. does anybody know about the 90-pins connectors of the 21364 EZ-KIT LITE board. I need to use the PWM, SPORT and SPI but i didn't find any document about them. I hope they are accessible.

We are starting to use an ADSP 21161N Ez-Kit lite board but we have problems with the execution of the first code examples. We arrive to simulate them correctly but once they are loaded in the target we notice that program counter is increased in a strange way (sometimes it jumps more than one position without an explanation) so some instructions are not executed. What may cause this...

Do these two work together? Background: Needless to say I have a *very* urgent job. I need to provide a DSP solution for high end active speaker equalisation. I have little experience of DSPs, and none concerning this processor or board. I need a very low noise 24/96 ADC/DAC with stereo in and at least one stereo out (although more is better). Ideally I'd like 4 stereo in and 4 stereo out...

Hi all I am just starting to learn about the sharc family of ADSP-..., previously I have only been using ADSP-218x processors so please bear with me if this question is trivial to experienced sharc users. Due to an expected memory constraint in the project I have just been assigned to which will be using the ADSP-21375, we want to split out some of the software to different builds which mu...

Hi guys Can anyone suggest a way to have the TS101 run a script without needing the VisualDSP++ program. I plan to use the Visual DSP++ to initally load the code onto the DSP but then want the dsp to run this code without needing to be attachted to the PC. Any suggestions? is this doable with our development kits? regards kien hou

Dear All, I would like to know how to allocate vaiables to a particular segment in PM or DM when the code is written in C and cross-compiled using g21k (EZ-LAB Development System, SHARC ADSP 2106X, 1996 edition). To ellborate, if X, Y, Z are three global variable, I would like to allocate X in DM Seg1; Y in PM Seg 2, and Z in DM seg 3. regards SS

Hi guys Need some help, from what i have been reading the ADSP_TS101 A-D converter (AD1871) samples each input channel at 48KHz. I only need it to sample at 8KHz. I can't seem to find any documentation as to how to reduce the sampling rate. Otherwise ill have to put a hack together where i only store every 6th sample. Can anyone help me with this? regards Kien
