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 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
