Hello I?m working on 21065L EZ-LAb, and I try to connect AD7865 (ADC) via EMAFE connector. I want to set up DMA to get sample, I connect DMAR1 on EOC signal from ADC. I configure my DMA register (DMAC0)=0xE01; paced master mode and I enable EPOI ISR . I want ISR at first

I am designing with the ADSP-21065L but the 3 ns rise and fall times requirements for the CLKIN seem very hard to obtain from vendors. Digi- Key, Newark and some others only sell clock oscillators with longer rise and fall time. I suppose that those requirements are not necessary if I use instead a cristal with capacitors and let the DSP to

hi has anybody already attached the Eval-Ad73360eb Board to adsp-21065L? Does somebody by chance have this Board "Eval-Ad73360EB" and would it like to sell? If also one has built this Board before, I also would be very pleased if he helps me! Analog devic

Hi all, I'm trying to implement a glueless RS232 interface to SPORT0 on my=20 21065L. My code is based on the ee-191 engineer to engineer=20 note, "Implementing a Glueless UART Using The SHARC=AE DSP SPORTs ". = =20 I've tied the RFS0 and DR0A pins together. The problem is that the=20 SPORT will occasionally lock up while receiving data from a PC over=20 the RS232 interface. I have t...

Hi, For a project I'm working on, I need SDRAM interfacing to the ADSP-21065L (my very first project involving design with SDRAM parts). One suitable part is the MT48LC2M32B2 from Micron. Has anyone already used this part or any other very similar for interfacing

Good morning, I am developping on an EZ_KIT 21065L evaluation board and I have some trouble with SDRAM init. When I load the program with ICE Emulator or serial port, it works but few values in function table in SDRAM are wrong. When I load in flash EPROM, It doesn't wor

Hi all My code requires transfer of data from the adc to the ext.mem of 21065l using dma and external port.I know that I use the external handshake mode. So the source is my ADC and dest is the ext.mem.so of the parameter registers i use the external ones to index the add

Please refer to the chapter-10 of ADSP-21065L User Manual. The minimum size supported for SDRAM is 16 MBytes. If you use any size less than 16 MBytes (as you seem to be currently asking), you will not be able to use some of the address ranges of SDRAM - because these address ranges will be aliased to some other address ranges. For example with 8MByte SDRAM (as you are asking), (1) remaining ...

I have a strange problem occurring. I have a 21065L that does DMA through the sports audio in/ audio out, on interrupt. When buffer gets full, sport interrupts, I swap dma buffers for outgoing and ingoing, to a second outgoing and ingoing buffer, so that I can process the full data buffers. All works fine, except once in a while, failure is not peri

Hi! I'm planning to use a flash drive for memory expansion of ADSP-21065L. To interface this (flash drive) to the DSP board, I will use a USB female port to 9 pin female serial port connector. The 9 pin female serial port is to be connected to the EMAFE of the DSP board and the USB female port to the flash drive. How can I connect the USB port to the serial port? Will that be a simple ...
