Hi all, I got the transmit and receive portions to work with help from a couple of newsgroup replies. My project is for a custom board, with different dai pins from the eval board, and it's a vdk project using the ADSP21262, so it won't just be a drop in for you. It might be help anyway so I'm sending it along. I'm not sending the complete project, just the parts about the UART. Let me know if you have trouble, I'll try to help.

I have tried to modify the EE-191 'glueless software uart' code for my processor but havent been able to get anything to work. Has anyone successfully ported code from EE-191 to an adsp processor other than the 21161? Many thanks Ronan O'Malley ________________________________________________________________________ ________________________________________________________________________ Message: 3 Date: 3 Mar 2006 21:09:57 -0000 From: "shwetha Belame" <jshwetha@jshw...> Subject: ADS8344 and BF533 � Hi, I want to interface the A/D(ADS833) from TI with BF533. This A/D has a serial interface. I have following question in the SPORT chapter they tell that....... 1) "The data received on the primary and secondary pins is interleaved in main memory" in this sentence does the main memory mean the on chip SDRAM (L1 data memory)? (I am not planning to have any external memory on my board.) 2) "For receive, the data bits (DRxPRI and DRxSEC) are synchronous to the receive clock (RSCLKx). The serial clock is an output if the processor generates it, or an input if the clock is externally generated. Frame synchronization signals RFSx is used to indicate the start of a serial data word or stream of serial words." This A/D ( ADS8344, from TI) has a pin (DCLK) which is a serial/conversion clk. and the clock speed determines the conversion rate given by Fclk =24*Fsample so I was woundering to which pin of SPORT this should be connected is it the RSCLKx or DRxPRI. and what has to be done to the other that is not connected? and another pin ( Din) a serial data pin thor' which you have to tell every time from which of the 8 i/p channels the sample should be converted. I don't know as to where this pin has to be connected on BF533?? 3) In my application this is the only device that is interfaced with the BF533 and has to selected from the time the board is powered on..so the CS/ ( chip select , pin that is active low) can that be held low all always? how do I do that? I hope to hear from you all at the earliest Thanks in advance, Sincerely, shwetha ________________________________________________________________________ ________________________________________________________________________ Message: 4 Date: Sat, 4 Mar 2006 14:12:05 +0100 (CET) From: Giovanni Parodi <giovanniparodi79@giov...> Subject: LED Blinking Hello everybody, I bought a used BF533 EZ-KIT LITE board and I would ike to use it. However when I connect it to the PC the LED start blinking in a circular way and the board is not recognized by the Visual DSP++ installation. I think this is a flash memory problem. So I would like if there is someone that can provide me an help solving this problem. I have the JTAG emulator, so I can try to program the flash but I need a fresh "image". Thanks a lot Giovanni ___________________________________ Yahoo!

Hi all, I'll have to connect (USB) a Linux box with a Sharc-board (dspstak 21369), which is very much like the 21369 EZ board with Sharc USB Extender (NET2272 chip). (I know that VDSP++ provides a couple of files for Windows ) Did anyone do this with Linux before? Or is anybody currently working on this? Probably this is just a generic NET2272 driver, which would lead to a common Linux task then (and I had better ask elsewhere). Nevertheless, there might be special issues and somebody knows...
