And I'm currently running a passthrough application<BR />debugging is done via Parallel port.<BR /><BR />I now want to implement the a 10BandEquilizer like in document DSP56311_Implementing10BandsEqualizer.pdf<BR /><BR />Problem is to change settings.<BR />Is it possible to control the application via RS232 ?<BR />RS232 is connected via the DEBUG MPU to SHI of the DSP. But I canot change the code of the MPU.<BR /><BR />Another question: is the 56371 allready supported by codewarrior? And does it bring a contribution?<BR /><BR />Thanks in advance<BR /><DIV></DIV></BODY></HTML> Tue, 24 Jul 2007 20:39:03 GMT https://community.nxp.com/t5/Other-NXP-Products/DSPAUDIOEVM-with-DSP56371-How-to-control-via-RS232/m-p/141006#M253 rvdv2001 2007-07-24T20:39:03Z Re: DSPAUDIOEVM with DSP56371 How to control via RS232 https://community.nxp.com/t5/Other-NXP-Products/DSPAUDIOEVM-with-DSP56371-How-to-control-via-RS232/m-p/141007#M254 <HTML><HEAD></HEAD><BODY>The RS232 port on the DSPAUDIOEVMMB1 is connected to a microcontroller, not directly to the DSP.&nbsp; It serves as an asynchronous to synchronous serial translation device for use with the Symphony Debugger (SDI).&nbsp; The communication protocol has not been made public, since the protocol is largely connected to the internal operating system in the ROM.&nbsp; The best bet to achieve serial communication between a host PC and the DSP is to use a USB or RS232 to SPI or I2C adapter, connecting that directly to the SHI port on the 56371.<BR /><BR />There is no CodeWarrior support for the 563xx family of 24-bit DSPs.&nbsp; The only tool suite currently available is Suite56.&nbsp; There is a new tool suite based on Eclipse that is coming out later this year.&nbsp; It offers USB debugging support in addition to the legacy parallel port.&nbsp; A port of the GNU C compiler is included with eventual support for Altium's C compiler.<BR /><BR />As a side note, to port the 56311EVM graphic equalizer code to the 56731, you need to consider these peripheral differences between the two:&nbsp; The 371 has a very different PLL and method of programming it.&nbsp; The SHI is a synchronous serial peripheral only whereas the SCI on the 56311 has synchronous and asynchronous modes.&nbsp; The ESAI's on the 56371 are very different from the ESSI's on the 56311.<BR /><BR /><BR /><BR /><BR /><DIV></DIV></BODY></HTML> Sat, 01 Sep 2007 05:18:20 GMT https://community.nxp.com/t5/Other-NXP-Products/DSPAUDIOEVM-with-DSP56371-How-to-control-via-RS232/m-p/141007#M254 david_dicarlo 2007-09-01T05:18:20Z
