EE-191 Software UART for ADSP21262 - bobkruse1501 - Sep 29 16:44:00 2005
Hi,
Has anyone translated the assembly code for Analog Devices
EE191 "Implementing a Glueless UART Using the Sharc DSP SPorts" from
it's ADSP-21161 to the newer ADSP-21262 and ADSP21363? The SPort
interrupt registers changed with the part change.
Before I re-wrote it, I thought I'd see if anyone had one they felt
like sharing.
Thanks
Bob

Re: EE-191 Software UART for ADSP21262 - dusk...@volja.net - Dec 21 16:39:00 2005
Hi!
I want to implement MIDI interface on EZ-KIT lite with ADSP21262, yust the RX part. So I thougt that code from EE-191 would work, but there are differences between processors.
Would this routing of signals thru SRU be correct, if the incoming data signal is on DAI pin 1 (SPIDF is disconnected on SW8) and uses SPORT5B:
// Connect the RX to SPORT5, using data input B
// data in on DAI pin 1
SRU(DAI_PB01_O, SPORT5_DB_I);
// Frame sync in on pin 3
SRU(DAI_PB01_O, SPORT5_FS_I); //------------------------------------------------------------------------
// Tie the pin buffer enable inputs LOW for DAI pin 1so
// that it is always input pin.
// Tie the pin buffer input LOW.
SRU(LOW, DAI_PB01_I);
// Tie the pin buffer enable input LOW
SRU(LOW,PBEN01_I);
Has anyone successfully ported code from EE-191 to 21262?
Thanks,
Duskos
