ADSP 219x SPORT disable/enable

Hello! We're using SPORT in multichannel autobuffer mode, SCLK and TFS/RFS are generated externally. After some special signal becomes high (let's call it RESET) SCLK/TFS/RFS are masked and SPORT should be disabled by DSP. When RESET becomes low SPORT needs to be reenabled. But after reenabling SPORT we have some corrupted data at DT. And (as we suppose) because RESET is async with DSP ...

I have a question about the TFS signal of an SPORT in an ADSP 21061: I set up the TFS of SPORT 1 as follows: Internally generated (ITFS = 1), data independent (DITFS = 1), late (LAFS = 1), active low (LTFS=1). When SPORT is enabled it works as expected

compatibility between adsp2181 and bf533

Hi friends ADSP 2181 and BF533 are not compatible. ADSP2181 is a 5V logic(TTL) while BF533 is a 3.3V logic device. If i need to connect ADSP2181 sport to BF533 sport is it enough if i use a voltage divider for level shifting? If not which level shifter IC is ideal in this case? I need to level shift all 5 signals on ADSP2181 sport i.e DT,DR,TFS,RFS,SCK.

hi all Am trying to implement sport comm between ADSP2181 and BF533. My aim is to send memory contents of adsp2181 to bf533 memory via sport. On 2181 i have disabled codec to use sport0. 2181 clock is generated internally. For bf533 clock is externaland am using sport0 of board. ADSP2181 transmits and BF533 receives. First of all which program should run first. Is it ADSP2181 because its...

Hello Everyone, I am developing an audio application using Blackfin BF537 EzKit lite. I have some problems with DAC 1854 Sport interface. I want to pass the audio data samples via SPORT interface to DAC 1854 without using DMA. I am writing to Sport 0 Tx register on receiving the SPORT0_TX interrup as follows *pSPORT_TX=*(audio_data); Should I need wait to check any status register of SPO...

SPORT-UART communication with TxFs

Hi, I am tying to communicate with a UART device though my SPORT. My TxFs and RxFs are connected, also the clock is generated by the DSP and fowwloed by the UART device. What I have to do is that, after tansmission and reception of 9 bytes I have to stop transmission and receptions for some time, and then re enable them again. For this purpose I am disabling the SPORT in my receive interrupt be...
21065L Sport interrupt held off?

I have an instance where I intermittently lose sport data. I am using an AKM codec that interleaves two channels into sport 0 on the 21065L. This works perfectly. I get 16 sets of bits, each coming in and giving me an interrupt every 142us. Runs for hours. Then, for some odd reason, the interrupt waits for 151us, which is after a 17th set of bits came through. When I look at the data then, I ...

Hi, I have implemented on ADSP-21261 a serial tx rx by use of sport, how suggested in the application note EE191: At rx I set the clock of the SPORT for oversampling the freq. of serial communication by 3: //bit rate 9.9 kbit/s --> freq of oversampling = 9.9 k * 3 = 28.8 kbit/s //CLKDIV3 = [fCCLK(147,456 MHz)/4 x SPORT_CLK(28.8 kHz)] - 1 = 1279

Hello, Alex, It is understandable that the SPORT needs to be disabled (stopped) before any configuration changes on it. What I dont understand is why you need to disable, then wait for the famous delay, then re-enable the SPORT again, as if you had to make any changes...
