Forum Post: RE: BQ24195 PMID

Charles Mauney — Mon, 20 May 2013 12:24:00 GMT

In charge mode, Q1, is on and is used as a sense resistor, so the voltage difference between VBUS and PMID is less than 100mV.

In boost mode Q1 is off.

Forum Post: TROUBLE INTERFACING STELLARIS SSI with INTEL 8051 SSR PROTOCOL

Mohit Hada — Mon, 20 May 2013 12:15:00 GMT

Hi, I am using LM3S9B96 from stellaris arm cortex controllers.

I want to interface SSI interface of this Serial Interface of AD9951 DDS Controller which works on Intel 8051 SSR protocol.

Can this be done using SSI?

I am finding the protocols to be different and do not find any format of Stellaris SSI interface matching with this.

Please help to find a suitable protocol for this problem or else we have to design a total software solution for this.

Thanks and Many Regards.

Forum Post: C6678 MSMCSRAM setting ?

Stellar Respree — Mon, 20 May 2013 12:15:00 GMT

As for TI6678 memory map, MSMCSRAM area is 0x0c00_0000 - 0x0c3f_ffff.

And I want to reduce MSMCSRAM 0x0c00_0000 - 0x0c1f_ffff and use 0x0c20_0000 - 0x0c3f_ffff exclusive.

The reason for this setting is I want to use upper half of MSMCSRAM area for PCIe DMA area (for my own application)

and I do not want QMSS or CPPI or another shared resource collide with my DMA data.

So my question is:

1. Could this be a accaptable approach? (devide MSMCSRAM area) ?

2. How can I change MSMCSRAM area to 0x0c00_0000 - 0x0c1f_ffff ?

Regards,
Stellar

You could try to remove the comments. Rebuild the gstreamer.

You could use these pipelines for tests:

gst-launch -v videotestsrc ! 'video/x-raw-yuv, width=1920, height=1080, format=(fourcc)NV12, framerate=60/1' ! omx_mpeg4enc ! filesink location=colorbar.mp4

Forum Post: RE: Output of DAC3152

Jim Seton — Mon, 20 May 2013 12:08:00 GMT

Prashant,

The output transformer on the DAC3152 has a minimum input frequency of 300KHz. You are operating at 4KHz. You are just seeing the effects of the transformer, which is acting like a capacitor at this low data rate. Try increasing your date rate to at least 1MHz to get a valid square wave from this evm. If you must operate at such a low data rate, you will need to remove the transformer or find one with a lower input bandwidth.

Regards,

Jim

Forum Post: RE: C6455 system trace set up

Chao Hu — Mon, 20 May 2013 12:04:00 GMT

Thank you very much for your reply.

So can I still use Spectrum Digital XDS560V2 PRO STM USB emulator to trace analyzes C6455?

I tried not to add CSSTM to the target configuration file, and apply the similar process that I used to C6678. Open trace control window (in CCS5.3), under tab ot C64XP-0, select PRO trace as receiver, and set buffer size as smallest (64k), then click "OK". The tool started programming the trace emulator and calibrating circuits at various frequencies, it passed a few calibration frequencies, but always fails at a lower frequency around 125M.

The failure is "Failed to calibrate the circuit for C64XP_0: calibration failed at 124.927MHz for C64XP_0: failed margin test". What does this mean?

Is there any document or wiki details the procedure?

Regards,

Chao Hu

Forum Post: RE: About LMH1982

John White1 — Mon, 20 May 2013 11:56:00 GMT

Hi Alan,

I understand from the data sheet that there is a suggested sequence that the registers should be programmed.

Is there a way of showing the sequence and register values that are generated when using the LMH1982 Application v2.0 program without using the USB interface, as I do not have an evaluation board.

This sequence information would make it far easier to program the LMH1982 using the I2C interface of the microcontroller.

Forum Post: RE: Clean MSP430g2553 library for I2C Communication with ITG3200 gyroscope

Barışcan Kayaoğlu — Mon, 20 May 2013 11:49:00 GMT

Hello again.

I fixed my problem by changing some parts in the Receive function. Thanks to Chester Gillon's post, it made me realise that STT interrupt occurs right after the slave ACK the master. After checking the user guide carefully, i found this:

If a master wants to receive a single byte only, the UCTXSTP bit must be set while the byte is being
received. For this case, the UCTXSTT may be polled to determine when it is cleared:

So this STOP condition must occur after the ACK but before the second data ACK. So i changed my receive function into this and it solved all my problems:

uint8_t Receive(char registerAddr){
uint8_t receivedByte = 0;
while (UCB0CTL1 & UCTXSTP); // Ensure stop condition got sent
UCB0CTL1 |= UCTR + UCTXSTT; // I2C start condition with UCTR flag for transmit
while((IFG2 & UCB0TXIFG) == 0); //UCB0TXIFG is set immidiately
UCB0TXBUF = registerAddr; //write registerAddr in TX buffer
while((IFG2 & UCB0TXIFG) == 0); // wait until TX buffer is empty and transmitted
UCB0CTL1 &= ~UCTR ; // Clear I2C TX flag for receive
UCB0CTL1 |= UCTXSTT; // I2C start condition with NACK for single byte reading
while (UCB0CTL1 & UCTXSTT); // Start condition sent? RXBuffer full?
UCB0CTL1 |= UCTXSTP;
while((IFG2 & UCB0RXIFG) == 0); // wait until TX buffer is empty and transmitted
receivedByte = UCB0RXBUF; // I2C stop condition
return receivedByte;
}

1105: gDRV_ipipeObj.boxcarConfig.oneShotEnable = FALSE;
1179: gDRV_ipipeObj.ipipeSetup.oneShotEnable              = FALSE;

Which of the various FPS's should I try reducing? I guess reducing the encode FPS with frame skipping as we cannot drop our input FPS (camera runs at 1080p30).

Nitish,

I am facing issues in syslink similar to the ones I see in this thread, so your solution above might hold some promise for me. The link you have pasted above (point 1) looks broken, could you please post the content again? Also, I am working on a Codec Engine based DSP application (C674 DSP on DM8169), as per you point 2 should I use firmware loader to load the DSP image?

Hi,

Thank you for your answer again. You are right. I haven´t handled the oscillator fault and in consequence REFO take over (which accuracy is unluckily worse).

Finally, I´ve a problem for manage the oscillator fault. As I said in the last post, I use that code which solve the problem (in first view) but in some situations there are flags which can´t be removed (XT1LFOFFG, DCOFFG…) and in consequence my program still in the loop.

I don´t know if there are any tip in this situation ( like stop oscillator, restart oscillator…). Thank you for your time!
