PCM3070 SPI problems

Hi Ignasi,

Pin 12 is the SPI_ SELECT pin, this determines if I2C or SPI communication is used. If this pin is high it will be in SPI mode, if low then it will be in I2C mode. What setting do you have this pin at?

Justin

Hello Justin,

SPI_SELECT is 1.

Thank's for your help,

In case it helps, here I join the code of my msp430, trying to communicate unsuccesfully with the pcm3070

errata: MSP340 and not msp3040

And the codec pcm3070 is connected with this schematics :

And the microcontroller . I cannot make them to communicate properly.

Hi Ignasi,

It seems you are setting the SSZ pin as an input on the MSP430, this pin must be driven to let the PCM3070 know when SPI communication is coming. Please read section 2.7.2 in www.ti.com/.../slau332.pdf

Justin

Hello Justin!

Thank's for your help. After another reading again the section 2.7.2 it is clear for me that ssz must be driven. The problem I have right now, It is I don't know how to implement it on my code. Could you help me on this? A simple GPIO_setOutputHighOnPin() should work? If so, where should I implement it?

I changed the port to output with the function GPIO_setAsPeripheralModuleFunctionOutputPin(), but it still doesn't work. Any other bugs?

Thank you all for you help,

ip

Hi Ignasi,

The application document states:
"The SSZ pin can remain low between transmissions; however, the PCM3070 only interprets the first 8 bits transmitted after the falling edge of SSZ as a command byte, and the next 8 bits as a data byte only if writing to a register."

So you need to create a falling edge on the SSZ line at the start of every transmission.

Justin

Dear Justin,

So in the code below, how should I create the falling edge on the ssz line?

//PCM3070 SPI SS
GPIO_setOutputLowOnPin(GPIO_PORT_P2, GPIO_PIN5);

But it doesn't act as a falling edge. Where should this line be? 

Thank's you a lot in advance.

Best Regards

ip

Dear Justin,

So in the code below, how should I create the falling edge on the ssz line? Now I have the following line, but it doesn't drive.

//PCM3070 SPI SS

(this code still doesn't work on spi )

Hi Ignasi,

Have you checked the SPI output with a sniffer to verify the MSP430 is outputting the correct values? Do you have the PCM3070 EVM? If so you could use the GUI to talk over SPI and use a sniffer and compare the GUI/EVM output to your custom setup.

For detailed support on the MSP430 code you will have to head over to the MSP430 forum : e2e.ti.com/.../166

Hello Justin,

Thank's for your help.

I can check using an oscilloscope, that clk from spi is ok, and mosi got some data travelling throught it. On the other hand, miso is always blocked to 1. Unfortunatly, I don't have pcm3070 evm, so I couldn't do the sniffing over gui.

I have chosen this product after using it on a evm c5517, but on this case, we were running on I2C and worked good using the example. If you have any other idea, please tell me. I would be very glad to find the bug!

Best regards

Hi IP,

What is the behavior of the slave select line?

Justin

Hello Justin,

Unfortunatly, I don't have access to ste. 

I'm exploring a new option, sending a communication package to my pcm3070 requesting an answer, to see if it's dead or not. But I couldn't find any example about it in spi. Right now, to be honest, I'm so lost I don't know what else to do.

Thank you for your help in advance

I enclose to you the last version of my code :

Last update, now I don't have signals at all outside my msp430. No bus, no clock..

Hi Ignasi,

It seems you need to verify your SPI operation on the MSP430. You can head over to the MSP430 forum on E2E for help with getting SPI working.

Justin

Hello Justin,

Thank's for your help.

After your first recommendation on the MSP430 forum, I created a post with all the documentacion on the problem, and my advances. Unfortunatly, I couldn't have any answer on the topic.

Best Regards

ip

Hello Justin,

Thank's for your help. 

Could you please confirm me that you don't see any design problem on the PCM3070? Voltage, Grounding, Capacities.... In case it doesn't work because a wrong wiring...

Thank you in advance!

ip

Hi IP,

I have looked over the schematic again and I have a few comments:

-many of the mode select pins are driven by the MSP430, so making sure they are set correctly with a probe when testing could be helpful. (along with the SS pin)
-You are supplying AVDD with VBAT, is this a regulated supply?
-I don't see any filtering on the input, only DC blocking caps, unless there are filters elsewhere.

Everything else looks good.

Justin

Hello Justin,

Thank's again for your support.

- I have tested the selected pins driven by MSP430, and they are all ok, related to configuration.

- AVdd is a regulated supply. On my case, regulated 1.8V

- Filters are on another part of the design. On the board, they are close to codec.

I couldn't have any help on MSP340 forum. From my side, I just had some advances, I could see my spi signals on oscilloscope, so spi is alive. The thing is I try to configure a single beep on the outside, to confirm it is alive. But I couldn't. With my actual spi bus I still cannot program the registers. Maybe spi parameters are wrong?

UCB3CTL1 |= UCSWRST; // **Put state machine in reset**
UCB3CTL0 |= UCMST+UCSYNC+UCCKPL+UCMSB; // 3-pin, 8-bit SPI master
// Clock polarity high, MSB
UCB3CTL1 |= UCSSEL_2; // SMCLK
UCB3BR0 = 0x02;///0x02; // /2
UCB3BR1 = 0; //
UCA0MCTL = 0; // No modulation. Just needed on UCA0, no on ucb3
UCB3CTL1 &= ~UCSWRST; // **Initialize USCI state machine**
UCB3IE |= UCRXIE+UCTXIE; // Enable USCI_B3 RX interrupt

Working with the Clock on 8 MHz.

The configuration of the codec, pretending to have a Beep on the output LOL is the following :

Here the information on filtering stage :

Hi IP,

I believe there is a difference in meaning between SPI settings in the MSP430 documentation and the PCM3070 definitions. Try changing the following code:

From:
UCB3CTL0 |= UCMST+UCSYNC+UCCKPL+UCMSB; // 3-pin, 8-bit SPI master

To this:
UCB3CTL0 |= UCMST+UCSYNC+UCMSB; // 3-pin, 8-bit SPI master

If this does not correct the SPI communication I would suggest using the EVM and using your script through one of our GUIs to test the script itself without the complication of the SPI communication.

Justin
