  • Forum Post: I2S connect with Audio Codec hardware design

    Caroline Wang
    Dear all, Our Cortex-M3 has I2S and I2C connect with TLV320AIC23BPW in DK-9B96 EVM. Schematics page 29, Cortex-M3 I2S provide both TXMCLK and RXMCLK but it seems TLV320AIC23BPW only has one MCLK. So my customer needs both I2S In and out, is that okay just connect only one I2STXMCLK or I2SRXMCLK provide...

  • Forum Post: I2S-Interface initialisation LM3S9B92

    A.Wenzel
    Hi, at the moment I'm trying to get the audio-codec on my evalbot to work. I'm using the following code: void init_codec() { volatile unsigned int i; // HW-Initialisieren // GPIO -> Analog-Reset SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOA); GPIOPinTypeGPIOOutput(GPIO_PORTA_BASE, GPIO_PIN_7...

    Keren Danon
    Hi, I'm using the EKI LM3S9B92(Rev B1) and I would like to use the uDMA for the I2S. I took the I2S_demo example for the B96 and modified it to the B92, but it's not working. I've noticed that the corresponding bit(bit 29 for Tx) on the DMAENASET register is not set when I change...

    Sebastian Meisner
    Hi everyone! I'm using a Stellaris Evalbot with Code Composer Studio and the Audio Demo delivered with the Evalbot Stellarisware package. I added an audio recording function to the audio demo. I set up the uDMA controller and configured the audio codec accordingly, but all i get into my I2S_RXFIFO...

  • Forum Post: I2S Rx on LM3SB90

    Ryan Hunt
    Hello, I am attempting to configure I2S on the Stellaris LM3S9B90. I have used several forum discussions on here, as well as documentation, to create my program. I am using an external ADC set as the master and the Rx module on the Steallaris set as the slave. The whole system is driven by an external...

  • Forum Post: Using LM3S9B96 to generate MCLK for I2S digital audio data

    Chi-wen Wang
    Hi All, We are working on a 2.1 channel audio amp with TAS5508C. (It is a long story on why we use an 8-channel controller for 2.1 design.) There are several audio sources: I2S out from LM3S9B96 and an BT module. LM3S9B96 provides its own master MCLK and I2S data so we are fine here. However, the...
