| - | ===== Supported DAI formats | + | ===== PLL Configuration ====== |
| + | |||
| + | The ADAU1373 features two PLLs: | ||
| + | |||
| + | <code c> | ||
| + | enum adau1373_pll { | ||
| + | ADAU1373_PLL1 = 0, | ||
| + | ADAU1373_PLL2 = 1, | ||
| + | }; | ||
| + | </ | ||
| + | |||
| + | Each PLLs input frequency can be selected from a variety of signals: | ||
| + | <code c> | ||
| + | enum adau1373_pll_src { | ||
| + | ADAU1373_PLL_SRC_MCLK1 = 0, | ||
| + | ADAU1373_PLL_SRC_BCLK1 = 1, | ||
| + | ADAU1373_PLL_SRC_BCLK2 = 2, | ||
| + | ADAU1373_PLL_SRC_BCLK3 = 3, | ||
| + | ADAU1373_PLL_SRC_LRCLK1 = 4, | ||
| + | ADAU1373_PLL_SRC_LRCLK2 = 5, | ||
| + | ADAU1373_PLL_SRC_LRCLK3 = 6, | ||
| + | ADAU1373_PLL_SRC_GPIO1 = 7, | ||
| + | ADAU1373_PLL_SRC_GPIO2 = 8, | ||
| + | ADAU1373_PLL_SRC_GPIO3 = 9, | ||
| + | ADAU1373_PLL_SRC_GPIO4 = 10, | ||
| + | ADAU1373_PLL_SRC_MCLK2 = 11, | ||
| + | }; | ||
| + | </ | ||
| + | |||
| + | The input frequency must configured to be between 7813 and 27000000 Hz. The output frequency must be configured to be between 45158000 and 49152000. Configuring the PLL with other input or output frequency will fail. | ||
| + | |||
| + | The PLL runs at 1024 times the base sample rate. So for a 48000 Hz based sample rate you'd normally choose 49152000 Hz for the PLL output frequncey and for a 44100 Hz based sample rate 45158400 Hz. | ||

| + | ===== DAI configuration ===== | ||

| - | ===== Adding | + | ===== Kernel |
| - | Skip this section if you want to build the driver into the kernel directly. | + | |
| - | To add support for codec ADAU1373 to the kernel build system, a few things must be enabled properly for things to work.The configuration is as following: | + | |
| < | < | ||
| - | Linux Kernel Configuration | + | Device Drivers |
| - | | + | [*] I2C support |
| - | | + | [*] I2C Hardware Bus support |
| - | < | + | *** I2C system bus drivers |

| - | <*> Blackfin | + | |
| </ | </ | ||
| - | Doing this will create modules (outside the kernel). The modules will be inserted automatically when it is needed. You can also build sound driver into kernel. | + | ===== Hardware configuration ===== |
| + | Connect the STAMP SPORT 0 port (P6) to the EVAL-ADAU1373 J23 and J28 headers. | ||
| - | ==== Testing | + | Note that the SPORT has separate signals for the capture and playback clocks, while the ADAU1373 uses the same clock signals for both, so the EVAL-ADU1373 clock signal pins need to be connected to two STAMP pins each. |
| - | If audio is configured as modules, skip this section. If audio is built into kernel and you have booted the kernel, there are a few things to check to ensure audio is working: | + | ^ STAMP pin ^ EVAL-ADAU1373 pin ^ Function ^ |
| + | | P6-26 (SPORT 0 - PJ2_SCL) | J23-1 | I2C SCL | | ||
| + | | P6-24 (SPORT 0 - PJ3_SDA) | J23-3 | I2C SDA | | ||
| + | | P6-6 (SPORT 0 - PJ9_TSCLK0), P6-16 (SPORT 0 - PJ6_RSCLK0) | J28-6 (A_BCLK) | BCLK | | ||
| + | | P6-11 (SPORT 0 - PJ10_TFS0), P6-7 (SPORT 0 - PJ7_RFS0) | J28-8 (A_LRC) | LRCLK | | ||
| + | | P6-14 (SPORT 0 - PJ11_DT0PRI | J28-10 (A_DACDAT) | Playback data | | ||
| + | | P6-8 (SPORT 0 - PJ8_DR0PRI) | J28-12 (A_ADCDAT) | Captrue data | | ||
| + | | P6-33 | J28-1 | GND | | ||
