Rockbox Ports are now being developed for various digital audio players!
We have to use I2C interface to read/write to device control registers.
We have to setup DMA for writing actual PCM samples.
I triedi2c_readmem(I2C_AUDIO_ADDRESS, 0xB, buf, 1);//int i2c_readmem(int device, int address, unsigned char* buf, int count )Default value after reset of this register is 0xFF as per datasheet.But the i2c_readmem is failing. it is not getting i2c_getack() after writing device value.
Do we have to enable the WM8985 chip??
Also in general how are we finding the base addresses of the devices??
