Tuan PM	f91715438a	i2s: return error code if register isr error, resolve #587 (github) ... set p_i2s_obj = NULL when return error	2017-06-13 14:28:47 +07:00
Wangjialin	f68c5baea6	bugfix(i2s): fix error when changing changel number in i2s_set_clk function	2017-05-23 19:32:10 +08:00
Wangjialin	1f055d28b8	Driver update: I2S pdm and built-in DAC ... 1. Modify I2S DAC built-in mode settings 2. Add I2S pdm mode 3. Correct I2S signal index in full-duplex mode 4. Modify dac output function 5. Add dac pad init functions 6. Modify DAC documentation 7. Add i2s_set_dac_mode API	2017-05-12 16:21:02 +08:00
Tuan PM	fc1ee2666a	I2S: fixed support for 24 and 32-bits, fixed tx/rx at the same time and others in log: ... Add support 24, 32 bits @jxmao optimize i2s_zero_buffer @jxmao correct config support slave mode @jxmao correct setup pin support tx/rx at the same time Enhance pin power @jxmao add dynamic change number of channels remove nvs_init remove start log and enhance power pin setup using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params validate i2s_bits_per_sample and channel check tx & rx buffer before fill zero remove checking channel as @jxmao suggest limit dma buffer modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512 Add support 24, 32 bits reduce push function Modify sample can test with 24, 32-bits Add i2s sample README Fixed i2s_set_clk got reset sometime can changes bit-wide while running Fix sample rate calculation for DAC mode from @jeroen modify example can change bits per sample every 5 seconds cleanup add comment for bytes_per_sample update as @angus suggestions Add i2s_set_clk api I2S driver bug fixed as following log: @jxmao optimize i2s_zero_buffer @jxmao correct config support slave mode @jxmao correct setup pin support tx/rx at the same time Enhance pin power @jxmao add dynamic change number of channels remove nvs_init remove start log and enhance power pin setup using enum for i2s_channel and i2s_bits_per_sample, return ESP_ERR_INVALID_ARG when check params validate i2s_bits_per_sample and channel check tx & rx buffer before fill zero remove checking channel as @jxmao suggest limit dma buffer modify i2s pin back to gpio mux before configure gpio matrix, resolve github issue #512 limit dma buffer to 4092 change gpio_matrix_*_check to inline function, remove some comments and rename test_i2s function to setup_triangle_sine_waves for change commit title	2017-04-27 10:00:10 +07:00
