There are two ways to use this * macro: * AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default) * AUDIOHW_SETTING(name, unit, nr_decimals, step, min, max, default, expr) * * It is important to understand that each setting has two scales: the hardware * scale and the user scale. In the first form of the macro, they coincide. * In the second form, the conversion from hardware to user is done by the * expression [expr] provided in the extra argument (see examples below). The * hardware scale ranges from [min] to [max], in steps of [step]. The default value * is [default]. Furthermore, when displaying the value to the user, [nr_decimals] * gives the number of decimal points to display. Thus if [nr_decimals] is 0 then * a value of x means x [unit]. If [nr_decimals] is 1 then a value of x means * x/10 [unit] and so on. Note that both [nr_decimals] and [unit] are irrelevant * to the hardware, they simply provide a flexible way to show natural value to * the user. When you want the user scale to be different than the hardware scale, * you must provide [expr], an expression that can use the variable "val", which * represents the hardware value, and converts it to the user value. The [expr] * can involved a function call in very complicated/nonlinear cases, as long as * the function does not have any side-effect. Finally, the [name] parameter * must be one of the settings listed in audiohw_setting.h * * Examples: * * AUDIOHW_SETTING(VOLUME, "dB", 0, 1, -100, 12, -25) * This describes the volume setting. The values are in dB (no decimal). The * minimum value is -100 and the maximum is 12, with a step of 1 and a default * value of -25. This means that the hardware can take any of the following value: * -100, -99, -98, ..., 11,12 * Since there is are decimals and no conversion expression, a hardware value of * x means x dB. So a value of -25 means -25 dB, a value of 5 means 5 dB. * WARNING VOLUME is actually special: whatever scale you choose, the sound code * will always set the volume by calling audiohw_set_volume() with a centibel * value (ie it will not perform any conversion). Thus it is strongly advised * that you always choose a VOLUME scale with precision 1 (centibels) and no * hardware conversion. * * AUDIOHW_SETTING(MDB_CENTER, "Hz", 0, 10, 20, 300, 60) * This describes the MDB (dynbamic bass) center. The values are in Hz (no * decimal). The minimum value is 20 and the maximum is 300, in steps of 10 * and a default of 60. Thus hardware can take any of the following value: * 20, 30, 40, ... 290, 300 * Since there are no decimals and no conversion expression, a hardware of x * means x Hz. So a value of 60 means 60 Hz. * * AUDIOHW_SETTING(BASS, "dB", 1, 15, -60, 90, 0) * This describes the bass control. Since there is one decimal, the values are * in tenth of dB. The minimum value is -60 and the maximum is 90, in steps of * 15 and a default value of 0. Thus hardware can take any of the following value: * -60, -45, -30, ... 60, 75, 90 * Since there is one decimal, a hardware value of x means x/10 Hz. So a value * of 60 means 60/10 = 6 dB. A value of -45 means -45/10 = -4.5 dB. * * AUDIOHW_SETTING(DEPTH_3D, "%", 0, 1, 0, 15, 0, (100 * val + 8) / 15) * This describes 3D enhancement control. The values are in percentage (no * decimal). This setting makes a difference between hardware and user scale. * The minimal hardware value is 0 and the maximum is 15, in steps of 1 and * a default of 0. Thus hardware can take any of the following value: * 0, 1, 2, ... 14, 15 * Because of the conversion expression, a hardware value of x means * (100 * val + 8) / 15) %. A hardware value of 0 means (100 * 0 + 8) / 15) = 0 % * because the result must be an integer (8 / 15 = 0). A hardware value of 1 * means (100 * 1 + 8) / 15 = 7 %. A hardware value of 15 means * (100 * 15 + 8) / 15 = 100 %. In fact, from the user point of view, the range * of available values is: * 0%, 7%, 13%, 20%, ..., 93%, 100% * * AUDIOHW_SETTING(LEFT_GAIN, "dB", 2, 15,-345, 1200, 0, val * 5) * This describes the left gain. Since there are two decimals, the values are in * hundredth of dB. This setting makes a difference between hardware and user scale. * The minimal hardware value is -345 and the maximum is 1200, in steps of 15 and * a default of 0. Thus hardware can take any of the following value: * -345, -330, -315, ..., 1185, 1200 * Because of the conversion expression, a hardware value of x means * val * 5 hundredth of dB or, in other words, (val * 5)/100 dB (where we keep two * decimals). A hardware value of -345 means -345 * 5 = -1725 hundredth of dB * = -17,25 dB. A value of -330 means -330*5 = -1650 hundredth of dB = -16,50 dB. * A value of 1200 means 1200 * 5 = 6000 hundredth of dB = 60 dB. In fact, * from the user point of view, the range of available values is: * -17.25 dB, -16.60 dB, ..., 59.25 dB, 60dB. * * AUDIOHW_SETTING(DEPTH_3D, "dB", 0, 1, 0, 3, 0, depth3d_phys2_val(val)) * This describes 3D enhancement control. The values are in dB (no * decimal). This setting makes a difference between hardware and user scale. * The minimal hardware value is 0 and the maximum is 3, in steps of 1 and * a default of 0. Thus hardware can take any of the following value: * 0, 1, 2, 3 * Because of the conversion expression, a hardware value of x means * depth3d_phys2_val(x) dB. If for example the conversion functions is: * int depth3d_phys2_val(int val) * { * return val == 0 ? 0 : val * 5 + 30; * } * then from the user point of view, the range of available values is: * 0 dB, 35 dB, 40 dB, 45 dB */ #define AUDIOHW_SETTING(name, us, nd, st, minv, maxv, defv, expr...) \ static const struct sound_settings_info _audiohw_setting_##name = \ { .unit = us, .numdecimals = nd, .steps = st, \ .minval = minv, .maxval = maxv, .defaultval = defv };
