Instead, we define 6 ADC channels for the Arduino header pins * A0-A5, one channel for V_REFINT and one channel that is used for the * STMod+ header pin STMOD+_ADC or the DAC1 output if `periph_dac` is used. * * The pin assignment can be found in board's user manual in Table 15, page 26 * (Arduino compatible connectors) and Table 26, page 35 (32L496GDISCOVERY * Discovery board I/O assignment). These tables are showing pin assignments and * information about ADC - a text similar to `ADC[X]_IN[Y]`, where: \n * `[X]` - describes used device - indexed from 0, * for example `ADC3_IN13` is device 2, \n * `[Y]` - describes used channel - indexed from 1, * for example `ADC3_IN13` is channel 13 * * Channels shared by multiple ADCs are referred to as `ADC[XXX]_IN[Y]`. * `ADC12_IN13` means for example that channel 13 can be used either with ADC1 * or with ADC2. * * Output from internal reference voltage V_REFINT is connected to ADC1 * channel 0. * * The V_REF+ pin is not connected to an external reference voltage on the * board by default. Instead the the VREFBUF must be used (`VREFBUF_ENABLE=1`). * The output voltage of VREF is around 2.048 V in this case. * * If an external reference voltage is used as V_REF+, either by soldering * R18 to use V_DDA as reference voltage or by using the AVVD pin of the * Arduino connector by closing the solder bridge SB2, the VREFBUF must not * be enabled by defining `VREFBUF_ENABLE=0`. * * @{ */ static const adc_conf_t adc_config[] = { { .pin = GPIO_PIN(PORT_C, 4), .dev = 0, .chan = 13 }, /* A0, ADC12_IN13 */ { .pin = GPIO_PIN(PORT_C, 1), .dev = 0, .chan = 2 }, /* A1, ADC123_IN2 */ { .pin = GPIO_PIN(PORT_C, 3), .dev = 0, .chan = 4 }, /* A2, ADC123_IN4 */ { .pin = GPIO_PIN(PORT_F, 10), .dev = 2, .chan = 13 }, /* A3, ADC3_IN13 */ { .pin = GPIO_PIN(PORT_A, 1), .dev = 0, .chan = 6 }, /* A4, ADC12_IN6, SB26 closed */ { .pin = GPIO_PIN(PORT_C, 0), .dev = 1, .chan = 13 }, /* A5, ADC12_IN13, SB28 closed */ { .pin = GPIO_UNDEF, .dev = 0, .chan = 0 }, /* V_REFINT, ADC1_IN0 */ { .pin = GPIO_UNDEF, .dev = 0, .chan = 18 }, /* V_BAT, ADC1_IN18 */ #ifndef MODULE_PERIPH_DAC { .pin = GPIO_PIN(PORT_A, 4), .dev = 0, .chan = 9 }, /* STMOD+_ADC, ADC12_IN9 */ #else { .pin = GPIO_UNDEF, .dev = 1, .chan = 17 }, /* DAC1, ADC2_IN17 */ #endif }; /** * @brief Number of ADC devices */ #define ADC_NUMOF ARRAY_SIZE(adc_config) /** * @brief V_BAT ADC line */ #define VBAT_ADC ADC_LINE(7) /** * @brief V_REFINT ADC line */ #define VREFINT_ADC ADC_LINE(6) /** * @brief Enable VREFBUF as V_REF+ * * If an external reference voltage is used as V_REF+, either by soldering * R18 to use V_DDA as reference voltage or by using the AVVD pin of the * Arduino connector by closing the solder bridge SB2, the VREFBUF must not * be enabled by defining `VREFBUF_ENABLE=0`. */ #ifndef VREFBUF_ENABLE #define VREFBUF_ENABLE (1) #endif /** @} */ /** * @name DAC configuration * * The V_REF+ pin is not connected to an external reference voltage on the * board by default.
