iio: dac: add support for stm32 DAC

2017-04-14T15:36:16Z

Add support for STMicroelectronics STM32 DAC. It's a 12-bit, voltage output digital-to-analog converter. It has two output channels, each with its own converter. It supports 8 bits or 12bits left/right aligned data format. Only 12bits right-aligned is used here. It has built-in noise or triangle waveform generator, and supports external triggers for conversions. Each channel can be used independently, with separate trigger, then separate IIO devices are used to handle this. Core driver is intended to share common resources such as clock, reset, reference voltage and registers. Signed-off-by: Fabrice Gasnier Signed-off-by: Jonathan Cameron

iio: dpot-dac: DAC driver based on a digital potentiometer

2016-11-13T13:07:15Z

It is assumed that the dpot is used as a voltage divider between the current dpot wiper setting and the maximum resistance of the dpot. The divided voltage is provided by a vref regulator. .------. .-----------. | | | vref |--' .---. | regulator |--. | | '-----------' | | d | | | p | | | o | wiper | | t |<---------+ | | | | '---' dac output voltage | | '------+------------+ Signed-off-by: Peter Rosin Signed-off-by: Jonathan Cameron

iio: stx104: Add IIO support for the ADC channels

2016-09-03T16:25:53Z

The Apex Embedded Systems STX104 features 16 channels of single-ended (8 channels of true differential) 16-bit analog input. Differential input configuration may be selected via a physical jumper on the device. Similarly, input polarity (unipolar/bipolar) is configured via a physical jumper on the device. Input gain selection is available to the user via software, thus allowing eight possible input ranges: +-10V, +-5V, +-2.5V, +-1.25V, 0 to 10V, 0 to 5V, 0 to 2.5V, and 0 to 1.25V. Four input gain configurations are supported: x1, x2, x4, and x8. This ADC resolution is 16-bits (1/65536 of full scale). Analog input samples are taken on software trigger; neither FIFO sampling nor interrupt triggering is supported by this driver. The Apex Embedded Systems STX104 is primarily an analog-to-digital converter device. The STX104 IIO driver was initially placed in the DAC directory because only the DAC portion of the STX104 was supported at the time. Now that ADC support has been added to the STX104 IIO driver, the driver should be moved to the more appropriate ADC directory. Signed-off-by: William Breathitt Gray Signed-off-by: Jonathan Cameron

iio: dac: AD8801: add Analog Devices AD8801/AD8803 support

iio: Add IIO support for the Measurement Computing CIO-DAC family

2016-07-24T18:58:43Z

The Measurement Computing CIO-DAC is a family of 16-bit and 12-bit analog output devices. The analog outputs are from AD660BN/AD7237 converters with each output buffered by an OP-27. Voltage ranges are configured via physical jumpers on the device. This driver does not support the devices' simulataneous update mode; the XFER jumper option should be deselected for all analog output channels. This driver provides IIO support for the Measurement Computing CIO-DAC family: CIO-DAC16, CIO-DAC08, and PC104-DAC06. The base port addresses for the devices may be configured via the base array module parameter. Signed-off-by: William Breathitt Gray Signed-off-by: Jonathan Cameron

iio: Add IIO support for the DAC on the Apex Embedded Systems STX104

2016-02-13T20:54:14Z

The Apex Embedded Systems STX104 is a 16-channel 16-bit analog input and 2-channel 16-bit analog output PC/104 card. The STX104 incorporates a large one mega-sample FIFO. This driver provides IIO support for the 2-channel DAC on the STX104. The base port addresses for the devices may be configured via the "base" module parameter array.
