thorpej	f64c887e97	Pass the device_t into spi_configure(), and make the API contract that spi_configure() will print errors if they occur; the driver is off the hook.	2022-01-19 05:21:44 +00:00
thorpej	c86942858d	Probe / match routines should not have side-effects: do the spi_configure() calls in the attach routines.	2022-01-19 05:05:45 +00:00
rkujawa	21a43d7204	Add preliminary driver for Microchip MCP48x1 family of DACs. Needs more testing and an appropriate API for such (non-audio) DACs. For now one can set the output value using sysctl node. Also sysmon(4) will conveniently report the voltage on Vout pin of the DAC. Note that this is not an actual measured voltage, but merely calculated using equation from datasheet. Real voltage might be different and depend on analog circuitry attached to the DAC.	2014-02-25 20:09:37 +00:00

spi_configure() will print errors if they occur; the driver is off the
hook.

calls in the attach routines.

Add preliminary driver for Microchip MCP48x1 family of DACs.

Needs more testing and an appropriate API for such (non-audio) DACs. For now
one can set the output value using sysctl node. Also sysmon(4) will conveniently
report the voltage on Vout pin of the DAC. Note that this is not an actual
measured voltage, but merely calculated using equation from datasheet. Real
voltage might be different and depend on analog circuitry attached to the DAC.
