This constructor is used to open an interface to an AD420 via the provided SPI interface.
| [in] | apSpi | - Pointer to the SPI interface for the DAC8534. |
| [in] | apLatch | - Pointer to an output latch (default:NULL) |
| [in] | anLatchID | - ID of the latch to use for this device, if any |
| tcDspDacAd420::~tcDspDacAd420 | ( | ) |
| bool tcDspDacAd420::update | ( | unsigned short | anData | ) |
Updates the AD420 with the provided 16-bit data.
The data is loaded to the DAC output immediately.
| [in] | anData | - 16-bit data to load to specified DAC channel. |
tcDspSpi* MityDSP::tcDspDacAd420::mpSpi [protected] |
Access to the SPI bus.
tcDspOutputLatch* MityDSP::tcDspDacAd420::mpLatch [protected] |
Access to latch selector.
unsigned int MityDSP::tcDspDacAd420::mnLatchID [protected] |
ID of latch to use (if any).
unsigned short MityDSP::tcDspDacAd420::mnLastData [protected] |
Last data written to DAC.
