 Simultaneously updating methods are useful for higher speed applications where a small delay between channel outputs will produce unwanted signals or timing issues. For example, to use the shield to drive the X-Y input of an oscilloscope to draw a circle, a delay between writing the X and the Y channels produces a ghost ‘ellipse’ drawn during the interim between the X and Y DAC updates. Simultaneously updating methods are useful for higher speed applications where a small delay between channel outputs will produce unwanted signals or timing issues.

-This is a simple but powerful library to help the user get started.  It is well documented to ease modification of the library for any individual project.  The power supply is entirely analog, and as such, needs no software to operate. However, the ADC (part number DAC8564) and DAC (part number ADS8343) are both SPI devices. Their datasheets are freely available on the manufacturer’s webpage.+This is a simple but powerful library to help the user get started.  It is well documented to ease modification of the library for any individual project.  The power supply is entirely analog, and as such, needs no software to operate.
