Crate dac_lib_mcp4725 

MCP4725 Driver

Provides a unit tested driver to access the MCP4725 digital to analog converter ICs.

Focuses on:

• Providing reliable data.
• A safter interface to an i2c DAC.
• No infinite loops.

 use dac_lib_mcp4725::MCP4725;

 /*--SNIP--*/

 fn main() -> ! {
     /*--SNIP--*/

     //Device Specific I2C pins(ch32v203kxt6)
     let scl = p.PB6;
     let sda = p.PB7;

     let i2c_config = hal::Config::default();
     let i2c = I2c::new_blocking(p.I2C1, scl, sda, Hertz::hz(100_000), Default::default());

     let mut dac_0 = MCP4725::new(&mut i2c, DEFAULT_ADDR);

     //Set the output to full VCC.
     let ret = dac_0.write_dac(0x0FFF);

     if !res.is_ok() {
         //TOSS ERROR MSG
     }

 }

Structs

DacRead

Reflects the data from the DAC when preforming Read operations.

MCP4725

Enums

Command

Command bitmasks, see datasheet page 18/19 for details

FPowerModes

FPowerModes are for when writing using Fast mode. It affects bits 4 and 5

PowerModes

PowerModes are for when writing using normal mode. It affects bits 1 and 2

Constants

DEFAULT_ADDR

The default address, depends on factory programming and the configuration via the address pin.

JUMPER_ADDR

The address for jumpered units
