+ | ===== Simplified functional block diagram ===== | ||
+ | |||
+ | The simplified circuit diagram shown in figure 1 is a robust solution for accurately and efficiently driving proportional and two-state solenoid actuators. Applications include motion control, latches, clamps, brakes, clutches, proportional gas valves, and proportional liquid valves. The circuit provides accurate, closed-loop current control in 2-state solenoid applications, | ||

+ | ===== Arduino Interface ===== | ||
+ | |||
+ | The EVAL-CN0415-ARDZ is compatible with the EVAL-ADICUP3029 platform. Because the ADICUP3029 is an Arduino form factor compatible development board, many other equivalent Arduino form factor development board can also be used simply by writing custom code. Below is the pinout of the custom connector of the EVAL-CN0415-ARDZ eval board. | ||

+ | |||
+ | ===== Software ===== | ||
+ | |||
+ | The ADuCM3029_demo_cn0415 provides a solution for controlling and monitoring solenoid actuator current, using an EVAL-CN0415-ARDZ shield installed on an EVAL-ADICUP3029 base board. The user interface is implemented as a command line interface (CLI) through a serial UART connection. The project is created using CrossCore Embedded Studio and GNU ARM compiler. | ||
