AC Current click can measure alternating currents up to 30A and it features the MCP3201 ADC (analog to digital) converter and the MCP607 CMOS Op Amp, both from Microchip. The click is designed to run on either 3.3V or 5V power supply. It communicates with the target MCU over an SPI interface, and the AN pin on the mikroBUS line.

Library description

Key functions:

  • void accurrent_init ( ); - Click initialization setting CS to High
  • float accurrent_getmA( ); - Gets the current value of AC Current in mA
  • float accurrent_getA( ); - Gets the current value of AC Current in A

 

Example description

The application is composed of three sections:

  • System Initialization -  GPIO and SPI module initialization
  • Application Initialization - SPI driver and slick initialization
  • Application Task - (code snippet) - reading the value of current and displaying it via UART N
void applicationTask()
{
 ac_current = accurrent_getmA();
 FloatToStr(ac_current,text);
 mikrobus_logWrite("Current value: ",_LOG_TEXT);
 mikrobus_logWrite(text,_LOG_TEXT);
 mikrobus_logWrite(" mA",_LOG_LINE);
 Delay_ms(1000);
}


Other MikroElektronika libraries used in the example:

  • UART
  • SPI
  • CONVERSIONS

Additional notes and information

Depending on the development board you are using, you may need USB UART clickUSB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.

Light 2 Click

0

Light 2 Click is a compact add-on board designed for accurate and flexible light measurement in various environments. This board features the ISL76682, a high-sensitivity, light-to-digital sensor with an I2C interface from Renesas, made specifically for automotive applications. Key features include a photodiode array that closely mimics the human eye's response, an ADC for flicker rejection, and four selectable light measurement ranges via I2C, enhancing both flexibility and accuracy. With a typical power consumption of 55µA in Standard mode and two power-down modes to minimize energy use, the board is efficient and adaptable to different lighting conditions.
