Library Description

This library provides generic functions for working with the Click board™.

Key functions:

  • void rs232_writeByte(uint8_t input) -  Writes a Single Byte.
  • uint8_t rs232_readByte() - Reads a Single Byte.
  • uint8_t ras232_byteReady() - Checks if a new byte has been received.

Examples Description

The application is composed of three sections:

  • System Initialization - Initializes UART module.
  • Application Initialization - Driver intialization.
  • Application Task - (code snippet) - Checks if new data byte has received in the RX buffer (ready for reading), and if ready than reads one byte from the RX buffer. In second case application task writes message data via UART.
void applicationTask()
{
 char tmp;
 uint8_t rdyFlag;

// RECEIVER - UART polling 

 rdyFlag = rs232_byteReady();

 if (1 == rdyFlag)
 {
 tmp = rs232_readByte();
 mikrobus_logWrite( &tmp, _LOG_BYTE );
 }

// TRANSMITER - TX each 2 sec
/*
 for (tmp = 0; tmp < 9; tmp++)
 {
 rs232_writeByte( MESSAGE_DATA[tmp] );
 mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE );
 }
 Delay_ms(2000);
*/
}

The full application code, and ready to use projects can be found on our Libstock page.

  • UART

Additional notes and information

Depending on the development board you are using, you may need USB UART click,  USB UART 2 click or another one 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.

LR 10 click

0

LR 10 Click is a compact add-on board designed for the Internet of Things (IoT) applications requiring low power consumption and long-range connectivity. This board features the Wio-E5, a LoRa wireless module from Seeed Technology. The Wio-E5 integrates the STM32WLE5JC system-level chip and the SX126X LoRa® chip alongside an Arm® Cortex® M4 MCU, ensuring ultra-low power usage and high performance. It supports multi-mode operations, including (G)FSK and LoRa®, and can operate across a frequency range of 868 to 928MHz with robust signal strength and sensitivity. These characteristics make the LR 10 Click ideal for various IoT scenarios, such as wireless sensor networks, remote meter readings, and other applications with crucial low-power, wide-area network connectivity.

ROTARY Y click

0

Rotary click carries a 15-pulse incremental rotary encoder with detents, surrounded by a ring of 16 yellow LEDs. It’s a perfect solution for adding a precision input knob to your design. The encoder outputs A and B signals (out of phase to each other); the knob also acts as a push-button which sends an interrupt to the target board MCU. The LED ring is controlled through SPI lines (CS, SCK, MISO, MOSI). Rotary click can be used with either a 3.3V or 5V power supply.

Brushless 4 click

5

Brushless 4 click is a 3 phase sensorless BLDC motor driver, which features a 180° sinusoidal drive, providing high efficiency and low acoustic noise. This type of drivers inherently provides higher torque in general, compared to classical 120° BLDC motor drivers.
