RS485 3 click uses SN65HVD31DR from Texas Instruments, a tri-state differential line driver and differential input line receiver. The click is intended to be used as UART to RS422/RS485 communication interface. It is suited for transmitting smaller blocks of data over long distances, using the four-wire bus, allowing for full-duplex communication.

Library description

Carries generic functions which are mostly wrappers for UART functions.

Key functions:

  • void rs485_3_writeByte(uint8_t input)  - Write Single Byte.
  • uint8_t rs485_3_readByte() - Read Single Byte.
  • uint8_t ras485_3_byteReady() - Check for new byte received

Examples Description 

The application is composed of two sections : 

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

// RECEIVER - UART polling 

 rdyFlag = rs485_3_byteReady();

 if (1 == rdyFlag)
 {
 tmp = rs485_3_readByte();
 mikrobus_logWrite( &tmp, _LOG_BYTE );
 }

// TRANSMITER - TX each 2 sec
/*
 for (tmp = 0; tmp < 9; tmp++)
 {
 rs485_3_writeByte( MESSAGE_DATA[tmp] );
 mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE );
 }
 Delay_ms(2000);
*/

}

Additional notes and information

Depending on the development board you are using, you may need USB UART click,  USB 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.

Angle 10 click

0

Angle 10 Click is a compact add-on board that detects the absolute angular position of a permanent magnet. This board features the AS5070A, a high-resolution angular position sensor with an analog output for precise absolute angle measurement from ams AG. Based on a Hall sensor technology, the AS5070A measures the orthogonal component of the flux density over a full-turn rotation and compensates for external stray magnetic fields with a robust architecture based on a 14-bit sensor array and analog front-end. Only a simple two-pole magnet rotating over the center of the AS5070A is required to measure the angle, providing an instant indication of the magnet’s angular position.
