![]() DAC increments (0.4095) -> output voltage (0. End DAC module connections unsigned int value Ĭhip_Select_Direction = 0 // Set CS# pin as Output Sbit Chip_Select_Direction at TRISC0_bit Also, this example demonstrates working with Microchip's MCP4921 12-bit D/A converter.Ĭopy Code To Clipboard // DAC module connections sbit Chip_Select at RC0_bit MFRC522 Communication Arduino RFID Library for MFRC522 (SPI) Read/Write a RFID Card or Tag using the ISO/IEC 14443A/MIFARE interface. This code demonstrates using library routines for Soft_SPI communication. This routine sends one byte via the Software SPI bus. Read a byte and assign it to data_read variable // (data_send byte will be sent via SPI during the Read operation) Soft SPI must be initialized before using this function. It provides clock for the Software SPI bus, reads a byte and sends a byte. This routine performs 3 operations simultaneously. Unsigned short Soft_SPI_Read( char sdata) Software SPI module connections sbit SoftSpi_SDI at RC4_bit Must be defined before using this function.
