C headers for AVR microcontrollers. Arduino must die!

AVRC

Library for AVR microcontrollers' programming.

Classes helps you to write AVR microcontrollers' code on programmer-friendly laguage :)

All code wrote in .h headers files, so .HEX size has minimal difference with plain C-code. You can easly use this library with any other libraries.

Library grants easy access to:

• UART, SPI, hardware I2C (TWI), software I2C
• LED manipulations
• Bit mathematics
• IR NEC protocol

Supported devices:

• nRF24L01+
• DS1307
• DHT11

Currently in progress: ESP8266, BMP180, BMP280

#Code sample

int main()
{
	led(DDRB, 0);

	uart_init(UART_BAUD_8MHz_38400);
	nrf24_init();
	nrf24_config(sizeof(uint8_t), 2);

	uint8_t b;
	while (1)
	{
		led_turn_on(PORTB, 0);
		nrf24_send_char('#');
		led_turn_off(PORTB, 0);
	}
}

avrc's Issues

Use TW_STATUS macro

I suggest to use TW_STATUS macro from avr-libc instead of switch (status & I2C_STATUS_MASK).
By this way your code will transform to switch (TW_STATUS)

switch (status & I2C_STATUS_MASK)
