#define BAUD_RATE   57600

Baud rate to use

The implementation is optimised for higher baudrates - please don't use anything below 57600 on an 8MHz clock. It does work at up to 250000 baud but you may experience a small amount of dropped packets at that speed.

#define LCD_SCK   PINB4

#define SOFTPWM_ENABLED

Software PWM

This enables the software PWM implementation which can generate PWM output at 100Hz on up to 4 output pins.

Definition at line 42 of file hardware.h.

#define SPWM_COUNT   3

Number of software PWM pins required

There can be up to 4 pins. For each pin you must define SPWM_PINn where n is SPWM number.

Definition at line 91 of file hardware.h.

#define SPWM_PIN0   PINB0

Pin associated with SPWM0

Definition at line 94 of file hardware.h.

#define SPWM_PIN1   PINB1

Pin associated with SPWM1

Definition at line 97 of file hardware.h.

#define SPWM_PIN2   PINB2

Pin associated with SPWM2

Definition at line 100 of file hardware.h.

#define SPWM_PIN3   PINB3

Pin associated with SPWM3

Definition at line 103 of file hardware.h.

#define SYSTICK_ENABLED

System Ticks

Enable the system ticks implementation. This allows measurement of longer periods of time (up to 11 minutes) with a 0.01 second precision.

Definition at line 35 of file hardware.h.

#define UART_BUFFER   4

Size of input buffer

Only available in interrupt driven mode. This sets the size of the receive buffer (max 256 bytes).

Definition at line 80 of file hardware.h.

#define UART_ENABLED

Software UART

This feature provides a software implementation of a UART allowing you to perform serial communications. It supports speeds of up to 250Kbps, can be configured to use a single IO pin and has an option to be interrupt driven.

Definition at line 28 of file hardware.h.

#define UART_INTERRUPT

Enable interrupt driven mode

Only valid in two pin configuration. If this is defined and you are using two pins for the UART then received data will be read and buffered as it arrives.

Definition at line 73 of file hardware.h.

#define UART_RX   PINB5

Define the pin to use for receiving

If this pin is the same as the TX pin the code for the single pin UART implementation is compiled. This means no buffering and no interrupts.

Definition at line 65 of file hardware.h.

#define UART_TX   PINB5

Define the pin to use for transmission

Definition at line 58 of file hardware.h.
