AsmTinySerial

Serial assembler library for AVR ATtiny

Description

This serial library is written in assembly and is based on work done by Ralph Doncaster.

With a C interface it has been written for microcontrollers Atmel AVR Tiny and Arduino IDE.

At the end it has been tested on a ATtiny85 and must be at least compatible with ATtinyX5 series.

Library is only 260 Bytes.

Arduino installation

To install the library in the Arduino IDE steps are:

• Download AsmTinySerial-master.zip and extract it.
• Remove -master of the folder AsmTinySerial-master in order to have AsmTinySerial.
• Close your Arduino software if opened.
• Move the AsmTinySerial folder in your Arduino sketchbook/libraries directory.
• That's all, restart your Arduino software.

How to use

Library provides two functions:

• void SerialInit( uint8_t , unsigned long )

  It allows to configure transmission port thus baud rate:

  • The first parameter is the transmission port.

    Ports allowed are from PB0 to PB5.

  • The second one is the baud rate.

    Typically: 115200 Baud.

• void SerialTx( const char * )

  It allows to send a string through a character array.

AsmTinySerial_Demo
