Hi, in wich compiler did you compile the assembler program of serial assembly.“Half Duplex Interrupt Driven Software UART;”I does’nt see any interupt handler, what does it mean in title aboveI’ve tryed it in avrstudio but it give two errors like:AVRASM: AVR macro assembler 2.1.42 (build 1796 Sep 15 2009 10:48:36)Copyright (C) 1995-2009 ATMEL CorporationD:SerialUarteXamplesSerialUart.asm(9): error: Cannot find include file: avr/io.hD:SerialUarteXamplesSerialUart.asm(24): error: Invalid directive: ‘.extern’Assembly failed, 2 errors, 0 warningsgrtzPeter.

What is a Bootloader?Microcontrollers require a to install firmware on them. A programmer is a device, that when combined with software, loads firmware to the microcontroller. There are many programmers available. I won't go into to detail about them, but I will say that if you intend to do more than just tinker with microcontrollers, you will want to invest in a programmer.The Arduino IDE allows firmware to be loaded directly through a serial port by communicating to a piece of software already loaded on the microcontroller. This special software preloaded to the microcontroller is called a bootloader.For more information, see the article ' '.

ATtiny85 MicrocontrollerIt is a good idea to have a basic understanding of the ATtiny85 microcontroller. In addition, there are many other ATtiny microcontrollers with varying features. Change the name of the BoardIf you do not like the name of the board in the IDE (you are probably not using Snap Circuits), the name can be changed manually to anything you like. If you do not want to invest the money in one of these, it is possible to use another Arduino, such as the Uno, to program the microcontroller. Here are a couple of very useful resources that show how to do this. on Hackster.io.If you have a programmer, place the ATtiny85 into the programmer and connect it to the USB port on your computer. Open the Arduino IDE and select the Snapduino board from the Tools menu.

In the Programmer menu, under Tools, select the correct programmer. If you have the SparkFun AVR Tiny Programmer, choose USBtinyISP.

Now click Burn Bootloader from the tools menu. Pay close attention to the messages in the IDE when the process is underway. It is rare that it will fail, but it may happen. If the Arduino IDE reports that the process has failed, simply repeat it.Always make note of the clock speed that was selected when you burn the bootloader and ensure that all sketches are loaded with the same selection. If you do not use the same selection, your sketches will work but your timing will be off.

The ATtiny85 microcontroller does not have a protected-bootloader section. This means it's possible to accidentally overwrite the bootloader on these chips. If this happen, just follow the steps to reload the bootloader. Connecting the FTDI CableWe will need a way to communicate with the microcontroller form the Arduino IDE. The ATtiny85 does not have built-in USB support and we have not added this capability in our circuit. Instead we will use an FTDI Serial TTL-232 USB Cable.The FTDI cable is a USB-to- Serial cable.

It has a small microchip in the head of the cable that performs the conversion between the USB port and the Serial TTL required to program the microcontroller. This is a very poplar cable and contain be obtained from a variety of places.

The one I am using in this project was purchased from Adafruit. I like this cable because it can be used in 3V3 and 5V circuits and always supplies 5V on the power line. Most Arduino's and Arduino compatible boards have built in USB-to-Serial converters. Others have a firmware that can communicate over a USB connection. To see an ATtiny85 with a USB connection check out thePlace the ATtiny85 onto the breadboard with the 6-pin header and wire the circuit according to the diagram included in the project below.The circuit provides basic support to program the microcontroller. These components will be included in all of your circuits. The 10K Ω resistor is used as a pull-up resistor to keep the reset pin high.

The.1 µF capacitor is connected to the RTS pin on the FTDI cable to allow the Arduino IDE to automatically reset the ATtiny85 microcontroller while programming. Tune the BootloaderThe bootloader being used for the ATtiny85 requires a one-time tuning process to allow it to synchronize with the serial interface.

This step ensures that the uploading process will be consistent.Open the Arduino IDE and select the Serial Monitor from the Tools menu. When the window appears, set the baud rate from the drop down, located at the bottom right corner of the screen, to 9600 if you burned the bootloader at 8MHz, or choose 19200 if you used 16MHz.A message will appear from the device asking you to send an ' x ' slowly until the bootloader has completed the tuning process.

Simply place and ' x ' in text box at the top of the window and press send. Repeat this until the bootloader indicates it has completed. Once you have completed this step, you will not need to repeat it again unless you burn the bootloader again. Cpu = Processor menu.
