Type of switching characteristic:

Switching CharacteristicCommon AvailableDescription
ON-OFF*This is a ST switch. Switch to one side will make the connection. Switching to the other side is an open connection.
(ON)-OFF*This is a ST switch. Switching the switch to ON will make the connection. Release it, the switch will automatically spring back to the off position. This is also known as a momentary switch.
ON-(OFF)ST switch similar to a “(ON)-OFF” except that the default is at the “ON” position. Momentary OFF.
ON-ONThis is a DT switch.
ON-(ON)This is a DT switch. Spring return default position to the “ON” position. Momentary on the “(ON)” position.
ON-OFF-ON*This is a 3-throw switch. Switching to either side will connect the respective switch. The switch will be “OFF” if it is switched to the middle.
ON-OFF-(ON)This is a 3-throw switch similar to “ON-OFF-ON”. One of the “ON” side is momentary.
(ON)-OFF-(ON)*This is a 3-throw switch similar to “ON-OFF-ON”. Both the “ON” side is momentary. When release, the switch is always in the middle OFF position.

Legend:

  • * means that this type of switching characteristic is commonly available in the market.
  • (..) bracket means that the switch position is momentary (will not latch or hold on to the position if you release the lever),
  • “ON” or “OFF” without a bracket means that it is a latch position,
  • “OFF” means that there is no connection mate between throw.

Switching characteristic (For switch with 2 or more throw. Typically for sliding switch.):

  • non-Shorting (typically) – contact is break first before making contact with the next contact.
  • Shorting – contact is short with the next contact, before breaking with the previous contact.

Microchip Microcontroller Selection

Microchip Microcontroller Series

Microchip microcontroller currently consist of the following series,

For simple application, 8 bit MCU is usually selected for its small footprint (size) and lower cost.

For a more complex application, 16 bit MCU is usually selected for its processing speed and the additional peripheral supported by the microcontroller series.

32 bit MCU microcontroller is usually not selected. If the application requires such a high end microcontroller, it is recommended to develop your application using a more commonly available platform like the Raspberry-Pi, beaglebone board or similar which support linux or standard operating system software.

Loading Arduino Bootloader to brand new ATMEL Microcontroller

This article is written as a guide to loading an Arduino bootloader or firmware onto a brand new ATMEL microcontroller IC chip.

When you first purchase a legitimate ATMEL ATMEGA16U2 chip, it is actually loaded with a default DFU firmware. If you did not purchase the microcontroller from the legitimate source, there might not be any firmware pre-loaded inside. In this case, you can only load the bootloader firmware using the ATMEL ICSP programmer method.

If you built the basic USB circuit using the ATMEL microcontroller and plugged it into your computer’s Windows Operating System (example Win7), you should be able to see a USB device name “ATmega16U2” under a folder libusb-win32 devices in the Win7 Device Manager.

Basic USB circuit for ATMEGA16U2

Basic USB circuit using ATMEGA16U2 microcontroller from AMTEL.Click to enlarge the basic USB ATMEGA16U2 schematic circuit.

Using the ATMEL FLIP software, you will be able to load firmware or bootloader using its default ATMEL DFU bootloader. You can download this FLIP software from ATMEL website. Or you can download here,

Uploading Arduino USB Serial Firmware via FLIP

  1. Plug the USB circuit to your computer. You should see the ATmega16U2 device in the Win7 Device Manager. This is the default DFU firmware loaded in the ATMEGA16U2 microcontroller chip. It is also known as the DFU mode.
    ATmega16U2 in Device Manager
  2. Install and execute ATMEL FLIP software.
  3. Select the microcontroller. Click “Device”>”Select…”, or use the shortcut key <Ctrl>+S. Select the microcontroller “ATMEGA16U2”.
  4. Select the communication. Click “Settings”>”Communication”>”USB”, or use the shortcut key <Ctrl>+U.
  5. A dialogue box may appear. Then click open.
  6. Download this USB serial firmware for ATMEGA16U2. For ATMEGA8U2, you can download the USB serial firmware here.
  7. Load the firmware on the FLIP software. Click “File”>”Load HEX File…”>”Arduino-usbserial-atmega16u2-Uno-Rev3.hex”
  8. Ensure the check box is checked. “Erase”, “Program” and “Verify”
    ATMEL FLIP software interface loading Arduino USB serial firmware to ATMEGA16U2
  9. Click “Run”.
  10. Once the firmware is loaded, you can unplug the USB connection and plugged it back to your computer. You should be able to see in your device manager as “Arduino Uno” under the section “Ports (COM & LPT)” instead of the previous “ATMEGA16U2” device.
    Arduino UNO ini Device Manager
  11. The ATMEGA16U2 is now loaded with the USB serial firmware which is used in a typical Arduino UNO board. Your ATMEGA16U2 microcontroller is now a USB serial (CDC) or USB to serial communication converter. The same converter IC chip used in Arduino UNO board.

Upload DFU Bootloader to brand new ATMEL USB Microcontroller

For the ATMEL microcontroller which does not have the default DFU firmware pre-load into it, you can load the following DFU hex file for the respective ATMEL microcontroller chip.

Since the microcontroller does not have a bootloader, the only way to load this DFU to the microcontroller via an ATMEL ICSP programmer. The instruction guide for the uploading of a firmware using an ICSP programmer can be found here.

Upload Arduino Bootloader into ATMEGA328P Microcontroller

For the ATMEL Microcontroller ATMEGA328P used in Arduino UNO, the Arduino bootloader can be upload using an Arduino ICSP programmer with the Arduino IDE (integrated development environment) Software.

  • Run the Arduino IDE software.
  • Select “Arduino UNO” from the Tools > Board menu.
  • Select “ArduinoISP” from Tools > Programmer (depending on the programmer that you are using)
  • Run Tools > Burn Bootloader

Now your ATMEGA328P microcontroller is loaded with the Arduino bootloader firmware.

Take Note for ATMEGA328 Microcontroller

Uploading of  bootloader for ATMEGA328 (signature ID 0x1e 0x95 0x14)  is different from ATMEGA328P (signature ID 0x1e 0x95 0x0F).

Check out the following webpage if you want to upload the bootloader to ATMEGA328.
