DualUartWR.png' alt='Atmega8 Uart Program' title='Atmega8 Uart Program' />Free AVR ATmega Xmega Bootloader with Intel hex Support and Automatic Baudrate Adjustment Autobaudchip. Atmel AVR ATmega Xmega microcontrollers with Intel hex file support and automatic baudrate adjustment The bootloader automatically adjusts at start to the hosts baudrate, so that it is not necessary to recompile the bootloader to a particular MCU clock. There exist precompiled hexfiles for different controller types and probably different UARTs, which work independently from MCU clock. PC Software. The chip. GUI is a comfortable PCWindows application with a graphical user interface for the bootloader, which simplifies flash and eeprom programming over a COM port. Similar to the precompiled bootloader hexfiles, the chip. GUI can be downloaded below for free. If you want to use the PC software for a customer project, we can build a customized version for you your company logo and name instead of chip. Please contact us in case this is of interest for you. Mac OS X Software. For Mac users a native Mac OS X user interface application is available at www. The page currently is available in german only, but the download link can be found easily and the actual application is in english. Thanks to Steffen Fuchs for programming this great application Linux Software. A nice command line frontend for Linux users was contributed by Torsten Martinsen and can be downloaded at https github.

DIY Soldering Station 6 Steps with PicturesCHECKING PARTSThis is a very important step, so please read this section carefully. First of all, there are many clones of HAKKO 9. HAKKO irons with A1. A1. 32. 2 ceramic heater. Cheap 2 3 clones are an early examples of non genuine parts. They use a K type thermocouple and very crappy ceramic heater or simple nichrome coil. More expensive 6. HAKKO 9. 07. The only way you can distinguish clone from an original is by markings on the wire insulation or possible absence of HAKKO brand and model number on ceramic heater itself. I was really lucky and got this one. You can check whether your part is genuine by measuring the resistance between pins or heating element wiring ORIGINAL OR GOOD CLONE Heater 3 4. Ohm. Thermistor 5. Ohm at room temperature. Tip to ESD pin lt 2. Ohm. EVIL CLONES Heater 0 2. Ohm for Nichrome heating, 1. Ohm for crappy ceramic. Thermocouple 0 1. Ohm. Tip to ESD lt 2. Ohm. NOTE If your heating element resistance is very high, it is most likely damaged. You should ask for replacementif possible, or purchase a new genuine A1. POWERTo make things a bit confusing I have drawn my transformer as two transformers. The circuitry itself is very easy and you should have no problems understanding it. At the output of each secondary we will put a rectifier bridge. I bought a few small 1. V 2. A bridges, which should be good enough. The transformer itself only outputs 2. A max on 2. 4V line and the iron is rated at 5. W, so our theoretical max power is going to be around 4. W. 2 2. 4V DC output also has a smoothing 3. V 2. 20. 0u. F capacitor. This might be an overkill, but in the future we will probably connect some more stuff to 2. V line besides ceramic heater. Ive used an LM7. T voltage regulator with some capacitors to drop 9. VDC to 5. VDC to power up the control board with all logic components. PWM CONTROLThe second schematic demonstrates how we are going to control our ceramic heater we acquire the PWM signal from ATMega microcontroller and send it through PC8. IRF5. 40 mosfet. Resistor values at this stage are purely theoretical approximations and may be adjusted in the final design. Pins 1 and 2 correspond to ceramic heater wires. Pins 4 and 5 thermistor wired to the output connector, which we will use as inputs of LM3. Pin 3 is an ESD connection from the soldering iron. CONTROL BOARDAt the heart of my design is an ATMega. This is actually the first time I work with something other than ATTiny. ATTiny. 23. 13. This MCU gives us enough IO pins to avoid using shift registers for IO and simplify our design. Three OC pins will provide enough PWM channels for future upgrades secondary iron for example, while tons of available ADC channels can provide additional temperature monitoring capabilities. As youve probably noticed, Ive already added an extra PWM channel and an extra temperature sensor connectors for future add ons. At the top right corner we have our rotary encoder connections A and B for direction, plus the push button. LCD connector has been separated into 2 parts 8 pin Supply and Data, 4 pin contrastbacklight control. In addition to essential connectors Ive added 4 pin UART for preliminary debugging well only use RX,TX and GND pins. ISP connector is not implemented. We will use a DIP 2. R4 and R8 control the gain of corresponding amplifier circuits x. Some things may change in the final design, but overall structure stays the same.
