1  Using Arduino / Microcontrollers / Re: Arduino hardware with AVRStudio - coding in C or ASSEMBLY - using bootloader on: October 27, 2013, 12:01:38 am
Thanks Nick. But only recently (~2 to 3 years??) avrdude has "arduino" as programmer to assert the hardware (DTR) reset and enter bootloader. Before that it was a trick which I used "mode" command in batch file to workaround.

Just helping guys to explore more with opensource Arduino hardware. Further AVRStudio is an important part for learning Atmel products.

Best regards

Hi

It is possible to use Arduino Hardware with AVRStudio i.e. you can write your code in assembly or C Code in AVRStudio and the generated Hex file can be downloaded to your Arduino UNO or Arduino Mega using the bootloader and without the need of any hardware (AVR ISP etc). The details are as given in the following link.

Hi

Update:-

The test are ok with all voltages and current within the design specs. The documentation preparation is under way.

We are planning to sell 10 units at 27USD each. Please let us know if you need one. Kindly contact us with application details if you need any advice on design.

Thanks

Hi

I have been using Arduino and various Atmel AVR uC for many years. Though the software part has very wide user group and is well supported, hardware design gets frustrating sometimes.To overcome some frustration, I have made a flexible Arduino compatible I/O board with 8 I/O. Yes you can configure any combination among the eight I/O unlike the fixed ones found in PLC. To convert an output to input you have to remove the Optocoupler (4 pin) and flip the pins backwards and re-insert it. If no one has done it before I will call it flipOpto design.Further the I/O has different single connection for Input and output. Nothing else is needed  on low voltage side. The Output is open collector and same way Input has to be open collector.




The Arduino area is preserved to receive most of the shield. An example with Zigbee shield



The Board is without any issue other than I have decided to go for N channel mosfet intead of Bipolar Transistor, hence have to flip it on the screen print.



It also features area for a analog voltage divider so that you can get 2x high voltage in. It has big resistor space for through hole resistors.

Any Arduino I/O can be connected to any Board I/O, hence you have all the freedom.

Though I have designed it for my use (in end product)  but I have couple of PCB ready with me and I will go for more if accepted. I can offer the PCB or completed board (without testing).

Please also let me have your view on this.

Hi

I am P Sharma from AVMICROTECH New Delhi. We are in the embedded business for the last few years. We sell development boards for Atmel microcontrollers like Atmega32U4, Atmega1284 and Atmega328 and also other Robotics product like motor drivers, LCD interface boards, Xbee interface boards etc...
 
We have used Arduino for many Industrial projects due to  shorter development cycle and custom libraries. Arduino is simple for beginners but it carries all the power for complex application. In a recent application, using precision external voltage reference and putting processor to sleep during ADC, we were able to achieve very stable measurements.  We have used them in numerous applications running 24x7 and yet to see a single faulty unit back.

Thanks
