Comment on Arduino bootloader for ATmega32 by Edwin

Hi Ashok, You only need to set your USBASP in the makefile if you use makefile to program the chip (as in make program). If you know how to use USBASP with avrdude (the default programmer) you can use the makefile just to compile the hex for the bootloader - and leave the programming to another tool. Even AVRstudio can be used for that.

After compiling using the makefile, the hex file should be programmed first. After that, the mega32 can be programmed using the same serial protocols as for example Arduino is using.

Since in Arduino also an option / structure is included in newer versions to have your own hardware descriptions, I’ll really have to look into an easy way of testing mega32 support for arduino. In fact the controller architecture is similar to the still supported ATmega8.

The pin-mapping should be included or inserted in your arduino environment. This file tells arduino when you use digitalwrite(1,HIGH) which of the hardware pins you have named 1 …

Hmm.. difficult. I bought eight of them two years ago in a webshop - apparently they had got ‘dumped’ on the market. I haven’t been able to find them ever since (at least not in a shop) but now and then they pop up on ebay or other second hand market places. I’m also still out looking for more- from a robot-parts-scavenger point of view they are excellent value for money.

Hi. I was looking for the cleaning robot and I find nothing. Where you say that you can find it for less than 30 €.
Thanks

Dear Edwin,

First of all your page seems to give confidence and a ray of hope to burn the ATmega32 with Arduino framework. As mentioned by you I have some difficulties in understanding certain steps. I wish to know

* I have an USBASP programmer and understand that the makefile needs to be changed with usbasp and the port as usb. Am I rite?

* Now after compiling using the makefile you had provided I have to burn the hex file to the flash of my ATmega32 rite?

* Also the part that is not very clear is the one where you have mentioned about the pin mapping. Should I replace the files in my Arduino software directory with these file you have provided?

Please help me on this.

Thanks and Regards,

Ashok Srinivasan.

Hi Edwin,

Great Idea. This is just what I was looking for. Did you finally get to progress it. If Yes … Pleeeeeease sen me the details. I’m working on something similar and with your efforts I won’t have to reinvent the wheel

I did use the furbies original H-bridge. Ofcouse you could use your own (like an L293 chip) but the one installed works fine (obviously)

I think I answered you offline (trough mail). You can use a camera to check whether the LED is blinking codes. Might be you are using a bad LED, an incorrect series resistor (use 100R or 220R or something in that range). Is your board powered trough USB or an external source?
