 |
|
I finally got the TWI/I2C Bootloader Programmer (TWIBootProg) uploaded here into the CVS tree. This is the application I use to program the OpenServo from my PC using the Dimax U2C-12 USB/I2C bridge hardware.
This application is an MS Visual Studio .NET 2003 project. For those not wanting to build from source code, the application binary is checked into the CVS tree here.
It should be pretty straighforward to use. Just make sure the OpenServo bootloader is active when you attempt to program. I have a power switch wired to my servos which makes it easy to enter the bootloader.
Let me know if there are any questions using this application.

Just about any PC to I2C bridge will do, but Mike's TWIBootProg doesn't support any hardware other than the Dimax. You'll have to do some extra work to get it running with one of these.
1) Parse the hex file, not that big a deal, you don't really need to support all the features of an Intel hex file to be able to get this running.
2) Rewrite the bus mastering code so that you can send the data loaded from the hex to the bootloader, one page at a time.
I was too cheap to spring for the Dimax myself and built a serial/i2c bridge using a PIC uC. I've got a bit of cleaning up to do, but I'd happily post to code for you as a starting point. The PIC code is in a ""C-like"" language and the PC side is in C#. |

| When considering I2C bridges, make sure that the I2C implementation supports clock stretching. |
