Hi, i just added pdfs for the current hw version. The eagle files are for version 6.5.0. We once tried KiCad but we are a lot better with eagle.
If you want to try our hal implementation connect a stm32f4-discovery (we use the old version with the stm32f407 cpu but it should work on all stm32f2 - stm32f4 devices with small changes) to your Linux/OS X machine and start the term (should work under Linux). Another serial terminal will work too, but you should change term.comp as we use control chars for plotting. "?" will print the available component pins. "comp0.sink = comp1.source" will link two pins. "comp0.sink = comp0.sink" will unlink. "comp0.sink = 23.42" will unlink and set the pin. "comp0.sink" shows the value and driving pin. Nets are pins without components. Chaining pins does only work up to depth 2 (only pin0 = pin1 or pin0 = net0, net0 = pin1 will work). Currently components are fixed and you can only link and set pins at runtime. The order of calculation is fixed in the component or triggered by reading the output pin (for small comps like plus, dont build loops with these). As the software is under heavy development and we have no stable branch yet not every uploaded version will work and there will be changes of syntax and workflow in the future. On the hardware side we try to follow KISS. The main part is done by the stm32f4(even motion would fit in here) and the iramx16up60b. In the next version we will even replace the overcurrent protection with a small cpu. We are aiming for one controller board with feedback interfaces commanding three to four driver boards over a serial bus. Command in will be quadrature, can, rs485 or ethernet. The main difference to other AC drives is that wie don't use current feedback for acceleration/force controll. In future we want to try state prediction with our ac motor simulator (sim/ in the git repo, simulates all from external load over resolver noise to motor induction except pwm freqency and motor heating). But even without it we get realy good result except for motor noise (resulting from resolver noise, not present with encoder feedback) but we are working on it. Better documentation will come. But our current goal is to get our four axis robot (bosch sr60) working for 31C3. Another opensource project i know: https://www.vbesmens.de/en/upcx530-power-pcb.html (the guy lives nearby but we haven't met yet) Feel free to ask any questions or suggest new ideas. We are especially looking for better filtering and control algorithms. Nico > On 11/22/2014 05:11 AM, Marius Liebenberg wrote: >> Sounds like you are moving in the right direction with this project.
