Re: Compiling VESC firmware on Windows

egrep.exe does not exist. I have a egrep (no extension), and a grep.exe. But I think it should be launched via the shell (sh.exe does exist and it seem possible to launch "sh.exe egrep"). I think I will try EmBitz.

Re: Compiling VESC firmware on Windows

I think there is something wrong with the shell configuration in EmIDE. In general settings, there is an option saying "Shell to run commands in", and a textbox with a containing a path which in not correct but grayed out, so I cannot change it..

Re: Compiling VESC firmware on Windows

The last line of the makefile is: include $(RULESPATH)/rules.mk If I add a syntax error in this rules.mk file, then the build process shows the syntax error and stops. So I assume this file is properly used during make. This rules.mk seem to have many rules, and the one corresponding to .elf files s...

Re: FOC and ultra small angular move.

Hi, Playing with VESC FOC +encoder (8192 counts per turn), I can achieve movements of a few counts using a 11 poles BLDC. Probably, with more care and good encoder, one can control maybe 10 "electrical" degrees (need to divide this by the pole count to get real degrees out of the motor). T...

Re: Connecting 2 VESCs by CAN: Battery Current?

CAN bus is mostly used to transfer a speed reference from a master to a slave. The setup of each VESC is the same as usual, but you may configure half the maximum allowable battery current for each VESC. It is not clear what you mean by "connect 2 VESCs) I assume your configuration has one moto...

Compiling VESC firmware on Windows

Hi, I'd like to test some changes in VESC firmware, and it is easier for me to stay under Windows XP. I installed an IDE (emIDE), GCC arm toolchain and GNU make. I had to change some details in some .mk file (replace "shell cat".. by "cat") otherwise, it would generate errors. Bu...
