pf26 said:Hi, Thks a lot for these updates !
Could you please tell where we can get the new firmware versions 1.5 or 1.6 (.bin files) which seem to be required. I am not familiar with Github, and I prefer not buid them myself whenever possible.
Otherwise I managed to program my VESC using a STM32F0 discovery kit, which includes an STLINK-V2, and this seems to be the cheaper option.
Anyway, it all works now. Still some little mechanical issues to clear before new tests (E-bike with timing belt and large 3d printed pulley drive)
ssa said:Question about 12S and 200+kv : I have 213kv motor and I want to use 12S (currently I have 6S). Will it be safe if i don't go at maximum speed (which is 50kph, i will hardly go faster then 35kph) and/or set max ERPM limit to 80000?
Why 12s and not 10s : there is a cheap 6S on HK compared to 4S with same capacity. So just a question of money, 10S voltage would be enough for me.
Jacob, for now it only works with the Kama receiver?jacobbloy said:I would say that we could design a receiver to go with it!

chuttney1 said:This is just a little notice to anyone updating their VESC to latest firmware version 1.7. I have made the update a few minute ago with encountering an error and a possible solution. First off my version of Ubuntu I use is 14.10 but methods here apply to any version of Ubuntu 14.XX and maybe Ubuntu 15.XX given a new update by Terry Guo's "eabi" file. I use the usual "sudo apt-get update" command to update linux. I encountered an error "Unknown module(s) in QT: serialport". Searching Google and looking for an answers is vague so I decided to delete the file and start from square one of compiling all needed files. During the process I run into an issue of the command "sudo apt-get install gcc-arm-none-eabi=4.9.3.2015q1-0trusty13". I tried with "utopic14" since Ubuntu 14.10 is utopic. Both commands no longer show the file from Terry Guo's website, but 3 updated files as being "gcc-arm-none-eabi 4.9.3.2015q2-1xxxx1". I type xxxx in the previous sentence in reference to the version of ubuntu you have. Well it solves the "QT: serialport" issue, but Im not sure exactly what specifically is update to correct the problem.
sudo apt-get install build-essential qt-sdk openocd git libudev-dev libqt5serialport5-dev
pf26 said:I am thinking of a little display add-on to the VESC, in order to show real time speed/Power/battery soc (state of charge as % of full charge). Display has to be sunlight readable and preferably use UAR, CANT or SPI connection to the VESC.
I think using sharp LS013B4DN4 could be interesting (but does not have backlight for night readability).
Maybe 4dsystems Oled would be suitable, but I am not sure they are easy to read in sunlight.
Has anyone already worked on a this ?
An alternative would be to use a smartphone and a USB connection, but mine is under Android.. and not so readable outside.
