This probably sounds stupid but I ordered Maytech’s VESC or in general a VESC without first checking that VESCs has a speed limit (ERPM) of about 100,000 (or 60,000, can’t recall the exact number). That means I can not properly run a 820kv motor (very small and very light) using VESC.
My project is not related to skateboards or drones, it is a class project and I wanted to use VESC for two reasons: 1- It has Serial pins so I can measure current , temperature and rpms and log them 2- It seems to have a nice bi-directional positional control thus I was hoping to use it in a robotic application.
I also do not need a very high speed (rather I need a high torque) but I can not use gears (project requirements) as well as low kV (means more weight) outrunners (weight requirements).
So I was hoping if anyone here can help me set this up as I am pretty confused about the motor and battery parameters. (I know this is easy stuff but when I use low amps in bldc-tool, the motor is not detected).
Also I am using FW 2.18 and not using VESC-tool because for some reasons, I am unable to update the firmware from BLDC as well as from VESC tool. Everytime I update the FW, it says it is updated but when I reconnect my VESC, the same old FW is detected in it.
I also emailed MayTech’s support who actually first gave me VESC-tool application (which I had already tried) and when I complained about firmware not being changed after update, the sent me a link to STLink which I still have to buy.
So I have two queries really:
I need to run 820kV outrunner (very slow speed) with VESC, please tell me if that is possible on 4.2 hardware with 2.18 FW
I am unable to use the TX RX pins as I have tried 3 Arduino VESC libraries and non of them seems to get any data from the TX pin, is there anything else I should do?
Thank you Arsh
