VESC Firmware

Hi All,

After flashing the latest firmware 5.2 to my self developed board, I do not get a connection to the USB port.

Interesting enough the USB port comes alive only after I send a few messages over the CAN Bus.

Initially and after power off/on, the red en green light flash twice each 2 seconds. After sending the CAN messages, the green LED is lit, but very dimmed and the red LED flashes twice each second.

After this I have a "ChibiOS/RT Virtual COM Port" available and the VESC Tool connects to the drive over USB.

Hi, i have a old 4.12 vesc. The vesc works since 2017 with FW3.29.

Today i want update to 5.02. My steps below (Ubuntu 20.04 & STLinkV2:

git clone https://github.com/vedderb/bldc.git bldc-firmware

Edit conf_general.h ->
#define HW_SOURCE "hw_410.c" // Also for 4.11 and 4.12
#define HW_HEADER "hw_410.h" // Also for 4.11 and 4.12

make upload

** Programming & Verified OK **

But now i cant connect to the Controller.

Hi, my vesc flipsky 4.20 dual has 5.1 firware, all work OK. Now installed 5.2 or having problems with one of the engines, my question how can I reinstall 5.1 from my phone app, thanks

I'm curious if there's a quick way to inhibit braking with an external pulse.  I'm using a pedal torque sensor to drive ADC1 in current+braking mode on a bike.  If pedaling becomes too easy, braking kicks in.  I want to use the cadence output (which is 36 pulses/rev., currently on ADC2) to inhibit braking so that if there's forward pedal movement, even if torque/current goes to zero there will be no braking.

Hi All,

I'm playing with making a custom application for an e-bike with bottom bracket torque and speed sending. Modifying the ADC app for reading in the torque is straightforward, but I also need to repurpose a pin to use as a digital input with an interrupt to count the pulses coming in from the speed sensor. I'm using the 4.12 hardware. Can anyone give me some advice on that?

I have a relevant degree, but I haven't done much with embedded hardware since then and I've only recently started playing with the STM32Fs.

We use the Servo Out functionality for steering a R/C vehicle. Previously on the Mk3 and Mk4 we enable SERVO_OUT_ENABLE, compile and upload to the VESC6. This would enable the Servo Out functionality.

Hello,

I have made a custom HW for my e-bike project, based on HW 6.4, with some minor modifications. The PCB has a built-in NRF24L01 IC, with an external 2.4GHz / 2dBi antenna connected.

If I type "hw_status" in the VESC tool terminal in Windows, it returns ​Permanent NRF found: Yes

So it looks like the controller can communicate with the NRF24 module. My problem is that I cannot connect to the VESC with my phone via BLE (the VESC doesn't appear in the list when scanning).

Hello and merry christmas
I have a 75/300 model R2. it has software 3.62 and I have tried to upgrade.
I have seen tutoials and tried to upload newer software via computer and mobile.
What am I doing wrong?

Hello,

Does someone knows how to charge the hardware version on VESC?

I have now the hardware version 75_300 but I need the 410&411&412.

Thank you in advance for your help
