Re: Bricked by custom app - how to recover?

Hi jenkie2,

Welcome to the club. I have started code attempts at Nunchuk and frozen the STM for a USB download.
Also, an attempt to achieve the STM by the STM-linker v2 was not possible. Last Hope is a programming attempt by JTAG.

Re: Nunchuk nRF <-> VESC HW 4.7

i found this Post from Benjamin: CE -> Tied to VCC CSN -> The servo input (you have to remove the lowpass filter on the servo input) C3 SCK -> The ADC_EXT pin MOSI -> The SDA pin MISO -> The SCL pin IRQ -> not connected VCC -> VCC GND -> GND Pinout nRF <-> P3 P1- 3.3V <-> P5 3.3V P2- GND <-> P4 GND ...

Nunchuk nRF <-> VESC HW 4.7

Hi,
I need help when connecting the receiver to the nRF VESC with hardware revision 4.7.

Re: MadCatz Nunchuk solution

I am sorry, is this code a complete file or do i need to add it in any specific file? Does it work with the MadCatz Nunchuk? This file is for an Teensy 3.1 Mircocontroller, not for ST! This additional line is needed for MadCatz // crypto key data address Nunchuk::_sendByte(0x40, 0x00); Ask Benjamin...

Re: VESC HW Redesign (VESC Mini?)

Ok.
but 40V? But you have alternative up to 60V for 12S usage?

No chance to use KiCad? Nobody can use Altium for free. KiCad is easy to learn and the manual semi manual routing is very helpful.

Re: VESC HW Redesign (VESC Mini?)

Hi Andreas,

please take a look to this MOSFETs:


60V, 1.1mOhm, 140A, 71nC, Coolable.

DRV Fault GVDD

Hi Benjamin,

i have seen your C18 workaround for GVDD fault.

It is right:
8.2.2.1 Gate Drive Average Current Load
GVDD max I = 30mA

FOC
6 x 236nC x 30kHz = 42.5mA > 30mA!

don't solder an additional C18, put the FOC frequency from 30kHz to 20kHz (28.32mA).
