canable2 gs_usb SetCAN baudRate

[monkeyish-smart]

hello, I had some problems using MKS CANable V2.0。
1.about"BUSMASTER_Installer_Ver_3.2.2-cantact", I set baudRate 500k test normal，but set 100k Software crash。The supported baud rate types are not complete, Is there any plan to open source busmaster_installer_ver_3.2.2-contact?

2. about baudRate，BUSMASTER send 00 0b 08 01 11，but theoretical calculating value：170000000/((17+1）*(1+8+11))=472,222k，Wide margin of error.Maybe I'm not understanding this right.
   I know that this can be delivered by libusb_control_transfer 0x41 0x01 command with the following structure。Can you provide a range for correctly setting the baudRate value? eg, phase_seg2？ and phase_seg1 and so on，
   typedef struct {
   unsigned int prop_seg;
   unsigned int phase_seg1;
   unsigned int phase_seg2; //1~16？
   unsigned int sjw;
   unsigned int brp;
   }GSCANDeviceBitTiming;

I got it wrong 170000000/((17）*(1+8+11))=500k，but 800kbps is difficult to calculate for 170M main frequency. "BUSMASTER_Installer_Ver_3.2.2-cantact" is right，but 125k or 100k Software crash，These baud rates are commonly used。

Same here. CandleLight not usable with Windows. Device doesnt install drivers automatically, need to install manually WinUSB, after cangaroo not working with device, and BUSMASTER crash after speed change different then 500000.

The Candlelight firmware from MKS Makerbase is crap.
No driver is installed on Windows and it does not implement CAN FD.
Also using 170 MHz clock is not intelligent at all.

As all Candlelight projects on Github are incomplete or do not support the STM32G431 I had to write a completely new firmware 2.5 for the MKS Makerbase:

You can now use HUD ECU Hacker which automatically calculates Prescaler, Segment 1 and Segment 2 for any baudrate / samplepoint combination that you enter. It has a complex algorithm that even matches the nominal baudrate with the data baudrate so you don't get phase shifts at the moment of baudrate switching.

You simply enter the values that you need and all the calculation is done automatically:
