Hello. I had problems with studio back when I was starting with an UNO, and was told to update to ST and it should fix it. NUCLEO-64 G431RB 42BLS02 motor with hall sensor Studio will work right very, very rarely. The bad behavior varies, sometimes it just locks up, sometimes it becomes unrespons…

[image] sgordon777: TW, what does “Pull params” mean? It seems to pull the embedded parameters into itself even if you don’t click this? It is aimed to refresh and pull again parameter configurations allowing a resynchronization between the GUI and what is currently running in your board. …

It’s just more stuff that needs to be done. Always lots more to do, this is why I am a big fan of navigating effectively at a high level to work efficiently. We can’t do everything. We gotta focus on what matters most.

@JorgeMaker explanation is probably correct i.e. the serial comms may be unstable. Are you confident that usart rx/tx is super solid? If you are using software serial or there is noise on rx/tx or too much interrupts or mcu clock settings are not quite right then rx/tx may be unstable. I was rece…

Hi @sgordon777 , As recommended by @Owen_Williams , one approach to troubleshooting the unstable behavior is to consider lowering the bit rate of your serial port configuration. Decreasing the bit rate can enhance the reliability of your serial port communications. BR

I can try lowering bitrate, but I raised it to 921600 to solve a specific problem: When the bitrate was 115200, turning on the motor.monitor() in my loop() was affecting my FOC and causing my motor to run roughly(a once per revolution thump). Raising the bitrate to 921600 completely fixed this (I di…

[image] JorgeMaker: If you are using an stunning 921600 bit rate, almost 1 Mbps, we may have discovered why you are experiencing problems using serial port communications in a noisy application prone to noise and interference, such as control engines. . I used 921600 and even 2 x faster recen…

I’m using a ST NUCLEO board (G431RB) and Arduino defaults for the platform: upload=mass_storage USB=none U(S)ART=enabled, generic serial usb speed=low/full-speed This ST platform is brand new to me so I’ve not researched any of the settings yet(want to get motors working right). The Mass storag…

[image] sgordon777: is U(S)ART a bit-banged UART? No, it’s just meaning UART, or with synchronous option USART, they are both hardware. [image] sgordon777: upload=mass_storage The Nucleo should have on-board STLink… why not use this?
