Hi,
have a question, i don't understand the difference in holding register from low register (address 0) and high register(address 1). I used QmodBus 0.2.1 and if i set degree in low register i have no problem.. But in a High register if set a value >0 the motor start with casual rpm..
Second question, i want generate the FW binary.. i Used MCworkbench and set in speed mode. Push on Generate but i have no binary but only the project. Can you help me pls?
Thx

Hi @DBrag.1 ,
The holding registers at addresses 0 and 1 set target position. The firmware manage target position in 32bit format, but MODBUS's holding registers are 16 bit only, so register#0 sets LS bytes and register#1 sets the MS ones.
Your issue could be due to the relation between final position and motion duration: the far the final position, the longer should be the time (register#2).
About your second point: the motor control SDK generates a project targeting the IDE you selected (IAR Embedded Workbench, ARM/Keil uVision or STM32CubeIDE). In order to generate the binary you need to open the project and compile it.
If you do not have an IDE already installed, I can suggest you to download and install the STM32CubeIDE from st.com. No license is required.
Please note that you need a compatible SWD programmer/debugger to download the compiled firmware into the STSPIN32F0 (e.g. STLINK-V2 or STLINK-V3)

OK thank you very much. I think there is another problem, because if motor absorption is major than 0.7A it stops working. I Have an STLINK-V3.
So i have two Kit Robot and the second i want to use it in speed mode. I generated the binary with parameter "speed" and i put in second board but i can't connect and check it with MCworkbench. I set a baudarate to 9600 and change the connections like in image.

If you want to bypass the RS485 transceiver and use the STLINK-V3 VirtualCOM instead, you need to check the following:

Hi,
i followed your check point, but device doesn't connect with MCWB. My connection and parameter setted on MCWB:

Hi,
I notice only now that you connected the TX line to wrong test point, sorry for that.
TX is on TP14, but you connected it on TP15:
Let me know if this solve your issue

Perfect! It working : )

Hi,
i would like use the speed mode FW with modbus, it is possible? For to do this i should change code or i can put the parameter (rpm) in a specific register?

Hi @DBrag.1
Glad to read the board works now.
For this new question, could you please open a new post?
