Ready-to-use servo system brushless solution based on STSPIN32F0A, mainly used in robotics and automation

EVALKIT-ROBOT-1

Overview

The EVALKIT-ROBOT-1 is an evaluation kit offering a ready-to-use servo brushless solution.

Thanks to the high integration level of the STSPIN32F0A, the control board provides a powerful power stage, the analog circuitry implementing current sensing and overcurrent protection and a Cortex-M0 microcontroller performing a Field-Oriented Control with closed-loop positioning. All packed into a 40 mm x 40 mm footprint.
The maxon EC-i 40 motor, thanks to the optimized magnetic circuit, offers a very high torque density and very low cogging torque. In combination with the maxon ENX 16 EASY 1024 pulses incremental encoder, it is an excellent choice for reliable, robust and high-precision position and speed control.

How to configure stm32f103vct6 serial port UART4 and UART5?
[i=s]This post was last edited by Wang Zhao on 2017-2-9 15:09[/i] The asynchronous serial ports UART4 and UART5 of stm32f103vct6 can only send data but not receive data with the following configuratio
Help: 51 and 8155 connection problem, analog port method
As the title says, since 8155 only needs the lower eight bits of address, P2 is reserved for other uses, so I want to use common IO to simulate the address bus, ALE, WR and other ports. I wrote the pr
