Motor control design based on LPC860 MCU

This LPC860-based motor control reference design includes PMSM flux direction control and BLDC motor commutation control. LPC860 utilizes flexible timers and ADC modules to provide a complete set of peripherals required for motor control, making it suitable for home appliance applications with three-phase motors or multiple DC brush motors.

The motor control reference design uses the LPCXpresso860-MAX evaluation kit and the FRDM motor control development kit, which includes the FRDM-MC-LVPMSM and FRDM-MC-BLDC driver boards to drive the motor. The controller uses a Flextimer (FTM) to generate a PWM signal and utilizes NXP's RECESL control algorithm library to trigger the ADC in an interrupt to run the motor control algorithm after the ADC sampling is completed.​

Homemade 10KV electronic load

Commercial electronic loads are more expensive, especially high-power loads such as computer power supplies that must handle transient current spikes well above their nominal ratings (1800W spike for a 600W GPU) and should be tested under worst-case conditions to Ensure stability.

Breadboard without jumpers: Based on Raspberry Pi Pico, analog switch matrix replaces jumpers

Flirting with jumper caps is a common practice on most boards, but not this board, which is designed to replace all those wires with an analog switch matrix. All one has to do is plug in the device and make a virtual connection on the accompanying GUI. There are also many built-in functions such as DAC and ADC, and the circuit can be switched under the prototype as needed. It also has some LEDs embedded in the breadboard area that light up and provide visual cues that they are connected to each other.

An open source project for underwater sensor nodes based on single-pair Ethernet technology SPE (from tutorial to actual combat, English)

Single-Pair-Ethernet technology (SPE, Single-Pair-Ethernet) describes the transmission of Ethernet through only a pair of copper cores. In addition to transmitting data through Ethernet, it can also simultaneously provide power to terminal devices through PoDL (power supply over data lines).
