STM32MP157 is a multi-core heterogeneous processor, in which Cortex-A7 runs the Linux operating system and Cortex-M4 runs the bare metal. This course introduces how to achieve inter-core communication between Cortex-A7 and Cortex-M4.
The compilation environment of the phyBOARD-i.MX 8M Plus development board has been set up in the virtual machine. Since it is a Linux system, the Demo routine needs to be cross-compiled and downloade
I copied a circuit of an electronic scale from the Internet. There is a resistor bridge on the left side of Vin. The Vout of this amplifier circuit is transmitted to the microcontroller for processing
Over the past six months, the forum has provided me with a very powerful learning platform! Enthusiastic administrators, rich materials, and active members. Thank you!
I hope the forum will get better
I've been working on brushless DC motor control recently. I encountered a lot of problems when writing the code. I couldn't enter the interrupt program and couldn't implement the phase change problem.
Operating environment: security monitoring system (video signal control) Main equipment: computer (capture card) + camera Transmission method: video signal cable (75-5) coaxial cable Requirements: 1 V
