"Hacked" an old hard drive brushless motor running at 4500RPM without using the rate control circuitry. All operations are implemented by STM32F407VGT6.
One day, I saw the prototype of the abs function:
int abs(int n)
{return n0?-n:n;
}It’s that simple, hahaha. If you haven’t seen it, you might not think it’s so simple, or you have never thought about
1. Reasons for debugging:
The project requires four CAN channels, but the MCU used is STM32F105, which only has two channels.
CAN, so we use the Microchip SPI to CAN chip - MCP2517. During the debuggi
I have a question for you all. I made a 4-layer board with blind via inner 2 - TOP, but the exported Gerber file shows BOTT-TOP, and both are connected to Bott's GND. What's going on?
According to the LVDS principle, when a differential signal needs to be sent, an LVDS differential signal transmitter should be used. The LVDS output differential signal should have two paths, IN+ and
