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...
