As shown in the figure, the motor control composed of L298, the MCU is STM32F103RBT6, the power supply is 12V, and the 5V is converted by LM2676 to supply the 5V chip on the board. The 5V is output to...
The internal frequency seems to be up to 16 MHz , andthe external frequency seems to be up to 8 MHz. I originally thought it was frequency multiplication, that is, 8*8 equals 64 MHz; today I saw that ...
The modified Intel PCI-E Gigabit NIC directly DMAs to user space. After testing, it can reach Gigabit line speed. The problem is that if the CPU copies data packets from the DMA buffer to another memo...
I saw a circuit diagram of LM317, as shown below. R1 has 1.25V across its terminals, and without a battery, R1 and R2 have about 7V across their terminals. The current is about 5mA. If R3 = 1 ohm, the...
