The debug script reads out that a register is 1 after power-on. This section of code is generated by a for loop. The initial values of the other registers are normal and there is no problem with the t...
Embedded systems inevitably have to deal with chip registers, and register operations require bit operations.
I won’t talk about the basic operations such as clearing a bit and setting a bit, but let’...
I have used protel 99 and AD 17, and I have been drawing low-speed PCBs. Although I have been in the industry for many years, I have not studied PCB knowledge in depth. Recently, I want to learn orcad...
Let us briefly discuss what is LDO.Low Dropout RegulatorA low dropout or LDO regulator is a DC linear regulator that can control the output voltage even when the input voltage provided to it is almost...
Why does I2C need a pull-up resistor? Because it is an open-drain output.Why open drain output?
The I2C protocol supports multiple master devices and multiple slave devices on one bus. If push-pull ou...
