Generating PWM Waves Using Timers
PWM stands for Pulse Width Modulation. By controlling the duty cycle of high-frequency signals, the eye acts as a low-pass filter to control brightness. By changing t...
I want to debug the LIS25BA sensor. I don't have a level conversion chip, so I want to change the NUCLEO to 1.8V power supply.
For debugging convenience, I first changed the 3.3V LDO of ST-LINK to 1.8...
