The 24V car battery is powered by a step-down chip to 5V. What is the lowest input voltage of this (DC/DC or LDO) step-down chip? Is it 35V or 40V? Thank you....
I switched from STM32F103 to STM32L152. Now I want to drive the segment LCD but it can't light up. I want relevant information or examples! Or guide me. Thank you! !...
I hope that the FSMC of the 103VE system can work in a non-multiplexed mode to expand two DAC chips. If the NE1 signal is used to select the device, the logic circuit must be increased. Can A23 and A2...
