The external RTC clock of stm32f765igt6 chip,the waveform of the clock is very small,RTC clock is very inaccurate.This is whether the crystal oscillator or capacitor selection problem, or our single-chip RTC drive problem;

For the external RTC clock of stm32f765igt6 chip, we use a 32.768KHz crystal oscillator of Epson, which is equipped with 10PF capacitor. Some of them will make the MCU unable to start, and reduce the capacitance value to 2pF, MCU can start, but we ac...
