I use non-rechargeable battery so, recharging is not possible.If I only use battery for my oscillator in low power mode, in this case do you have idea how to calculate power consumption in cube Mx for RTC power domain ?

1. I am using 25 MHz crystal from NDK, exact part number is NX3225sa-25.000m-std-crs-2. I use 22pF capacitor with this crystal. I have attached Crystal datasheet as well.2. Power is delivered from MCU itself through its OSC_IN, OSC_OUT pins. So, what...

Please find attached short videos of LTDC Clock waveform as seen at the input on TI TFP410 HDMI IC. This signal is measured using DSO with probe up to 100MHz and sampling rate of 1Gps. Observations:External Crystal are more accurate as expected. LTDC...

External 32.768KHz Oscillator for RTC in STM32H743

External Crystal issue when STM33H7 LTDC interface used with RGB to HDMI convertor TI TFP410

STM32 CUBEMX v6.3.0 does not work with H7 firmware v1.8

STM32H7 latest firmware v1.9 has a bug which causes FATFS API to return FR_DISK_ERR.
