H723ZG Nucleo ADC clock/noise question

After assembling the X3 external 25MHz crystal and 2 caps and generating initialize code for 550MHz clock with CubeMX my NUCLEO-H723ZG board runs fine, except ADC. It is very noisy. The CubeMX configured the clock for ADC = 96.000671 MHz (PLL2P). In ...

STM32L071RB RX Halt Issues

Hi, We have been experiencing severe issues with RX UART on STM32L071.The RX bus stops receiving data while running, and the only way we could recover from it was to initiate the UART back again which probably clears the registers.Is anyone familiar ...

Wich is the STM32F429 PLLN maximum frequency?

User' manual says that the maximum PLLN or VCO output frequency should be between 100 and 432 MHz (pg. 227). However, I was trying to set the PLL clock and the SysClock to 180 MHz and also respect the 48 MHz clocks.One possible solution is to set the...

STM32L073 PC13 settings are affecting the LSE oscillation.

We are using STM32L073.When a 512Hz square wave is output to PC1 using LPTIM_OUT (source clock LSE), if the calibration output of PC13 is set to 512Hz, the PC1 output will make a large transition to about 509Hz at around -30 ° C. When set to NONE, th...
