STM32U575 Boot up power consumption
Hi All, I am trying to reduce the boot up power consumption using STM32U575RIT6xQ . I using a 4-20mA power source and the boot up power is 7.6mA. After it boots up the power consumption is 3.4mA. We are using Free RTOS. Below is the pins that are act...
It is not possible to set RTC output on Tamper pin for Second and Alarm Pulse.
Hi, I try the whole day with an F103C8 to have the Alarm Pulse on Tamper Pin C13 but it is not possible, I tried with PullUp resistor and also I tried to configure manually the GPIO Pin to AF OD config. But with my Osciloscope I cannot see anything. ...
Resolved! Typo in STM32C0 reference manual?
On page 1017, Section 31.3 in Package data register of the STM32C0 reference manual (Revision 5), looking at the PKG[3:0] bitfield, when the condition is STM32C071xx, there seems to be two parameters with the same value? Was the value 0b1100 intended...

I am trying to use the Nucleo H563ZI to read a 24 bit data via the SAI with the TDM protocol. SAI has been configured in asynchronous slave mode. Valid data from the master is available after the falling edge of the FS signal. However, while calling ...
Resolved! Two VREF+ pins on STM32G474Q?
When I first glanced through the STM32G474 datasheet, I saw VREF+ and VREF- on pins 43 and 44 on the LQFP128 package. "Cool", I thought, although I had no significant need for an actual VREF- pin.However, when I was making a schematics symbol, I noti...
Resolved! code gets stuck on SystemClock_Config() or HAL_Delay() when using External clock
When ever I configure HSE in my ioc file for my custom PCB my code stops at SystemClock_Config() or HAL_Delay(). One time when I replaced 48Mhz crystal oscillator with 32 Mhz my LVCU code worked on HSE but it was considerably slow than HSI even on 1...
