I have on my desk an STM32F407 Discovery board and an STM32U083 Nucleo board. My intent is to write software for the F407 to bootload the U083 via I2C. As far as I can tell, these are the general steps:Drive BOOT0 high and pulse the NRST pin on the...
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. ...
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...
We are using the part STM32U585 controller in our board and we have designed it with battery backup support of 3.0v We are evaluating the backup ram (address 0x50036400)performance and found that it is not able to retain the information on power down...
I am using an STM32 Nucleo-64 F401RE6 and need to interface with a sensor that has a single physical USB port but appears as two Virtual COM ports on a PC. I have configured the Nucleo board in USB_OTG Host Only mode and successfully enumerated the d...
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 ...
Hello,I am new with STM32. We would like to do a current control exactly like on this document :https://www.st.com/resource/en/product_training/STM32G0-Analog-Comparators-COMP.pdfpage 13But we would like to use COMP1 for ZCD and COMP2 for overcurrent...
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...
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...
Good day,I'm experiencing an unexplained bus fault when the MCU writes to unaligned (not aligned to 32-bit) addresses in the OSPI memory region. I've written a minimal implementation that shows where the issue occurs. See below.I'm using the STM32U58...
