Tools for Programming User Interfaces for STM32 MCUs

Hello everyone, actually im working with the STM32 Microcontrollers and I wish to program a User Interface that can connect to my board via UART. My question is : Which tool is recommended for programming User Interfaces under STM32? Thanks for any p...

Vbat measurement way off (0.15V)

I use the Vbat pin to measure a lithium battery (3.6V) at a STM32L471 (Vcc=1.8V Vdda=3V).However my measurements are off by ~0.15V even though I confirmed the physical signals.Do I have to calibrate the ADC somehow for this to work properly?Expected ...

hi sir, i am using STM32L432KCU6 controller .jtag is detecting but while flashing it is showing error as "could not enter into debug mode".i have connected 10K to BOOT0 pin.what can be the issue?

Doubts about ADC differential mode in STM32L41x up to STM32L46x

Hello,both datasheets and rm0394 rev 4 talk about "­ Manage single-ended or differential inputs" and Figure 39. : ADC block diagram show ADC_INP[16:1] and ADC_INN[16:1] . However Pinout tables in chapter 4 : Pinouts and pin description only shows ADC...

stm32L151 RTC AlarmA does not work

We have tried to set an rtc alarm interruption but it does not work. We can see in ​debuuger in the system viewer that the alarm has been configured. But when it comes to see the alarm interruption we see that it does not occur.See bellow the code fo...

STM32L471ZGT don't wake-up from standby and shutdown modes at ambient temperatures below -10..15C.

Hello. I want to use STM32L471ZGT to write a rare signal to flash. All the rest of the time it should consume as little as possible. I config RTC for alarm (and then try wakeup), all working perfectly if ambient temperatures -10C and above. But proce...

STM32l152 can't handle load transient response?

Im using a STM32L152RDT6 in my design and a regulator TPS78326 which does the power supply to the STM. If waking up from STANDBY, the load transient response causes a drop of Vin. In this case 2.6V to 2.4V. The STM is supposed to work down to 1.8V, s...

Why file transfer speed of USB HS MSC example code is very slow?

I am doing a project using STM32H753 controller. When I flash USB HS MSC example code and transfer files , speed is very slow. It seems no difference between FS and HS modes. A large compressed files ​do not get transferred. Please help.

How to program internal flash memory of STM32H753 Controller

I am having problem with writing program to internal flash memory. How to read from flash and write to flash? ​How to compare flash contents with uint8_t array contents? How to write uint8_t array contents to flash memory ? Please help
