There is a note for UFQFPN32 package, that says "There is an exposed die pad on the underside of the UFQFPN package.", But there is no similar statement for UFQFPN28 package for the same device. Is it intentional or missed or if there is any plan to ...
Hi all,I'm porting a project from a F072 (Nulceo-F072) to a custom PCB with a STM32L072.The board is going well, except when I try to use the USB (CDC mode).When I plug it into my PC, the OS can see it - Bus 006 Device 072: ID 0483:5740 STMic...
Hi all, Am using STM32L010R8T6 device how to retain gpio state when jumping from main application to bootloader section. i want to retain one gpio pin state from main application to bootloader. How to achieve it. Is there anyway to achieve it. Please...
While connecting the battery, the ground was inverted with the VCC and vice versa. As a result, this capacitor burned out. I need to know the function of this part and if I can continue to work normally after what happened.
Hi there,I recently transitioned my project from the STM32L0CBT6 chip, which has a 128KB flash size, to the STM32L072CZ variant with 192KB of flash memory. As I progressed with my project, the only modification I made was adjusting the flash memory r...
Hi,i'm using a STM32L031. In my code i first initialize the MCU (FLASH, CLOCK, INTERRUPTs, GPIOs), start the LPTIM (running on LSI), then slow down the MSI clock, start the timer22 for PWM and go into low-power sleep mode. When i let the program run...
Hello, I am working with my custom PCB with STM32L053R8T6. My code works just fine when I run it in debug without any stop mode (deep sleep). It enters to the RTC and button interrupts perfectly. However, when I want to make the MCU enter to sleep mo...
Hello Community,Reaching out to you for feedback on the attached configuration for Vcc on my new STM32 based DAQ board.My objective was to reduce the inductance to the Vcc pins of the MCU (STM32G0B0RET6 64 LQFP package). Hence I clubbed three pins:A)...
I'm developing a vibration and temperature analysis system.To do this, I have developed a sensor based on an STM32L053C8 chip and a KX122-1037 accelerometer.Looking at the datasheet, this accelerometer can reach a maximum data rate of 25600Hz, which ...
Hi all, for a projet I need to create a signal at 500khz, and every 60 µs I want to stop the toggle (or not) I generate the signal with the output compare of tim2 (on stm32L073)then, in TIM2_IRQHandler(void)I try to count the number of call, then st...
