Hi,I am using STM32f429II processor. In my application I need to trigger the RTC in 1hr,2hr,3hr,4 hr intervals. So i decided to use RTC alarm A. For testing purpose, I set a 10 secs interval from the current time into alarm register. But it always tr...
According to datasheet, VREF must be <=VDDA.We use an accurate 3.3V reference voltage on VREF.VDDA is connected to VCC supplied by a LDO 3.3V with +-2% accuracy.Thus it would be possible that VREF is above VDDA by 66mV. Is that a problem?
I added a HDC1080 temperature sensor library to the project. After removed it.But I got 30 errors from stm32f103xb.hNo idea what to do. Can you please help me?Error:../Drivers/CMSIS/Device/ST/STM32F1xx/Include/stm32f103xb.h(90): error: #101: "NonMas...
i am planning to use HSE on STM32G071GB (UFQFPN28 - 28 pin package)datasheet STM32G071 on page 41 does really make it clear if HSE pins are available in small package (28pin)datasheet states:PC14: OSC32_IN, OSC_INPC15: OSC32_OUTis OSC_OUT missing in ...
Hello all,we currently do a university projects were it is necessary to add some sort of ram (SDRAM SRAM) to the STM32L476xx MCU. Currently I cant find any development kit (or application example) for the L4 serien. Does anyone have experience and c...
Hi,In input PWM mode the counter starts and counts up with the initialization of the timer and at the first edge (trigger) it gives the time taken from initialization till the first trigger (which is wrong value at the first time only) and after that...

I am look into to use X-CUBE-AUDIO spiritMP3 for encode and decode MP3 but reading the documentation I found the following:There are no differences between the demo and the commercial version except bitrate restrictions. (Same folders structure, sam...
Hello all and good day!I have been trying to trigger an ADC using TIM6 with TRGO signal in STM32F446RE board. I am unable to do it. I have used CubeMX initialization and have been trying to use the HAL libraries for developing the code. I have attach...
