The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on September 22, 2017 at 14:25Dear all,I'm having a problem creating a arbitrary waveform using timer 1, MCU STM32L476RG. I use STM32CubeMX (4.21.0) to generate all initialization code after which I try to start a DMA transfer from memory to ...

Hi,I have an external flash connected to STM32F722 via SPI. Is there a way to view the content of the flash? Maybe with SEGGER J-Flash program?Thanks
Hello,On a low power application, using STM32L031x, I want to monitor a 3-level signal (24V, 5V, 0V) using COMP1 and COMP2.COMP1IN+ and COMP2IN+ connected to a voltage divider with two resistors (2M-220K)COMP1IN- connected to internal VREF, so COMP...
Something I found useful and i would like to share with the STM community.The cover glass is one of the most important components of a touch sensor.Cover glass selection is all about the trade-off between the sensitivity of the touch sensor and its m...
Hello,I'm using a Murata CMWX1ZZABZ embedding a STM32L082 and the HAL v1.8.1.HAL_SPI_TransmitReceive() returns wrong LSB data :-expected : 0x33, received : 0x33 : OK-expected : 0xAA33, received : 0xAB32 : error-expected : 0x00, 0x01, 0x02, 0x03..., 0...
Hi everyone,Can I use CS43L22 just like a audio switch? In my project has a AUX input and want to switch this analog input via passthrough to the hp output. Is it possible? If yes, how? I have tried to call the following commands in main, but not get...
MCU: STM32L083UART: 9600 bp 8N1MCU freq: 32 MHzI have an issue about the internal EEPROM erase/write timing in STM32L0 MCU.I have an UART serial link configured to 9600 bauds, handled by interrupt routine in my code.Sometimes, I have to write data in...
Posted on May 31, 2018 at 03:40I am considering to use Nucleo-L432KC board and I need to use it's RTC with maintained time. User manual shows Vbat power in some internals of MCU but there is no pin to provide this power. Looks like the main chip's ...
