New possibilities for the ultra-low power segment!

STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...


CTS signal on USB CDC

Posted on May 15, 2018 at 09:13Hi,I need to send the CTS status from my target hardware to the Virtual com port driver in windows, USBser.sys.I have managed to do all the other handshake signals (DTR, RTS, DCD and DSR) working except CTS. Apparently...

ST-LINK programming code to external Flash fail

Posted on May 11, 2018 at 03:48I use ST-LINK utility V4.2 to program a code to external flash, always fail.Attachment is my code. it include embedded code(start at 0x08000000) & external flash code (start at 0x90000000).Platform : STM32L496G-DISCOEx...


VREF Output for external IC

Posted on May 07, 2018 at 13:03I have a STM32L051 microcontroller and use the STM32L0Cube HAL.I read fom the manual, that the STM32L0 have a possibility to provide a stable reference voltage for external ADC/DAC/... This is the VREF(BUF). If I under...

HAL_I2C_Mem_Write_DMA() doesn't work

Posted on May 02, 2018 at 21:24Hi everyone,I have a problem regarding the i2c communication with the 1.9 release of HAL for stm32f0.I use the i2c2 peripheral of stm32f091rc microcontroller to communicate with a EEPROM.This peripheral works very well...


Posted on May 08, 2018 at 01:29Greetings,    I'm writing an application for an STM32L496, and I'm trying to use Stop2 mode to save power.  My problem is that whenever I go into Stop2 mode, the sys tick immediately wakes up the MCU, even though I hav...

Issue using BlueNRG with CubeMX

Posted on May 02, 2018 at 23:19Hi,    I am using a BlueNRG-MS connected to an STM32L4 MCU over an SPI bus.  I was able to make it work using code from the BlueNRG development kit, but I could not make it work if I generated code using CubeMX.  After...

Resolved! STM32L041F6 datasheet error

Posted on December 06, 2017 at 08:59 Hi, I think the datasheet of the STM32L041F6 states incorrect package information on page 105: These values are not correct as pin pitch can never be 3.5mm. Where should I notify this error? Kind rega...
