Is there a way to view content of external flash?
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
Issue on Comparators inputs on STM32L031xx
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...
[How to] 9 things to consider when selecting a cover glass for your touch sensor application
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...

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...
RTC Battery power for STM32L432 MCU and Nucleo-32 boards ?
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 ...
How to remap CAN-Pins for a STM32F042 TSSOP20 Chip
Hi,I'm going to use a STM32F042F6P in TSSOP20 - case for a application using CAN - connectivity. The low-pin-version of the STM32F042 demand to remap the CAN-pins to alternate pins.I already discovered the hint for bit 4 (PA11_PA12_RMP) of SYSCFG_CFG...
