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...
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 ...
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...
I want to make my own development board based on Stm32 but I want to have just one USB port , that when I plug it into my PC i can use something like Kiel to upload my firmware.. and not have to open up another application to up load through boot-loa...
After a view short tests with the ST Motor Profiler the Rotor seemed to stall.(Lab-powersupply 22V 9A)Then smoke appeared (not sure where exactly)Now every time i want so start the Profiler it says "Over current".Even when i set the maximum current t...
