STM32H7 and SYSCFG_UR2/3 register

RM0433 is very short about the SYSCFG_UR registers. Most URx registers are read-only and probably provides another view at the values of the options byte. The reason to provide another view is not clear to me. However UR2 (BOOT_ADDR0) and UR3 (BOOT_...

Unstable behavior SDADC STM32F373

For a 21-channel temperature measurement tool (NTCs) I use a STM32F373 ( SDADC1 + SDADC2 + SDADC3). I replaced a temperature sensor with a fixed resistor for these tests.The behavior of the ADCs is different and reproducible after startup:Good Case: ...

STM32CubeMX & STM32L4 Library 1.12.0 ADC Problem

Is there a known problem with HAL ADC driver in the 1.12.0 L4 HAL library?I have working code using STM32L4 HAL 1.8.1 that I recently upgraded to latest Cube & HAL (4.26.1 & 1.12.0 respectively) and I have very odd behavior with the ADC after the upd...

STM32f429i-Disc1 USB-CDC PC won't see virtual com port. Any idea what to do?

Hello, I have a STM32f429i-Disc1 board and trying to run a simple usb-cdc code. I've watched many videos on youtube and looked over many examples but I couldn't make it work. board won't appear as virtual com port on device tree. I downloaded stsw-st...

Need support for promoting STM32L4 in Capacitive touch sensing applications

Posted on July 02, 2018 at 12:49Hi Friends !As discussed in my earlier post we have developed 44 Keys capacitive touch key pad with 4 layer PCB board in Matrix touch scheme between two touch TSC groups with Layer 1= top Digital track, Layer 2= shiel...

Why is STM32F072 Temperature Sensor Calibration Value TS_CAL1 higher than TS_CAL2 ?

While implementing a course temperature monitor for our custom boards I noticed, that the readout of the two calibration values shows TS_CAL1 greater than TS_CAL2:According to documents "https://www.st.com/resource/en/reference_manual/dm00031936.pdf"...

HI I'm using stm32f103zd and iwm getting after some hours hard fault How can I detect the reason and solve the problem?

Are there any sample code for CAN bus of STM32F302?

Hi All,I am using STM32CubeMX to generate the initialization code, but it does not work. Can anyone provide a working CAN bus code for STM32F302 or any other MCUs?Regards,Jiannong
