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

When HCLK is reduced from 48MHz to 1Mhz, the internal reference voltage is read much larger which is wrong

I'm using STM32F030F4, when use 48MHz HSI, everything seems ok, and the internal voltage reference is read as 1.24v. But when reduce the HCLK from 48MHz to 1MHz, the ADC seems work abnormal, the internal voltage is read as 1.41V. I tried different HC...

STM32F103RB DMA issue.

Hi all,I'm using SPI to communicate with an Adafruit 2.8" TFT LCD, (ILI9341 based). This is mostly working fine, I can plot pixels, draw lines, circles fonts etc. So the communication with the display is working. The STM end of things is a Nucleo 64 ...

STM32 FSMC 512x16bit SRAM address mapping

hi, i've some questions regarding the use of 16 bit SRAM with FSMC using AN2784 section 3.3 on SRAM https://www.st.com/content/ccc/resource/technical/document/application_note/27/bf/f5/e8/d7/82/44/6f/CD00200423.pdf/files/CD00200423.pdf/jcr:content/tr...
