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...

STM32F407 FPU clock cycles

I have been testing the performance of some maths functions on an STM32F407 CPU running at 168 MHz. From the documentation it is stated that the vmul.f32 (HW 32bit multiply instruction) should take 1 clock cycle to operate. Using my simple test progr...

How can i get SD Card connect and disconnect interrupts

Hello All, I want to get an interrupt whenever i connect or disconnect sd card in to sd card slot . How to do this ?I have stm32f7 discovery board . I searched in hal_sdio.c , but couldnt get any info. what is the best way to achieve this ? Thank you...
