STM32 MCUs Products

The program is stuck in the highlighted code. What can I do to fix this issue. Im just trying to use a previous code to make the led blink/ stop blinking once the button is pressed.

TVREFINT Internal reference startup time - - 2-3 ms

Hi,From the data sheet of STM32L072xx it is mentioned that Tvrefint start up time is 2-3msec. When using Vrefint in comparator, does controller take 2-3msec each time to compare input with Vrefint or it is just the initial start up time?Because I hav...

STM32H7 IEEE1588v2 Clocking

Assuming that STM32H7 is configured as a clock slave with IEEE1588v2 (LAN8742A as PHY), can the received/sync'd clock signal be fed into the internal clock tree to produce 32.768MHz clock output? If so, do any signals need to be routed from one ball ...

NUCLEO-H743ZI2 SDIO interface, how to utilize SDR104 data rate?

I am using a NUCLEO-H743ZI2 to read 16-bit data in via GPIO pins and store that data to an SD Card. I would like to achieve an average write speed of 20 Mb/sec for data sets up to 10 Gbytes. I am using 4-bit wide bus and have wired an SD card holder ...

Hi, I want to take data through single GPIO port pin (no UART) and store data in to program flash memory. It is like I want to program my controller through GPIO port pin. My controller is STM32G031. Can anybody help in this regard? Thanks, kaushik

Tips for maximizing performance and minimizing latency of interrupt handlers on STM32F0/CortexM0?

Also, what is the minimum time (or instruction cycles) to begin servicing an interrupt, i.e., how long does state saving take at minimum? Where would I find this kind of performance information? I am using STM32F031G6.

STM32G0/L4/etc. ADC "CALFACT" is obviously some calibration factor, but how do you translate the 7 bits into a numerical value that multiplies the result? Reference manual does not seem to want to say.

STM32H747i-Disco Display

I have been using the MSC_Standalone example to develop code on this DISCO board. I noticed that although the example makes use of the on board display, it only uses the top half. Is there a good reason for this and is there an easy fix to use the wh...

Does STM32F427IIH7 support eMMC ?

We are using STM32F427IIH7 & we have interfaced it with ISSI IS21ES04G-JCLI eMMC using 4-bit SDIO lines. But we are not able to bring it up. Does STM32F427 support eMMC or it can support only MMC?Thanks in Advance!Krishnaprabha
