Dear community, I would like to keep the RTC value when I turn off my device (which use the Murata type ABZ based on STM32L072). I know the Vbat system is not available on STM32L0 but I neet to use this MCU. So I found the application note AN4718 whi...
I'm using an ST-Nucleo H743ZI on a Macbook running 10.14.3. The virtual com port basically doesn't work. I can send a few hundred bytes to the MCU at most, and then it stops transmitting.I'm looking it at with a scope, so my actual MCU firmware is ...
As I'm now done with the development of the main firmware for my product and ready to move my design to a custom board, I thought it might be worthwhile to make a checklist of the most important things to be considered by the designer in order to avo...
Using Nucleo-F429. This makes no sense, since the firmware upgrade claims to connect to the device to do its job.
good morning, I wanted to ask a simple question.I'm drawing the schematic of a small board based on the NUCLEO-F401RE.I have a doubt about the JTAG/SWI connector, practically on various schemes I have seen that there are pullup/pulldown resistor (see...
My ST-Link was working fine with keil, but then i tried to install different tool chains like true studio, and running linux on virtual machine, st-link utility (and in the process i may have installed some new drivers). Now windows don't detect ST-l...
Looking to connect st-link-v2 debugger to my STM32F030F4P6TR chip. What pins needed to connect?
Hi i have to modify the value of some registers to unable the ETM.i'm using st link utility. I can search the address of my register but when i modify it's value i have an error, view the image.Thank you very much
Posted on April 29, 2017 at 01:54I made a board with an STM32F405RGT6V, I follow the 'getting started design guide', the datasheet and the Reference Manual plus other documentations for ADC accuracy and so on.So now I have my board with VDDA paired ...
Hi!I designed this circuit for use with STM32F469ZI. Is it correct to use USB?
