I have an application where it is necessary to read data from external flash to perform operations on data stored in external SRAM by using the same fmc connections. In this case the parallel interface is important as the operations are time sensitiv...
I designed a PCB that has a stm32f446RE MCU on it. All of it seems to function well, I can send and receive over three UART channels, and can receive messages over CAN Bus. However, when I try to send messages over CANbus to a separate store-bought m...
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
