Ask questions and find answers on STM32 hardware set-ups, including schematic-related challenges, debugging probes, power configurations, and more.
I've gone over the hardware with a multimeter and all the pins have the right continuity, I've checked the design against the Nucleo-144 L552ZET6Q schematic and it checks out so far, and I've also checked the connections to the ST-LINK/V3 pins I'm us...
I'm doing PCB layout and I'm trying to assign pins for the HyperRAM (HyperBus) that will give me the simplest layout.The app note for the RAM IC has extremely strict length matching requirements. For example, matching between the data lines all have ...
I want to develop my own PCB using STM32F4. I want to use one external clock (16 MHz). I wonder where I have to connect the clock: OSCIN32-OSCOUT32 (pins 3 and 4) or OSCIN-OSCOUT (HSE) (pins 5 and 6 in STM32F446RET).I can see in the development board...
Section 6.4.4 of RM0433 is the only place I could find that says what to do with VBAT rail when not using a battery. It says the following:If no external battery is used in the application, it is recommended to connect VBAT externally to VDD through ...
I have a DISCO F4 development boards and learning more about it. I want to build an external power supply board with a 5v regulator to power the DISCO board, while it is still connected to USB so that I can program and debug as usual. I need the exte...
For our device, we are using STM32H750 IC. in some 100 PCBs manufactured at our company, in 1 or 2 PCBs we cannot program the blank MCU and get this warning in STM32CubeProgrammer. "Warning: The core is locked up"What can be the issue? any specific p...
We have designed our own STM32L0 based board along with STM32F103CBT6 for Programming.STM32F103CBT6 is blank chip , where we will get STlinkV2 firmware files?
I have a python script in order to flash many stm32 chips each one connected with a stlink. 5 devices. My python script is designed to create threads by using threading package, and the idea is flash all the devices at the same time. But this is not ...
Are there any ST discovery boards with WiFi supporting WPA3-Personal protocol?I need WPA3 to connect to my iPhone hot spot. It seems that since iOS 15 WPA2 is no longer supported.
