For a long time I have been using the following setup:two STM32H7 eval boardsone gdbserver session for each STM32, with a different portremote debugging on the two STM32I just switched from STM32CubeIDE 1.0 to 1.10.1 and now I have this weird behavio...
I have two devices I am looking to integrate with STM32 MCPUs. One is a Honeywell HG1125 IMU and the other is an WFF93 Encoder.Both devices use LVDS signalling. I don't know much about that signaling at this point, but I am taking a broad stroke fi...
I see from the schematics in datasheet UM1956 that there is a reserved CN2 connector with SWDIO and SWCLK, NRST can be found on CN3. But I do not see any jumpers to switch whether ST-LINK is used to program on-board Nucleo MCU or an external MCU like...
HelloI may have misunderstood:By cutting some SBs offand soldering on CN2 the embedded STLinkv3 can be used externally ? meaning on other targets/boards ?
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...
