Hi alli am facing a very strange problem on my project. I can write correctly my user program using ST Link Utility, but when i try to download the same in Debug mode using IAR, it doesn't work. The only difference between the two routines is that us...
I reinstalled everything from keil to the st-link utility. I reinstalled the driver en.stsw-link009 . But still the same problem. Also it's not detected by the st-link utility.So, any solutions ?
I have a question about the electronic config on my stm32H743 board.At the moment, I have a digital pin that reads a switch position:Now, I'm going to use the NO pin to drive a 5V OMRON Relay (with a led and a diode on the coil terminals) to drive a ...
I have a question about connecting of the SMPS V15SMPS pins. From the datasheet we see, that the V15SMPS_1 and V15SMPS_2 pins are connected internaly. But, on the "Figure 6. SMPS step down converter power supply scheme" they are alco connected extern...
Last week I bought a few STM32F469I-DISCO boards from DigiKey. Today I wanted to look at the schematic and found that there are two revisions available, B07 from 2015 and C01 from 2020. But I have B03! I'm wondering how old my board actually is, an...
It complains about not finding mfc140.dll.I do have mfc140.dll in C:\Windows\System32.What next?JW[EDIT] The CLI does not run either, throws the same error: After copying mfc140.dll into the directory where the stlink-utility executable is located (...
Hi,I wanted to generate interrupt on pins PC14 and PC15 on NUCLEO-F722ZE board but it doesn't work. In the board documentation I found that jumpers configuration should be as per screenshot. Since elements there are pretty small and I don't want to d...
What are the design criteria by which the oscillator for the Nucleo dev kits has been selected?
I'm trying to find a schematic diagram for the Nucleo board with the L412 processor, but can't track it down. I've looked in the User Manual for this product (UM2206 rev 5) where I would expect it to find it but it isn't in there. I'm not sure if thi...
So I bought STM32F769I Discovery Kit but only to find there is no USB connector provided to access the MCU USB FS peripheral. It only provide for USB HS, why so?How can then I do verification on the USB FS peripheral of the MCU?
