Should pin PA9 needs to be connected to something on the board and is there any way to call the eventcallback function.My main issue is that the wired mouse is not asensed by Vbus.Its voltage is 0V. Could you please help me on this.Any help would be ...
I have just moved from ST-LINK/V2 ISOL to STLINK-V3SET. Win7-64. 24GB RAM. A very stable machine and I have two identical ones.The reason for V3 was to see if the SWV ITM debug mode was more reliable (or occassionally loses a byte or so), and I read ...
Hi, I'm trying to design the STM32L4R5 IC on my PCB board and use the STLink V2 as the debugger. Should I use the SWJ or SWD debug port options? What are the pros and cons for both?Since the STLink V2 is a 20 pin JTAG connector, how do I connect the ...
Hello everyone, Are there any boards that will allow me to run the MCU at 180MHz or more , while still supporting the use of the FullSpeed USB at 48MHz? The board should have at least 2 ADC's & 1 DAC.Please suggest how may I achieve this !Thank you.
Hello Community!I have a project where I was using a STM32F407 MCU from a minimal ready-to-run system with USB, programming connection and pin headers to access every MCU pin. While using this hardware, the project can be loaded and executed on the M...
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...
