Hello everyone,I have a project in mind where I want to create a business card with an NFC tag that redirects to my portfolio page. My main concern is ensuring that the NFC tag URL redirect works on as many phones as possible. I've heard that Type 5 ...

Hello everyone, The last few days I have been trying to get Zigbee working on my STM32WB55CGU6 and I can now switch on and off a light! But the more difficult thing to get working is the WindowCover. Below you will find the image where my STM32 has c...

Hello, I'm trying to get Zigbee working on my STM32WB55CG6 custom board. I've verified that the RF section works since BLE works perfect but now I'm trying to get Zigbee working. Since there aren't alot of examples I've tried the Zigbee_OnOff_Server_...

Hello,I'm trying to use the ADC to measure the Vbat voltage on my STM32F401RCT6 but i get some strange values. Here is my setup in the device configuration tool: And here is the code with the returned values: Vref_Val = 303Vbat_Val = 932 I have conne...

I'm using an STM32F401RCT6 to create a very accurate millisecond timer for a school project. When the second interrupt of the alarm triggers i set a new CCR1 value and reset the timer. But it seems like the timer just ignores this. Only when i set a ...

So what I got from that Application Note is that I should buy a tag with a memory less than 8 kBits. That's the only hardware requirement so that I can use it with every smartphone?Thanks in advance!

Allright I've ordered a Zigbee sniffer since it's still not working. I have figured out however how to get to the logs of homeassistant and maybe it's something similar to Wireshark. Also I never get into the callback function.The log is linked below...

It works! However I expected STM32CubeIDE to generate those interrupts for me since it didn't.And I bricked my custom boards by uploading the example to it, in which the wrong MCU was selected. Can't get it to work even when using the boot0 trick.Tha...

Also whenever I set a breakpoint in APP_Zigbee_Init, APP_ZIGBEE_StackLayersInit or APP_ZIGBEE_NwkForm it never triggers which is weird.

I just measured Vbat and its 3V hooked up to the STM32. But yeah you've explained it way better than me. I have this ferrite bead hooked up to the Vref+ pin. Might that be a problem? I dont think so since it has a resistance of 120 Ohm @ 100MHz
