I didn't own a V3 programming device and found the $11 device did have a USB C type connector but would not supply power to the target so I purchased the STLINK-V3PWR device. When it arrive I could not find any of the shipped cables that would connec...

In STM\STM32Cube_FW_WL_V1.2.0\Projects\NUCLEO-WL55JC\Applications\LoRaWAN\LoRaWAN_End_Node\LoRaWAN I cannot find an explanation for the NUCLEO-WL55C1 LEDS GREEN, BLUE, RED meanings. In lora_app.c I found: AppLedStateOn = appData->Buffer[0] & 0x01; th...

Why do some documents use Cube-MX instead of the MX inside of Cube-IDE? I can open an IOC with Cube-IDE and do everything Cube-MX does and more so why are so many examples using just Cube-MX? I downloaded the current version of Cube-MX but it is very...

Digital camera interface (DCMI) on STM32 MCUs AN5020 lists the parts and using STM32CubeMX you can check each 'board' that has a supported MCU to see if the DCMI pins are free. I did not find any product selector that shows DCMI, MCU or board level, ...

Agree with @Tesla - I use the STM32MP157F-DK2 for anything camera/display related where processing has to be displayed in near real time. While the STM32H7 line can work it does not bring a M4 DSP + two A7 to the table to handle the presentation and ...

I was doing a follow-along for a video on STM32WL55, simple blinky. I used the CubeMX inside of CubeIDE to add do the simple code modification BUT CubeMX inside of CubeIDE did not generate the code from the IOC that allowed me to add code to the LEDS...

"Time is your enemy" Things change, corrections, new functions, renaming, third party interfaces redefine their API (thethings.network) and three months after a video is created it no longer works. And that is not the only issues: CubeMX and CubeIDE ...

After doing a lot of reading I finally found LoRa, which defines FHSS and then I came across a ST statement that only certain STM32WLx5xx devices do LoRa, the NUCLEO-WL55JC2 does and I added a P-NUCLEO-LRWAN2 for a gateway. Should keep me busy a day ...

Where to find the meaning of status LEDS from NUCLEO-WL55C1 LoRaWAN_End_Node application

Why do some documents use Cube-MX instead of the MX inside of Cube-IDE?

Reading the Seeed Studio LoRa-E5 docs they talk about SX1262 "It is powered by ARM Cortex-M4 core and Semtech SX126X LoRa chip" yet they have a STM32WLE5JC? Isn't the STM32WLE5JC a M4+Radio? The NUCLEO-WL55JC2 doesn't have a SX1262 yet it does (G)FSK..

What display (X-NUCLEO-GFX01M1 or X-NUCLEO-GFX01M2) does the STM32G071 NUCLEO Example use? The external flash loader fails.

Re: I am looking for the suitable development kit for interfacing my 'camera sensor' through parallel interface. The board should include HDMI, USB as well to display the image through to end terminal. Which STM32 dev. board I should look into?
