When uploading a blink program to an STM32 MCU installed in a custom PCB, the LED turns on but it does not turn off.
I have a board with a STM32F103RET6 with many things, and a blue and green LED's connected to GPIO pins. To test if it works correctly I'm using STM32 cube IDE to upload a program that blinks the LED's, and the LED turns on but it does not turn off a...
What is pros/cons of using I-cache and D-cache in SPI communication ?
I am currently trying to implement Interrupt-based SPI communication. I was looking through the examples given by STM and came across a line that enables the above-said cache. I was wondering what advantages it confers?

Have you ever seen this marking scheme without "ST" in the first row? CAN it even be legitimate?
In normal times I would never thinking about buying from a no-name small Chinese seller, but I'm very desperate ATM
How to set my timers to 0V when off?
I am having this problem with a variety of signals but let's take for example a 10 kHz signal. I am using the repetition counter to count 9500 times (950 ms) and then be off for 50 ms before turning back on. During the repetition counter part my sign...
