Context: I'm writing my first STM32 "from the ground up" project. Notepad++ and GCC in command line (Windows 10) are my IDE. I've never done this before, so I'm learning ropes, taking first look into assembly (but keeping own assembly to a minimum, C...

STM32F746-DiscoCapacitive Touch Panel FT5336STM32CubeIDE, Windows 10CMSIS-onlyI'm developing my first I2C driver for STM32F746 using CMSIS-only, and I've decided it would be great to test my I2C skills on built-in capacitive touch panel FT5336. I use...

Playing with STM32F746 disco, CMSIS-only, directly with registers, in C. CubeIDE 1.8.0, Win10. Gives a good intuitive understanding of how things work. For now, I'm practicing cascading the Timers in various ways (successfully). The thing I failed to...

Meanwhile, I found an answer to my NVIC Active Bit question.Multiple active bits can be set at the same time. As soon as interrupt handler starts, its active bit is set to 1. Even if this interrupt is interrupted by higher priority interrupt, its act...

Right now I'm playing around with CM7 and CM4, while the intention is to write small RTOS kernel for myself. For the sake of satisfying curiosity, saying that I can, I understand stuff. For future professional prospects. I can totally imagine myself ...

Thank you for your reply! I'm already familiar with almost all of this. It's that active bit specifically that I don't know about NVIC. And I have figured out PRIMASK thing too, glad too see I was right about it (found some material online). It's onl...

I still don't know, what I did wrong, it's clearly some misconfiguration somewhere, but I managed to solve it. I took parts from this article. I skipped clock enable and GPIO configuration, I'm sure they're correct, and I only copied a pair of code i...

interestingly enough, I tried the preinitconfig example, and it didn't work. Compiled it ok, but no communication. Communication only on TouchGFX project visible. As for _discovery_qspi.c, it's a part of TouchGFX project too, I studied it from top to...
