STM32 MCUs Products

Now impossible to design with STM32 due to no stock and/or crazy prices - is it going to change?

I' ve just visited the JLC website and this is the current stock of STM32. My open source design for a STM32H743 based computer is now dead as there aren't any. Matek, the developer of flight controllers for drones has stopped production because of a...

How can I set the SPI pins manually (HIGH or LOW)? Do I need to use the alternate function of these pins and use pin stacking? Or can I access the SPI pins in another way?

Interesting bug in SPI. Send 14 bits instead of 8 + BSY flag. (STM32L010K8) [solved]

I used SPI. 8 bit. HCLK / PCLK1 / PCLK2 is 1 MHz from HSI. I've run the standard code many times:SPI->CR1 = 0; SPI->CR1 = (0x7 << 3) | (1u << 2); SPI->CR2 = (1 << 2); // Without OVR. SPI->CR1 |= 1 << 6; // Enable.It worked. Many launches after tha...
