It's no secret that there is a worldwide shortage of STM32 MCUs and distributors are not even trying to estimate availability.How is STmicro addressing this?

I'm considering STM32G431 for a motor control project with 4 stepper motors driven by step and direction.Can all 4 steppers be controlled by using TIM1's four PWM Generation channels 1 thru 4 and be made to move by different amounts of pulses simulta...

Trying to decide if TouchGFX with some variant of STM32H7 is the right solution for us and the Boss wants to know how big of a screen we can expect to drive and still get quality resolution and snappy feel. How do I determine memory requirements and ...

STM32G474CE: Is it possible to use I2C2 in SMBus 2-wire mode with DMA? Asking because CubeMX (with STM32CubeFW_G4 1.4.0) does not show the "DMA Settings" tab if I2C2 is set to "SMBus-two-wire-interface." Bug in CubeG4 or hardware limitation?

I can't seem to find it in the datasheet: what is the max allowed kernel clock frequency for SPI123 and SPI45?

@TDK thank you!

@Community member are you talking about a QSPI flash memory for things like bitmaps? Which STM family have you used for graphics? I was looking at the H7 but it seems the L4 might actually be more capable (supporting touch sensing within the SoC fo...

@ktrofimo thanks very much for your answer. Are you using the TouchGFX software to manage what's displayed on the screen? Regarding the visible glitches you mentioned, was that due to hardware limitations or software issues?

@Community member thanks for your reply. A few months ago I looked into TouchGFX a little and seem to recall that some formulas were shown to calculate the memory requirements etc., but I can't seem to find that information now.1024x768, supposing e...

Hello @Singh.Harjit , thanks for your reply.I saw that exact same section of the Reference Manual, but I think it is written in a confusing way. From my interpretation, it is not saying that these I2C support DMA in SMBus mode; rather it is only say...
