HiI’m using CubeMX 6.12.0 with a STM32U5G7VJT6Q project.When using a fractional divider setting for PLL3 (in the RCC System Clock configuration), CubeMX generates the below LL library code.The LL_RCC_PLL3FRACN_Enable() is correctly included, but it s...

Anyone have some insider knowledge or just plain rumours of what chances are for ST considering releasing a STM32H7 with larger RAM in the near future?Like 3MB or larger, as some STM32U5’s have (I also just noticed some competitors having large RAM d...

HiI’m looking to use LVGL on a STM32H7 with LTDC for driving a 4.3”, 800x480, no-touch display with 16bit (RGB565) parallel interface.The ST document titled ’Out-of-the-box GUI Software (BSPs) available for STM32 display kits’ (link below) indicates ...

In CubeMX when configuring a SPI peripheral I can only choose either 8 or 16 bit, but the STM32G491 reference manual says data size can be from 4 to 16 bit. Is this a bug in CubeMX?(using the newest CubeMX version)

HiI am trying to make an analog synthesizer, and for this is using a STM32G431 with some 8-channel DAC’s (connected via SPI) for generating control-voltages for the VCA’s and other circuits.I would like to use the SPI with DMA, and have looked at the...

Hello TDKThanks for the PSRAM suggestion, I will look into this.Best regards,Pete

Hi GhofraneThanks for helping.Did you acknowledge it as a ‘bug’ in CubeMX? (I’m a bit unsure since you replied “and that's why CubeMX offer those two options”)Also, the datasheet mentions the range is from 4 to 16 bits (4,5,6…16), not only 4, 8 or 1...

Thanks for the suggestions. Will have to look for something more powerful than STM32Although I don’t need 48kHz sample rate, like in a music player application. Something between 10 – 20kHz will probably be fine, but needs listening to the analog cir...

Hi @AScha.3No misunderstanding at all, I think:)I’m in the process of building it, but far from finished. Analog circuitry is done, but have only recently begun the digital part.It’s only analog. The DAC channels are connected to voltage-controlled a...
