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...

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...

Hi @IssamosThanks a lot for helping.It looks like a good simple example (with all relevant code in main.c, compared to 50+ files in the Discovery board example previously mentioned). Also like it uses LL library, which can easily be converted to dire...
