STM32L5 missing drivers

Postby Cesare » Wed Oct 04, 2023 9:03 am

Good morning to all developers,
I just started developing on STM32L5 (waiting for STM32U5 support) but while taking a look at driver support at

Code: Select all

I found out those typical drivers like ADC, DAC, timers, QSPI, I2C, SPI, DMA are missing.

Any future plan for them?

If I wanted to develop these drivers myself, is it just a matter of copying from other platforms and changing the register mapping, or is there something more complex?

Thank you.

L5 development is frozen, missing driver should require limited effort, some of them probably just testing after including them in

At some point L5 will be redone dropping support for TrustZone host mode.
