I need to send 2 bytes over the I²c bus with a STM32L432 as slave and a Raspberry Pi as master. But the clockpulse of the SCL is to wide.

In the code below I send 2 bytes with my STM32 (I've chosen a number higher then 255 (340) so it needs to send the data in 2 bytes) but on the scope I cant find this data. I guess it's because of the wide clockpulse and the Rpi expect an ACK. Instead...

Using flash algorithm from F103 for F405

Hi,I am trying to use a flash write and read module written for the STM32F103 on an STM32F405.However the F103 deals with pages and subpages. Some algorithms depend on subpage size. The F405 has sectors, which I guess are the equivalent to pages, but...
