Where are the HAL libraries documented?

[mleo2]

I've just spent hours trying to get a DMA to trigger and interrupt when transfer is complete. I was using HAL_DMA_Start() instead of HAL_DMA_Start_IT(). I found HAL_DMA_Start_IT() by looking through the source code.

Where are the HAL libraries documented?

There should be an User Manual for each family; eg,

https://www.st.com/resource/en/user_manual/um1785-description-of-stm32f0-hal-and-lowlayer-drivers-stmicroelectronics.pdf

See the Product Page for the appropriate Cube package; eg,

https://www.st.com/en/embedded-software/stm32cubef0.html#documentation

Right, Andrew, and just what i do:

most times you know, what you want : maybe you have set an UART in Cube, to receive something with INT mode,

then (after : generate code ! ) just open the (your project name): drivers->xxHAL..->Src-> xxhal_uart.c

and look at the possible functions :

So if you want receive with INT, see there short description:

So you see: how to write, parameters , etc.
