I acquaintedwithSTM32CubeMX amd HAL Drivers for STM32F1, but I'm really some confused.
For example SPI
in HAL Drivers User Manual I find function HAL_SPI_Transmit()
The thirdy parameters is Timeout
Documentation say Timeout is Timeout duration , of what? Why and how
OK I loot in function definition in line 400 of the xxxxx_SPI.c
Timeout is used as parametrs in function  SPI_WaitOnFlagUntilTimeout()
Unfortunately, the documentation again say Timout duration and on line 2286 is Timout compared with HAL_MAX_DE"AY.
What is HAL_MAX_DELAY I could find so far.
Documentation is a bad joke.
Is there any better documentation and examples described above function parameters?
Rr how you can become familiar with the HAL layer Drivers?
