One more thing, I notice “adc_calibrate” is in adc_common_v2.c, my build of
libopencm3 is using adc_common_v1.c. Should I be using v2?

Dave, Chuck, thanks for the pointers. I am, slowly working my way through the
differences.
There are a couple of methods for the ADC I can’t find in the libopencm3
documentation so I assume they have been deprecated. For example, “adc_off,
adc_reset_calibration, and adc_calibration.” Is the same functionality
available with other methods?

That is correct Sid, the F1 and the F4 have different GPIO architectures so the
flags are incompatible.

The project I am porting to STM32F411RE makes use of an ADC, when looking at
the f4/gpio.h file I don’t see “GPIO_CNF_INPUT_ANALOG” defined, in fact the F4
file has many defines not included. It is defined in the F1/gpio.h file. Does
this mean the gpio.h header needs updating for the F4? How can I resolve this?
Also, a similar situation exists for some ADC definitions. The define
“ADC_SMPR_SMP_28DOT5CYC” is defined in f1/adc.h but not in f4/adc.h.
Is it OK to use the F1 includes?
Any input would be appreciated,
Sid
