RM0316The reserved space is clearly indicated at the top, and the style changes abruptly on the next page, and the reserve is no longer specified. what is the result of missing addresses ? why can't a single style be maintained ? for clarity.

Add CubeMX support for dual buffer DMA in ADC modes.

This is a suggestion, not a question...There's no support for dual buffer DMA mode in the ADC HAL, and it would be very easily added.Already did my own copying the existing function for the multimodeDMA.The problem is that CubeMX will wipe the code a...

Is there any required external circuitry for the ADC?

I am using a current sense amplifier (INA190) to measure current. The output of the current sense amplifier will go to the input of the ADC on the STM32. The output range will (ideally) be between (0-VREF). From working with an external 16 bit ADC, I...
