Can't get max adc speed (5.3MSPS) in STM32L432KC?
I'm developing a Firmware to get a number 'NUM_POINTS' of samples from the ADC, then send to the PC trough the USART. I already have this system working, but the problem is with the sample rate. Now a days, I'm getting a 1.8MSPS with all my effort on this. I coded the system clock with the configuration to get the maximum sample rate (like the manuals says), the same with the ADC.
I have spent a lot of days trying to get the maximum ADC speed (5.3MSPS), but I couldn't get it yet. Some days ago, I found a discussion saying that the problem is with HAL lib, is it right?
I'm using Hal library and VisualGDB to code this firmware. My analog in is the Channel 5 (fast channel according to the manual).
Could somebody help me?
