Internal ADC

[harry123]

hello everyone

Using the internal ADC(polling method) of the stm32f429 board the samples that im getting are too many for one cycle of analog input

how to reduce the samples without giving a delay, like if I want 128 samples for one cycle.

Vin is 300mV

APB2 is 90MHz

Clock Prescaler is PCLK divided by 4

Resolution 12 bit

Sampling time 3 cycle

Convert using DMA and trigger the ADC with a timer. You can get exactly how many samples you want.
