Posted on August 02, 2016 at 14:43I use two ADCs, working together on two different signals.These two signals have the same frequency and amplitude. They are shifted, Signal 2 has a phase of 90°.The DMA put the converted values in an array. This arr...

Hi,
I have a code, kindly provided by clive1, to use two ADC in dual mode on STM32F334, and it works well. I can modify some parameters, but something (the ADC itself, the DMA to fill the memory array, or ...
Posted on July 18, 2016 at 17:50Hi,I want to read two signals (supposedly quite similar) at the same time, in order to compare them. I have one ADC working, but I'm perplex about the other.- Does it matter if I use for the second signal, say ADC1_IN...
Posted on July 12, 2016 at 16:26Hi,I have a code that generates a sinewave by reading an array and putting it in the DAC, and it works pretty well, except for one detail: the amplitude I read on the oscillo is 2.64V, but won't go any higher.The arra...
Posted on July 11, 2016 at 16:08Hi,I want to write a phase comparator on my nucleo-f334.As far as I know, it works like this: two signals are sent in the phase detector. When one of them cross the zero line, a timer/counter is started, and it stops ...
Posted on August 03, 2016 at 11:12Haha don't worry the ValFreq vs Nb Samples array doesn't make much sens to me either, it was the whole point^^So if I understand, they're not complementary, it's either one or the other: if I don't use continuous mo...

Hi Clive, sorry for the delay, I've been trying to re-state my question.
First, let's pretty much forget all of the previous things, particularly the several values of any kind that could have been invol...
Posted on July 27, 2016 at 17:12Ok, so, when we talk about rising edge for triggering, it's the rising edge of the PWM, and the TIM2 period determined when the rising edge happens, if I understand correctly.Nice.The thing is, I test values for TIM_P...

You're right, I may have been greedy. I apologize.
I'm going to stick with precise questions.
In order to verify what is in the array I use printf in debug mode.
I have a problem with the display...
