There are three ultimate propositions in Philosophy: Who are you? From where? Where to go? For the dapm mechanism, we can ask: What is dapm and what is its function? How is dapm created? How is dapm triggered? The following is an analysis of these three problems.
First, what is dapm? This is mentioned in the overview of dapm, that is, the dynamic management of audio power supply. I believe that power management is not unfamiliar to everyone. The purpose of the dapm design is to enable the necess
For example, when we use assembly commands such as ADC and SBB, We Have To unbind the content in the flag register (EFL) for the sake of attention. View the value of each flag in binary details. Then these commands that need to use the mark register are clear at a glance. --
I can't wait to write a test code to see the secret:
# Include
Int main (void){_ ASM{MoV Al, 0xffMoV DL, 0x01
Add Al, DLADC Al, DL}
Return 0;
}
It should be explained in the form
mode register is a read/write register. The ADC control register is a read/write register used to select the active channel and encoding input range and bipolar/single polarity operations. The I/O control register is a read/write register used to configure two I/O Ports. The filter register is a read/write register used to update the data of the encoding converter. The ADC data register is a read-only regi
the end of the conversion of the regular channel, and the transformed data is transferred from the ADC_DR register to the user-specified destination address.Note: Only ADC1 and ADC3 have DMA capabilities. The data converted by ADC2 can be transmitted using the DMA function of the ADC1 via the dual ADC mode.5. Dual ADC Mode(1) Synchronous injection mode: This mode converts an injection channel group.

better solution. Figure 6 shows an example of converting a single-ended signal to a differential signal.A major application of a fully differential amplifier is signal processing in the case of an ADC input. Low-pass filters need to be used to remove high-frequency noise to prevent their aliasing into the band of interest. Multilevel Feedback (MFB) is an excellent topology that is easily adapted to a fully differential amplifier. A MFB circuit is use

If it's black, write a purple one. Anyway, a little practice.Since 8 can say, then from red to black into 16384 part, that is , said, the line is not OK, of course.

Yesterday our group of 10bit-40m ADC measured come, oneself finally can relieved, can unencumbered graduation.In the evening boss BG Whole group of graduates, drank a lot, I said to the boss: "This 3 years in the group, I have it as a career to do!" "Yes, although in these 3 years, setbacks may be more than success, joy is always intertwined with pain, but whether it is technical or work, even in the capacity of liquor, I have been honed, up to 3 year
be used in the main ADC1. The internal reference voltage Vrefint is not the same as the reference voltage. The reference voltage of the ADC is provided by the vref+ and serves as the reference voltage for the ADC converter. When we use the vref+ directly from the VCC voltage, when the VCC voltage fluctuation is relatively large or the regulator performance is poor, the internal reference voltage of the STM
The Touch Screen driver framework is similar to the input subsystem in the previous article, but the underlying driver is changed from buttons to touch screens.
