time, and there are no noticeable changes.The result of the operation is no significant change (still 105 times/s fluctuation)3) Now only the collection thread (all other threads stop) found the acquisition speed is also not going to goNext block the sub-modules of the Business Processing module, and then compile and run separately to see the results of the operation, the sampling speed still no significant changes4) To this step only the application layer code is read through the SPI bus the

CodeInstruction ADC directivesThe ADC is a carry addition instruction that takes advantage of the values recorded on the CF bit.Format:ADC Action object 1, operand 2Functions: manipulating objects 1 = manipulating objects 1+ manipulating objects 2+cfFor example: ADC AX,BX is implemented with the following functions: (AX) = (AX) + (BX) +CFLet's take a look at two

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

inside.Give a few examples,Practice it yourself, such as writing red, green, blue, yellow, pink, gray, and then quickly writing out the color of the main hue of your mouse pad. 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

instead of calculationIn a situation where processor resources are tight and memory resources are relatively rich, it is possible to swap storage space for running speed. For example, if a sine or cosine function value is frequently calculated, the function value can be computed in advance and placed in memory for later arm lookups. (2) Make full use of the RAM in the chipSome manufacturers of ARM chips in the integration of a certain amount of RAM, such as

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 of

stored, but also the large enough SRAM needs to be integrated in the chip. This increases the cost of chips. This is not necessary because it can be solved in a better way. The startup Code cannot be too large, which means it is not complicated and has a single function. Therefore, you can only use your mind to start the code loading program. The program loaded by the boot program is called Bootstrap and not bootloader. Why is Bootstrap not called bootloader? It's not that

Most people who have studied single-chip microcomputer know the names of "Water lamp" or "horse lamp". The specific implementation effect is to display a group of changes cyclically according to a fixed rule. For example, if you use a byte length space to realize the "marquee", you can change the value of this Byte as follows: "0000 0001b"-> "0000 0010b"-> "0000 0100b"-> "0000 1000b"-> "0001 10000b"-> "0010 10000b"-> "0100 10000b" -> "1000 10000b"-> "0000 0001b" (loop) For example, to change th
