MSP430 microcontroller adconverter 20:14:05 | classification: MSP430 microcontroller | report | font size subscription I. Brief Introduction: The adc12 module consists of the following parts: the input 16 analog switches (eight external channels, four internal channels), the ADC internal voltage reference source, the adc12 kernel, and the ADC clock source, collection and holding/trigger source,

single-chip microcomputer is 1.8v ~ 3.6v low voltage. The power consumption of Ram data is only 0.1 μA, and the maximum leakage rate of I/O input ports is 50na. MSP430 has normal working mode (AM) and 5 low-power working modes (lpm0 ~ Lpm4 ). When the power supply voltage is 3 V, the current in various modes is AM: 340 μA, lpm0: 70 μA, lpm2: 17 μA, lpm3: 2 μA, lpm4: 0.1 μA, single-chip microcomputer can easily switch between various working modes. The ultra-low power consumption of MSP430 makes

, and 16 for the apb1 divider. The output path is used by apb1 peripherals (pclk1, with a maximum frequency of 36 MHz), and the output path is sent to the timer (timer) 2, 3, and 4 frequency divider. The frequency multiplier can be set to 1 or 2. The clock output is used by the Timer 2, 3, and 4. ⑤ Send it to the apb2 divider. Apb2 divider can be divided into 1, 2, 4, 8, and 16. The output channel is used by apb2 peripherals (pclk2, maximum frequency 72 MHz), and the other channel is sent to the

sprinkler and an electric rice cooker. Therefore, the Raspberry Pi Plus relay can fully extend its control over external devices. Dry-reed Relay refers to the reed relays, which are compared with the general relays, and their switching speed and life are greatly improved. The use of the relay is very simple, only the level control of its pin to complete the control of the relay. After entering the source directory, enter in the terminal:CD "Grove-relay"sudo python relay.pyThe Rasbperry Pi wil

Ad/da input and output, PWM and other underlying hardware control, the. Net Micro Framework official low-level driver code and the upper C # library do not encapsulate these functions, so to add the control interface of such hardware, it is necessary to design from the bottom to the full. The collection of ad analog quantities is not as simple as it might be. From the conversion mode, there is a single conversion, continuous conversion points, from the model, there are scanning mode and discont

For example, there is a dictionary as follows:>>> dic = {"Name": "Botoo","url": "Http://www.123.com","Page": "88","Isnonprofit": "true","Address": "China",}The desired output would be as follows:First gets the maximum value of the Dictionary max (map (len, Dic.keys ()))Then useStr.rjust () Align RightOrStr.ljust () Align LeftOrThe Str.center () center method has a sequence of outputs.>>> dic = { "name":"Botoo", "URL":"http://www.123.com", "page":" the", "Isnonprofit":"true", "Addr

will save I/O Ports, for example, the above 4x4 = 16, 8 Io can be made with 16 buttons, 8x8 = 64, 16 Io can be made with 64 buttons. Advantages: Multiple buttons can be used with less I/O to make sure the buttons are accurate; Disadvantages:The program is one step more than the I/O buttons. (2) I/O buttons This is relatively simple. It uses the high and low levels of an IO port to determine whether the key is pressed. Advantages:The procedures and hardware circuits are relatively simple, and th

A 10-bit cmos adc (analog/digital converter) is an 8-channel retained input device. The analog input signal is a 10-bit binary digital encoding, A/D conversion, also known as analog-to-digital conversion, which converts analog signals The digital signal that the computer can process. For S3C2440, the implementation of A/D conversion is relatively simple. The main thing to do is the ADC control register ad
