Description
The ADS1232 and ADS1234 are precision 24-bit analog-to-digital converters (ADCs). With an onboard, low-noise programmable gain amplifier (PGA), precision delta-sigma ADC and internal oscillator, the ADS1232/4 provide a complete front-end solution for bridge sensor applications including weigh scales, strain gauges and pressure sensors.
The input multiplexer accepts either two (ADS1232) or four (ADS1234) differential inputs. The ADS1232 also includes an onboard temperature sensor to monitor ambient temperature. The onboard, low-noise PGA has a selectable gain of 1, 2, 64, or 128 supporting a full-scale differential input of ±2.5V, ±1.25V, ±39mV, or ±19.5mV. The delta-sigma ADC has 23.5-bit effective resolution and is comprised of a 3rd-order modulator and 4th-order digital filter. Two data rates are supported: 10SPS (with both 50Hz and 60Hz rejection) and 80SPS. The ADS1232/4 can be clocked externally using an oscillator or a crystal. There is also an internal oscillator available that requires no external components. Offset calibration is performed on-demand and the ADS1232/4 can be put in a low-power standby mode or shut off completely in power-down mode. All of the features of the ADS1232/4 are operated through simple pin-driven control. There are no digital registers to program in order to simplify software development. Data are output over an easily-isolated serial interface that connects directly to the MSP430 and other microcontrollers.
The ADS1232 is available in a TSSOP-24 package and the ADS1234 is in a TSSOP-28. Both are fully specified from -40°C to 105°C.

FAQ
1. What cards can the machine copy?
The machine can copy the elevator cards of the entrance guard of the residential area. It can not be used for illegal purposes except this. It does not support the replication of water.
Food Card, Bank Card, Credit Card, Campus Card, etc.
2. Can you change the date, floor and amount data?
The equipment only has the function of cloning and duplicating, and has no function of postponing and changing the amount of money. We can not provide such teaching.
3. Can you copy the parking card of the underground garage in the residential area?
Parking cards can be duplicated. It is necessary to confirm the type of cards and whether to swipe them in or out. If you bring in and out restrictions, the duplicate cards will not be able to enter after the main card is admitted.
4. What is C card and ID card? How to distinguish them?
IC card and D card are two different types of chip cards. Different cards need different machines and replication cards to copy clones. See the details below for the resolution method.
5. Why can't my old card write data?
Common card and replication card are two different kinds of cards. Because the common card chip has been solidified and written to death, it can not write information, so it can not be used as replication card. Replication needs to buy special replication card.
6. Can multiple cards be combined?
There is no way to combine multiple cards. A duplicate empty card can only write the information of one card!
7. The decryption is successful. What's wrong with duplicating and writing cards?
Entrance guard elevator system with firewall identifies and detects replica cards so as to shield them. At this time, special replica cards of firewall type need to be used and locked after writing cards in order to achieve replication effect.
8. Is decryption replication 100% successful?
Because the use of machine replication cards belongs to the technical category, different access elevators in the market use different technologies, most of them can be replicated! But there is no guarantee of 100% success!

5. Support ESP32
ESP-WRoom--32 is a general-purpose Wi-Fi T BLE single-chip microcomputer module with powerful functions and a wide range of uses. It can be used for low-power sensor networks and demanding tasks, such as voice encoding, audio streaming, and MP3 decoding Wait.
The core of this module is the ESP32-D0WDQ6 chip, which is scalable and adaptive. The two cpu cores can be independently controlled or powered on. The adjustment range of the clock frequency is from 80MHz to 240MHz. The user can cut off the power of the cpu and use the low-power coprocessor to continuously monitor the status change of the peripherals or whether certain analog quantities exceed the threshold. ESP32 also integrates a wealth of peripherals, including capacitive touch sensors, Hall sensors, low-noise sensor amplifiers, SD card interface, Ethernet interface, high-speed SD10SPI, UART, 12S and 12C, etc.
Cpu and memory
ESP32-D0WDQ6 has built-in two low-power XtensaB332-bitLX66MCUs.
On-chip storage includes: 448KB of ROM, used for program startup and kernel function calls. 520KB on-chip SRAM for data and instruction storage. 8KB of SRAM in RTC, that is, RTC slow memory, can be accessed by the coprocessor in Deep-sleept mode to 8KB of SRAM in RTC,
That is, the RTC fast memory, which can be used for data storage and accessed by the main CPU when the deep sleep mode rtc is started. 1kbit eFuse, of which 256bit is dedicated to the system (MAC address and chip setting); the remaining 768bit is reserved for user applications, which include flash memory encryption and chip ID.
