SIM900 GPRS data transparent transmission module b
no vote
Application background To achieve the most basic GPRS communication function, and provides the lowest energy consumption demand.On this basis, the software function for the development of ucosII - based on the 2.92 version, demo software provides open source hardware, originalSchematic of the open source software, not part of the open source lib library, lib library, open source is not part of AT instructionThe current operation. Key Technology Due to the application of the Internet of things and the advancement of GPRS data services in various industries, the similar design products in the marketThe field will still occupy a large area. At the same time, the existing product development will be customer oriented and modular design, a separate designThis module, users only need to use a few parameters can be set up immediately, at the same time, the module will realize the normal work and low powerJob two modes.

Application of embedded TFTP server based on W5500
4.0
Application background The following W5500 for the TFTP client, to achieve TFTP communication process about how to test Key Technology To observe whether the APP application download and start successfully, the operation is LED water lamp as an example. Serial information TFTP  SUCCEED, illustrate the file downloaded successfully, and then print the serial port of APP message. APP updateTo observe whether the APP application download and start successfully, the operation is LED water lamp as an example. Serial information TFTP  SUCCEED, illustrate the file downloaded successfully, and then print the serial port of APP message. APP was successfully updated, observe the development board also found that LED in accordance with the requirements set lights flicker.Power, observe the development board also found that LED in accordance with the requirements set lights flicker.

EMWIN experiment soft keyboard test
4.0
Application background This experiment will achieve the following functions: this experiment mainly explain how to make and use the font in the EMWIN on the external SPI FLASHNote: this experiment uses the UCOSIII operating system, the experimental use of the touch screen, this experiment based on 4.3 inch 800*480 resolution of the screen, if you use 2.8 or 3.5 inch screen display is not complete. Key Technology Platform: ALIENTEK STM32F4 Explorer +4.3 development board inch screen (or a new 7 inch screen)Environment: EMWIN+UCOSIII+FATFSNote: currently only F4 version, and is for the 800*480 resolution of the screen, so only 4.3 inches and the new version of the 7 inch screen can be perfect operation, if it is 2.8 or 3.5 inch screen display is not complete.

Dissolved oxygen measurement
no vote
Application background The content of dissolved oxygen is related to water temperature, oxygen partial pressure, salinity, water depth, water depth, and organic concentration of oxygen consumption.      dissolved oxygen content in water is affected by two kinds of effects: one is the oxygen consumption of DO, which includes aerobic degradation of organic substances, biological oxygen consumption; the other is to increase the effect of DO, the main air dissolved oxygen, water plants, etc.. The interaction of these two kinds of interactions, so that the dissolved oxygen content in water presents a temporal and spatial change.      in natural condition, water in the flow, the complex oxygen process is more rapid, more easy to add water oxygen consumption, so that the water dissolved oxygen to maintain a certain level, and vice versa, in still water conditions, the complex oxygen process is slow, the oxygen in the water can not be added, in
