create android app to control raspberry pi

40 Gpio on a Raspberry Pi is the best thing to play.They can be directly controlled by c,/c++, Python, Java and other languages.Now, let's see how to do the same thing with node. js.Before you try, install node. js, and move to: 1. Prepare the Test foldermkdir/home/pi/documents/test-gpio-demo/2. Create a file Package.j

(decorated with @ post) The first route is very simple, that is, reading the index template (the template is html) and sending it to the client (browser), because the path is "/", that is, for example, the IP address of Raspberry Pi is 192.168.0.10. Use http: // 192.168.0.10: 8080 to access our "/" route (the default port of the bottle is 8080) Similarly, the second route path is "/cmd", that is, access ht

) {});}); Yes, just the three lines of code ... 1th, 2 line to all the buttons (button) bound a click of the event, the third line calls the jquery post method to send This.id (the ID of the clicked button), sent to "/cmd" This path, at this time, our Python code of the second route to work, Received the ID of the clicked button on the webpage, and printed out the "pressed button: XXX" Of course, here are a few if statements to judge, you can follow the actual needs to do some real

tube. The pin is also attached to any of the Raspberry Pi's gpio ports. OE is the output enable PIN, which is also common in other chips. The function is to control whether the data in the latch is ultimately output to the Q0-Q7 output pin. Low-power output, high-power normally not output (neither high-level, nor low-level but high-impedance state, no power). In order to facilitate direct connection to

Raspberry Pi II has come! This is a boon for those who want to study Android. The official configuration is as follows: 900MHz Quad Core ARM Cortex-a7 processor (Broadcom BCM2836) 1G LPDDR2 SDRAM (Micron) Two full-size USB ports (available for power supply) One MicroUSB interface A full-size HDMI interface 3.5 mm Audio Interface RJ45 Ethernet Cabl

1. Effect display2. Hardware devicesIn a treasure bought a 4-bit common yin digital tube. 4 Number of common one cathode, altogether 12 pins. One of the 6,8,9,12 is a common-yin pin.　　Each number consists of A-g 7 diodes and a point DP. Because it is bought online without detailed device manuals, you can only test the pin and the digital diode on the corresponding relationship.　　You can see that the number 12th pin corresponds to the first digit of the common yin pin, the number 1th pin correspo
