The 7219 uses a three-pin interface that is SPIcompatible A 16-bit data word (more on that shortly) must be serially shifted into the chip via the DIN (data in) pin, under the control of the CLK (clock) pin Each data bit that is placed on the DIN line is shifted into the 7219 on the rising edge of the CLK line The most significant bit (MSB) of the data word should be sent first; the high byte of the word should contain the address of the 7219 internal register into which we want to place the data, and the low byte should contain the value of the data The 7219 has a total of 14 internal digit and control registers We will primarily be concerned with the four that are listed in Table 12-1 and the address registers for the LED digits themselves, which we ll soon discuss When both bytes have been serially shifted into the 7219, its LOAD pin must be briefly pulsed in order for the data to be actually displayed on the LEDs Table 12-2 lists the 16 BCD characters that the 7219 can automatically decode Conveniently, the BCD value for each of the ten digits is the same as the digit itself If you want to light the decimal point to the right of any character, just add 128 to the corresponding BCD value (ie, set bit7 to 1 ) For example, to display a value of 52, you would send the following two values to the LED display: 133 (5 128) and 2 The programming requirements for a sevensegment LED display usually include what s referred to as a lookup table, which serves to convert the value of a specific character to the corresponding pattern of segments that need to be lit to display the character Since we re going to use BCD decoding in our project, we ll be able to avoid this programming chore However, in case you re interested in being able to display characters other than those listed in Table 12-2, Figure 12-2 (Table 6 in the 7219 datasheet) presents the standard segment-labeling convention for a seven-segment LED, along with the 7219 s.

Android that this application requires certain security privileges. For example, if an application requires access to the contacts on a device, it requires the following tag in its AndroidManifest.xml file:

.

We ll revisit the AndroidManifest.xml file a number of times throughout the book because we need to add more details about certain elements and specific coding scenarios. Now that you have a basic understanding of the Android application and the AndroidManifest.xml file, which describes its components, it s time to discuss how and where an Android application executes. To do that, we need to talk about the relationship between an Android application and its Linux and Dalvik VM runtime.
