They are used in embedded applications such as those found in robotics, video games, power tools, remote controls, and toys. DB Connector 18 1 36 19 Figure He has authored numerous books on the subject of microcontrollers.
Also, as you place a byte in upper RAM, give a copy to P0. Place the sum in R7 and R6; R6 should have the lower byte. To correct this problem, the programmer must add 6 to the low digit: In other word, while the source but not after INC can be an operand of any addressing mode, the destination must be in register A in order for DA to work. The final result is in BCD format.
The result must be in BCD. Add it to the minuend A Subtraction of 3. A MOV B, 10 ;load 10 to reg. Save it in R7, R6 and R5.
After each division the remainder is saves. Write the magnitude of the number in 8-bit binary no sign 2. Invert each bit 3. If it does, send 99H to P2; otherwise, it stays cleared. XRL can be used to Solution: If both registers have the same value, 00 is placed in A.
Instruction According to the test results, place the temperature value into the registers indicated by the following.
Put two highs at the start and end of the data. Send the byte LSB first. Serializing Data Solution: MOV C,P2. D7-D4 D3-D0 after: Single Bit Solution: Ports P0 — P3 are bit- Solution: This is widely used for the new generation of microcontrollers. Using the inverting and Ex-OR operators, respectively. Bit-wise Solution: Checksum Byte Solution: RAM Data Solution: Examine the contents of the code space to locate the values.
The LSB should go out first. The MSB should go out first. The LSB should come in first. The MSB should come in first. Verify also that the information is not corrupted. FILE Solution: We convert the value from hex to binary. From Figure we have: Start the timer Program 4. Stop the timer 6. Clear the TF flag for the next round 7. TMOD is loaded. Steps to Mode 1 6. Timer 0 counts up with the passing of each clock, which is provided by the crystal oscillator.
At that point, the JNB instruction falls through. In other words, Timer 0 counts up each 1. In the timer delay calculation of Example , we did not include the overhead due to instruction in the loop. To get a more accurate timing, Mode 1 we need to add clock cycles due to this instructions in the loop.
CLR P2. This plus Rolling over to 0 goes through a total of clock cycles, where each clock is 1. Find the delay in ms. To get the largest delay we make TL and TH both 0. Programming CLR P2. As a result, it goes through a total Of states. In your calculation do not include the overhead due to Instructions in the loop. Also notice that the high portion and low portion of the square wave pulse are equal. In the above calculation, the overhead due to all the instruction in the loop is not included.
Divide the desired time delay by 1. Perform — n, where n is the decimal Values value we got in Step1 3. Show the program for timer 0 to create a pulse width of 5 ms on P2. Mode 1 Solution: Programming This means that out of many 1.
To get that, we divide one by the other. Mode 1 This is similar to Example , except that we must toggle the bit to generate the square wave. Look at the following steps. The program is as follow.
Start timer 4. Clear the TF flag 6. First notice the target address of SJMP. In mode 2 we do not need to reload TH since it is auto-reload. Steps to Mode 2 You can use the Windows scientific calculator to verify the result Program provided by the assembler. Remember that we only use the right two digits and ignore the rest since our data is an 8-bit data. Since ports are set up for output when the is powered up, we make P3. In other words, we must configure set high the T1 pin pin P3.
Use Timer 0, mode 1 bit to create the delay. Use Timer 1, mode 1 to create the delay. Use Timer 0, mode 2 8-bit auto-reload to create the delay. Use Timer 1, mode 2 to create delay. Start the count at 0H. C Programming Solution: Set by HW at the begin of the stop bit mode 1. And cleared by SW Note: The TH1 is loaded with one of the values to set baud rate for serial data transfer Programming 3. The SCON register is loaded with the value Serial Data 50H, indicating serial mode 1, where an 8- bit data is framed with start and stop bits Transmitting 4.
TR1 is set to 1 to start timer 1 5. The character byte to be transferred serially is written into SBUF register 7. The start bit is transferred 3. The 8-bit character is transferred on bit at a time Importance of 4. TH1 is loaded to set baud rate Programming 3. The SCON register is loaded with the value 50H, indicating serial mode 1, where an 8- Serial Data bit data is framed with start and stop bits Receiving 4.
P1 and P2 of the are connected to LEDs and switches, respectively. The program should perform part a once, but parts b and c continuously, use Programming baud rate. Serial Data Receiving Solution: The 8-bit character is received one bit at Importance of time RI Flag 3.
Doubling Baud Assume that XTAL TION Solution: Also, Rate HyperTerminal in Windows supports this and other baud rates. Assume a SW is connected to pin P1. Use Timer 1.
Use 8-bit data and 1 stop bit. IN C Solution: Do this continuously. Set the baud rate at , 8-bit data, and 1 stop bit. Assuming that SW is connected to pin P2. Transmitting and Receiving Solution: Use the second serial port with 8-bit data and 1 stop bit.
We can only use Timer 1 to set the baud rate. Set the baud rate at , 8-bit data and 1 stop bit. Use Timer 1 for baud rate generation. McKinlay — This textbook covers the hardware and software features of the in a systematic manner. Using Assembly language programming in the first six chapters, in Provides readers with an in-depth understanding of the architecture. From Chapter 7, this book uses both Assembly and C to Show the interfacing with real-world devices such as LCDs, keyboards, ADCs, sensors, real-time-clocks and the DC and Stepper motors, The use of a large number of examples helps the reader to gain mastery of the topic rapidly and move on to the topic of embedded systems project design.
Microcomputers are small computers that are located on single integrated circuits. They are used in embedded applications such as those found in robotics, video games, power tools, remote controls, and toys. Microcomputers are frequently used in devices and products that operate automatically. The book provides a systematic coverage of the software and hardware features of the microcontroller. The is the most widely produced and frequently used microcontroller in the world.
Its popularity has led to the creation of over fifty companies. The text is organized into 17 chapters and 8 appendices.
The first six chapters provide a coverage on the basic architecture of the microcontroller, using Assembly language. From the 7th chapter onwards, both C and Assembly languages are used to show how the interfaces with devices such as keyboards, LCDs, stepper motors, and sensors. Numerous examples are provided to help students grasp the material. This New edition has several salient features. New chapter topics such as C Programming, DS real-time clock chip, and optoisolators, have been included.
Many chapters feature newly added sections, in keeping abreast with technological advancements. Introduction to Computing? The Microcontrollers? Branch Instructions? Interrupts Programming in Assembly and C?
