Lecture

edsim51 - hardware - component and connection

8051 - Conditional Jumps and Time Delays

8051 - Subroutines and the Stack ( example program - stack role in subroutine call.asm )

8051 Address modes : indirect address mode

Learning of instructions： CPL, NOP, DJNZ, CJNE, PUSH/POP, CALL(ACALL, LCALL), JMP(SJMP, AJMP, LJMP), etc.

Learning of programming with edsim51： Rn or ARn? A or Acc? using 0

Program examples

Learning of instructions and programming: ANL, ORL, “MOV @Ri,A”, 2FH.0, etc.

Program examples

EdSim51 Example 7: Scanning the Keypad

(Note: 1. Observe the change in R0. 2. What update frequency is better? 3. Observe the content of the stack during scanning.)

ICP-A05-prep - keyPadScan as a subroutine (key numbers 3 ~ 8 go wrong).asm

ICP-A05-prep - keyPadScan as a subroutine.asm

In-class Practice

ICP-A05-01 : Scanning the keypad continuously and storing the key number (without using interrupt) [Solution]

(Note: This program tends to have a problem of repeatedly storing key numbers.)

ICP-A05-02 : Scanning the keypad continuously and storing the key number (without using interrupt) (preventing repeated storing)

ICP-A05-03 : keyPadScan driven by a timer interrupt [ solution ]

Learning of instructions and programming:

Old exams

Please finish this：非實名登錄

Program examples

1. parity bit test.asm

2. EdSim51 Example 8: Transmitting Data on the 8051 Serial Port

Note: Select “4800 Baud Rate” in the UART device.

Question: In this program, what binary code is moved to SBUF when 'a', 'b', and 'c', respectively, are to be transmitted to the UART device?

Answer:

Symbol to be transmitted to the UART device:

'a' (= 01100001Y)

'b' (= 01100010Y)

'c' (= 01100011Y)

Binary code transmitted from the processor

(Binary code moved to SBUF):

Question: When you select "Even parity", "No parity", or "Odd parity" in the UART device, what symbols appear on the display of the UART device.?

Answer:

Parity selected in the UART device:	Even parity	No parity	Odd parity
Symbols shown on the UART device:

Summary: Parity issue of a, b, c

Before running the program, set some breakpoints. Run the program and observe the TI flag when it changes to 1.

In-class Practice

Learning of instructions and programming:

Program examples

EdSim51 Example 9: Receiving Data on the Serial Port， Example 9 with clearer comment

Answer the following questions with "Even parity", "No parity", or "Odd parity", respectively, in the UART device.

Question (A): Enter "012345" in the Tx window and press "Tx Send". What data are stored in the RAM?

Question (B): After the processor receives and stores the data, what is the value of PC?

Question (C): Press "Tx Reset", enter additional symbols "6789" in the Tx window, and press "Tx Send". What are the additional data stored in the RAM?
