i have to make a project with 8051 (frec 21Mhz) microcontroller with external memory RAM(6264 8kx8) and ROM(2764 8kx8).external timer 8253,external Pio 8255 with 4 cells common annode.the project reprezent a washing machine.i need help to make the machine code(assembler) for cells -multiplex display and i need help to know how connect the keyboard with 3 functions (f,t,s) an 5 taste.i need help four interrupts,keyboard,display,code machine
Sounds like a fun project! If you choose a 22.1184Mhz crystal, you'll also be able to generate serial data and interface your target to a PC serial port. This is fantastic for troubleshooting, and controlling your system from the PC during development. (Just a suggestion).
Pick one thing to start with, and let's get started. Start with a schematic. Get your processor drawn, your crystal, your power supply, and your reset circuit. These are the fundamentals. When you have this drawn, post it here and we'll help you move to the next step.
Good luck!

this is the schematic...but i don't know if they are in a corect order..i ca't make to work the display maybe if i don't make a good program.i need a opionion urgent.must to finish the project in maximum 2 weeks:(( please help.i need a oven in proteus and i don't know how to connect. t
Well, first question is, "did you design this?"...
I notice you're using external code memory (2764 EPROM). Your processor won't be able to fetch from this unless you connect the PSEN line to it...
I suggest you read about the PSEN line in the datasheet to fully understand what I'm talking about here...
Also, on your external RAM chip (6264), you don't have the CE line enabled. This is a must. Make sure to tie all unused inputs either high or low, depending on what they're suppose to do...
Next question, can you explain how you are proposing to control the 7-SEG displays to me? I'd like to understand what you think you are doing...
Keep up the good work!

this is a homework for a project at university and the component can't be the same.they differ by person to person.i need some materials with 8051 microcontroller if you can to help me.the 7 segment display must start when the relaxing of taste made.i need book wrote by mazidi. 8051
I'm sorry, but I am getting confused. You mention "taste" in your last message, but you mention a "washing machine" in your first message.
What exactly are you trying to build here? A washing machine is a machine that can be used to wash clothing. It has several "cycles" that can be chosen for delicate, sturdy, or normal clothing. It also can have features like how many times to rinse the clothing.
Taste is something your mouth does when you eat food...
sorry for any confusion, but let's start again, and help me to understand exactly what you want to accomplish. Once I understand this, I will be able to point you in the right direction...

sorry my mistake.must to make a washing machine with the 8051 controller withe external ram an external rom,external timer,external pio with 4 7 segment display and a keyboard with 3 function F T S and 5 operation.
1.CPU Type: 8051; 2. Frequency of the CPU: 21Mhz; 3. Type and the memory ROM: 2764 8kx8 externa; 4. Type of organization RAM: 6264 8kx8 externa; 5. Timer circuit type: external 8253; 6. Type circuit parallel port: external 8255; 7. soaking1 Ti1 time: 25min; 8. soaking2 Ti2 time: 32min; 9. soaking3 Ti3 time: 43min; 10. wash1 Ts1 time: 19min; 11. wash2 Ts2 time: 31min; 12. rinsing1 TC1 Time: 25min; 13. rinsing2 TC2 time: 36min; 14. drying1 Tu1 time: 23min; 15. drying2 Tu2 time: 32min; 16. Number of cells display led 4 cell displays 8051
if you can help me i need to make the machine code.this with MOV,MOVX,DPTR....for display 7 segment to work in scheme.i'm a beginner programmer and i can't make this.i'm finish de scheme but i have a question?where i put the 8253 timer free pins out1 out2 gate clk.thanks 8051
We get different outputs at everytime we put the card. we just tried to get the data of an rfid reader into the ports of 8051. by using interupt and delays
