Hi in my video I said that if the LED is white colour then it is "ON". This is incorrect. When the LED is white it is "OFF". I apologize for my mistake.
What you meant to say was that a white or turned-off LED indicates a 1 or a high on port output because LEDs are connected between positive supply rail and the output pins, meaning there is a voltage across them (they're turned on) when outputs are zero. In other words, logic 1 turns LED off, logic 0 turns LED on.
@@vooiyap Thank YOU for making these great, helpful videos! I listened to the relevant part in your video once again, and you did NOT make a mistake. At 9:48 you said: "A white LED means logic 1. Any other color means logic 0." and that was correct.
I'm using this program. Newcomers tend to focus on C language, but I find writing assembly code enjoyable. I'll convert it to hex and then load the program onto a CH551 or CH552 IC.
New subscriber and very interesting this topic. How could I show on the 7-segment display the result of pressing a certain switch? When pressing the first switch, "1" is shown and when pressing the next switch, 1 is deleted from the display and changes to 2?
Hi sorry for the very late response. In answer to your question, you need to display the second digit in the same location as the first one. I hope that answer your question.
Hi, professor, I have a question about the line of the text "time: - instruction: " what are the meaning of time and instruction? My instruction is running to 1460 now. My instruction does not run as fast as showing in the video. Also, as you made the modification in the comment, white means off (off == 0), then we put 00001111 and it should be white white white white color color color color?
Please check your System Clock (top left hand corner) is set 12 MHz and "Update Freq" is set to 10000. Regarding the LEDs, color LED is ON (logic 1), and white LED is OFF (logic 0).
@@vooiyap Thank you so much for explaining my problems. My instruction runs pretty fast after I set "Update Freq" is set to 10000. Also because the value is 00001111, so from 0 to 7 it should be off off off off off on on on on, then it should be color color color color white white white white in led.

Hi, professor, because I cannot change LCD E to P3.1, LCD RS P3.3(which is what we suppose to do for our assignment due tonight dealing with motor spin), as one of my friends suggested to me, I delete it and reinstall them again. Right now, it says "Java launch failure". (I am a mac user by the way) I do not know if you have any idea? I apologize if this is a pretty complicated problem, and you can tell me if you know. Thank you so much!
Try using the Dynamic Interface (DI) Panel - remap the peripherals. Link:www.google.com/search?q=EdSim51+dynamic+interface+DI&oq=EdSim51+dynamic+interface+DI&aqs=chrome..69i57.14349j0j15&sourceid=chrome&ie=UTF-8
Hi the assembler that you used should have an option that generates the hex file. With Keil IDE go the Project folder - Target folder - right click on the Target folder - select Options for Target - select Output tab - select Create Hex File opotion. Hope that helps.
@@RepairRadioLab Hi it will be similar with any assembler. There is usually an option to create a hex file. May I know which assembler or IDE you are using?
What do you mean? If you're talking about the LED output, 1 would be on the right. The LEDs are hooked up between the positive supply rail and logic outputs, meaning that they turn on when the logic output is 0 (zero), and off when logic output is 1 (it's counter-intuitive when learning, but that's how it is).

Can I start with Assembly 8051 or Assembly X86 as a first assembly language ?
Hi you can start with any assembler langauge.
Wonderfully explained sir !
Thank you for your kind comments. It's appreciated.
Hello, Do you know any simulator for P80C528? Thanks, Great Videos
Sorry, I don't know any simulator for P80C528.
Hi. Why we have to copy the value to ACC first? Why we can not copy the value into the another port directly? Can you explain? Thank you.
Yes, you can copy the value or data directly to the port.
