Hello and welcome to my channel. My name is Vooi. I am a retired lecturer and my specialization is embedded systems. I am making a series of videos that are designed to help you understand embedded systems. The plan is, for a start, is to make a series of videos focusing on some fundamental knowledge. It is my hope these videos would lay a good foundation to understanding future videos related to embedded systems, especially, microcontrollers which are a key component of any embedded system. If you are interested in learning about embedded systems stay tuned to this channel.
Hello Vooi, thanks for your video's I really enjoy them and have been learning a lot. FYI. the link to download the source code in this video doesn't seem to work.
Hi, thank you for your comments. I am glad you like the video. I have updated the link to the code used. Please check it out. If you have problems accessing it please let me know.
@@vooiyap Yes I enjoy your library of videos a lot. I have been working in IT for over 30 years and you have clarified some fundamentals (about stacks amongst other things) that I have wondered about for years. In the interest of helping you 8051 Assembly Language Programming Playlist. (videos 13-15) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9hxhFqJWBZ8.html. Also, if its not to indiscreet I am curious about the origin of your first name and accent (feel free to reply in PM somewhere else). Thanks again for your work.
Interesting topic and videos. Thanks for sharing. I noticed the lessons in the playlists are ordered backward and automatically plays lesson 1 after finishing the 2. Thanks again 😊
How can I choose a button on the numeric keypad and when pressed this button the value on the display increases from 0 to 1 and so on up to 9 and so on until returns to 0 again And choose a button on the numeric keypad and when this button is pressed, the value on the 7-segment display decreases from 0 to 9 and so on until it returns to 0 again as if it were a loop but a button must be pressed for the value to increase and another button to lower the value on the 7-segment display Like an example: If I pressed number 1 on the keypad the value incrises on the display of 7 segments and if I pressed number 4 the value decreases on the display of 7 segments Can you help me ?? Because I have seen many videos but I can't do a code to this problem
Hello, thanks for the content. Can we light two lcd's at the same time. Viewing number 1 in led 1, viewing number 2 in led 2 at the same time. Being able to see 12 in the 7 segment leds
@@vooiyap thanks for the reply, i checked the code and in there led 1 displays 1 and then turns of, and then led 2 displays 2 and then turns off. i don't want that led 1 or led 2 gets turned off. What i exactly want is, can i see two leds lighting at the same time?
@@zekeriyyakoroglu3461 Hi, I regret to say that is the limitation of EdSim51 simulator. The technique should on real hardware. You could try Proteus Simulation software but I have no experience with Proteus.
@@vooiyap I was trying to find a way out how to do that since a few days for a school project, thats good to know that it is not possible. Thank you for the support.
@@zekeriyyakoroglu3461 Hi, I am glad to be of some assistance. You can contact me at the following email: vvy.eseducation@gmail.com should you require any help.
For anyone still want more info "This is called sequential logic and the scheduler use states to execute the task, the timer is what remind the processor to perform is job, so the timer is the controller, and the register i.e. the program counter is the state that let the controller know what state it's currently in and the next state to go to i.e. the next task."
Hi, thank you for your comments. At the moment I am focusing on the Cortex M4 assembly language. Please refer to the following videos that uses C: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1owPifxFPYI.html ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-YGMieAZyJ6Q.html I hope you will find what you need.
256*256*70 = 4587520 cycles. Arduino UNO uses 16000000 Hz Crystal so : 16000000/4587520 = 3.487 seconds. This should be blinking freq. But in video it seems like 500 ms. Why is it so ?
Hi, to calculate the duration of the delay generated by an ATmega328 microcontroller using a 16MHz crystal, we need to take into account the time taken by each instruction and the number of iterations of the loops. Write to me at the following email address and I will send you the details of how I would calculate the duration of the delay. My email address is: vvy.eseducation@gmail.com
Thank you Vooi. This video is very helpful. This is my first assembly program written on this board. For unknown reasons, the register R3 didn't change value to 0x95 when debugging at first. I rebuilt and downloaded the object file to the board. The problem fixed.
I'm learning a lot from your videos. ghemso created a group to watch his videos. But the link he sent me does not work and we have not yet been able to install EdSim51 and we would be very interested in having EdSim 51 installed to continue moving forward. I don't know if you can help me. Thank you so much. A greeting from Spain
@@vooiyapI have finally been able to install EdSim51. Now we will start practicing with it and learn all the possibilities it offers us. Maybe there is a tutorial that explains the functionalities of this software. Thanks a lot. We follow your videos which are great. Best regards from Spain.
Interrupts and the stack are fundamentally linked in the context of microcontroller operations. The stack is essential for handling interrupts efficiently and ensuring that the program can return to its normal execution flow after an interrupt service routine (ISR) has completed.
@@vooiyap hello, the Arduino folder is what i meant, its doesn't exist anywhere. But I already fixed it, I installed the new version of Arduino that's why its missing.
@@vooiyap my arduino folder exists, but it only have the libraries folder. i dont know why it doesnt have the others folders. i tried to install the IDE again, but nothing changed, do you know why this is happening? sorry if i said something wrong, im still learning english
im cannot build solutions , the error said : invalid redefinition of 'SIGNATURE_000' is it the problem , when i choose atmega328 at the begining project or what is the problem actually?
So helpful, thank you! I found your channel by looking for Arduino assembly videos but then realised that I need to learn a bit more about MCUs and registers, then understood from you what latches are and finally how everyting works together. Really helpful, thanks so much for your dedication!
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.
