awesome
Giờ còn dùng PIC ko bác 😂
how often do you guys setup gates at Baylands?
Hi. This is not my track. The group that set this up seems to come every Sunday.

Hello Khoa. Do you still have osciloscope hitachi v1565?I have got the same osciloscope and I have a problem to measure single transient signal on it. Did you try to measure single transient signal? Best regards
How was this accomplished?
Can I get the code please. Thanks ❤.
Bạn ơi. 2 con IC kia là 2 con IC gì vậy ạ?
Hello brother, please send the code for this circuit

jean meeus?
What toolbox did you used?
Hi .. how to train end effector position to all accessible point using supervised learning using matlab .. please provide a link
I have absolutely no clues on what you r doing but here i am hahaa.
What device are you you holding? Looks like a WiFi pcb.
It's Wemos D1 mini (ESP8266-12E)
yo tMBIEN NECESITO EL CODIGO PARA MI PROYECTO SE LO AGRADECERIA MUCHO .
Speak fuck !
Great job, can you share the source code or the paper tutorial?

Hi Khoa Lam, Thanks for the is great video. You said the is an emulation by PIC MCU, does that mean the time data...etc is not coming from a real GPS receiver?
Serious Scandisk flashback. :) I'm considering 3560 for my home network, too.
Its quite silly video, you have shown that this scope is able to decode SPI. We knew that from the manual already. If you make a video , you should show HOW can we do that, that would be much more informative.
Sir, My name is Ramadani Bima from Indonesia. I have a problem with my Thesis I can't to pharse a date from nmea 0183. Can you help me to solve the problem?
con PIC32MX110F016b bạn mua ở đâu vậy bạn. .. tôi ở hcm
EDGE Spartan 6 FPGA Development Board got on-board ESP-12F WiFi module. Example VHDL Code provided with the EDGE board demonstrate Temperature monitoring through Cloud storage IoT Application.
Hi Khoa Lam just to be clear, the only needed to run the simulation is the robotic toolbox. How have you train the network? have you been using matlab then as well or have you been using something else. Br Marcus
Hi Marcus The purpose of the robotic toolbox was to give a nice visualization of my DH parameter table. The neural network was created and trained using Matlab. The data were created by using 3 for loops. The loops went through all acceptable angles for three joints and generated every possible position of the end effector from those angles using forward kinematics. The network was then fed the end effector positions and trained to output the angles (supervised learning). I hope my answer is helpful. Let me know if you have any other question.
But how?
Thanks, that was extremely helpful!
Hello! I am very experimented on PICs but new on NEO 6M. I am going to do a project which only needs a precise time. What tutorials do you reccomend me which you consider very usefull for this? Thanks
Hi. I don't have a specific tutorial to recommend, but I can give you the basic working principles of GPS breakout boards. The interface that these boards use is usually UART at 9600 baud by default. The module will take care of interpreting the data from the GPS satellites for you. The output GPS data and UTC time are sent in a series of characters called NMEA sentences. You can get the coordinates, elevation, and time (to the nearest second) easily by parsing the NMEA. www.gpsinformation.org/dale/nmea.htm
What accuracy do you get? To the nearest second? Millisecond? Microsecond?
It is accurate to the nearest second.
i am having this error: Info: ******************************************************************* Info: Running Quartus Prime Analysis & Synthesis Info: Version 16.0.0 Build 211 04/27/2016 SJ Lite Edition Info: Processing started: Tue Dec 27 18:26:42 2016 Info: Command: quartus_map --read_settings_files=on --write_settings_files=off ledblinker -c ledblinker Warning (18236): Number of processors has not been specified which may cause overloading on shared machines.

I believe that the error is due to undefined top level entity for the project. Error (12007): Top-level design entity "ledblinker" is undefined To solve this, just set the .vhd file contain the VHDL code for the LED blinker as top-level entity by right clicking it in Project Navigator and select "Set as Top-level Entity"
Hi, I keep getting this error: Error (12007): Top-level design entity "LED-02" is undefined I saw your comment above to set it as Top-Level Entity, but that did not change anything so can't get past it. Thanks.
Looks like I found the answer to my problem. I named the file as LED-02, and it is that dash(-) that caused the problem in the code when referenced. Changed it to an Underscore (_) and that fixed it (this is to change the name of the file and the reference in the code).
hi how to masure servo size
Can you send me all the verilog code for ESP8266 ??? arielfelixiii@gmail.com
Hi, It is just a Nios2 cpu attempting to parse the AT commands of the ESP8266. I didn't write any verilog for that.
Khoa Lam Where I can get verilog codes for the module???
can u show us the sketch, please!
Hello, mình có một vài thắc mắc trong khi sử dụng Quartus, Bạn Khoa Lam có thể cho mình xin email để trao đổi được không? Thank!

Hi, Nice work, I'm on a similar project, can we talk in private I need some help. ayoubel__@hotmail.fr Thks.
It has been a long time since I did this to test the concept, and I don't have the code for it anymore
can you give me the code in c?
No, I don't follow any tutorial for this. I simply read from UART1 and relay to UART2.
do you have a link to show how you did this?
I used Qsys to creat a customed Nios II MCU with a UART module to talk to the esp8266.
+Soós Levente I only used Qsys to create the custom Nios II microcontroller(no VHDL involved). The rest is done in C.
thank you! best wishes!
@lamkhoasajuuk do you still have this bemicro max 10 board? are you willing to sell it?
Did you use VHDL for this?... can you share it? Thanks
Thanks for sharing Have you schematic for Bipolar stepper motor driver morbus34@hotmail.com
IT WORKS!! Homemade driver everybody
which algorithm was used to calculate the sun's position?
RUclips won't let me post the link, so you can find the link in the video description. I include the code there, the SLAVE just need to match MASTER CKP and CKE in order to receive.
I used C, and assembly. They can coexist. On page 91 of the PIC16F88 datasheet, there is a diagram that explain what happen when you set CKE and CKP. On how to set CKP, you will only need to worry about transmit, the receive will just work if the transmit works. When CKP = 0, the transmit happen, when the clock is HIGH, when it is HIGH, it will send whatever the state of SDO pin to the SPI receiver. The CKE determine when the transmission will occur when the clock is from idle to active.
