Khup chan madam..

[@temogolethoko7100]

Thank you 💞☺️ less than 2 minutes in and I got my solution,✅

[@tharunprathapan5883]

the video was 6 min long bro

[@atharvlohakare3935]

A nice sweet and simple explanation thanks for the help

Good explanation mam.

[@uzefsheikh7411]

Thank u so much ❤️

[@pavanchennur8411]

Gud explanation mam...do temperature program as soon as possible..

[@juhishah440]

So simple and easy

I am a beginner and I want to move a RC car forward, then stop when it bumps into a wall with sensor mounted on the car, then wait for few second and make a left. It couldn't compiled and I don't know how to add the sensor to the program. Awaiting your response Ma. Setb P0.0 Clr P0.1 acall delay setb P0.2 Clr P0.3

for alternate we take CPL or toggle?

[@sudhansumtripathy]

Hi, can you please share the MSP430 tutorials, it would be a great help. Thanks

[@rahulsomutte5886]

Nice mam

[@meenushalu3192]

Mam plz explain hcf program in 8051

[@quibler7]

what if i want a delay of 1 microsecond ?

[@naveencherry5767]

Yaa evn same doubt Please tell me

[@naveencherry5767]

What if I want a delay of 1 m/s

Why DBFFh? If your schematic uses Quarz with 11,0592MHz, and µC is in mode, when it takes 12 pulses pro Machine Cycle, it makes 1 Machine Cycle 1,085069µs long. You need (in this video) 10ms. Let's count how much Machine Cycles 10 ms takes: 1 MachCycle = 1,085069µs x MachCycles = 10ms x = 10ms/1,085069µs=9216 Machine Cycles. The Counter 0 counts upwards and resets istself at 2^16=65536. That means, in order to count to top and reset, the counter should start from 65535-9216=56319d. If you convert this decimal to hex, you'll get yout DBFFh, as in Video. That means, when your schematic uses other Quarz (10Mhz, 12MHz or 14MHz), you need to calculate value of the counter for that Quarz. Thanks for the great work, and for keeping it simple.

Thankyou you bro u cleared my doubt

For one led to blink continuously what to do....

While writing the main program : you have written 0FF instead of FFH so please correct it mam

[@StudyMicrocontrollers]

If data starts with character you should write 0 before starting character so that assembler will not confused between data and instructions. It is a rule. You should write 0FFH
