Thank you so much for this video,PLease post more videos on the programming on keil software for 8051 microcontroller , or suggest me any reference books to learn more on embedded c programming
I have one doubte , unsigned char actually used for character type ,and here you gave assigned Interger value to x & y ,I am very Confused Can you explain what is logic behind of this ??
I'm surprised that there is no official tool / plugin for Stm32 IDE that allows you to simulate the processor for purposes of stepping thru and debug code. For the total beginner, any thoughts how Keil + proteus compares to the linux based QEMU?
Hello Sir, I am getting a error message "Cannot find model file LEDA.MDF".And also a 2nd error as "Simulation FAILED due to netlist linker error(s)". How can I solve those error? Software used are Proteus Professional 8 and Keil uVision5. Reply as soon as possible.
@@purvamhatre1621 I doing my assignment but getting some sort of problems in alternating blinking of LEDs even trying it 89 times but doesn't get run errors ajaataa hain
when i compile the program, i get errors 'p1': undefined identifier. i set p1 as unsinged char and the error went away. however when i play the hardware all LEDs turn on at the same time. what do you think the problem is? thank you
dude, i want to ask one question, iam doing same program to toggle led, but for port 0 led doesnt chase, but when i change port pin led start chasing, why port 0 doest working propoerly, even you can try in keil simulation reply as soon as possible
Hi Ajithem , Port 0 from 8051 , it is open drain port , you need to connect external pull up resistor to use as normal I/O pins. one end with Vcc and resistor other end connect with I/O . now you can drive any peripheral using Port 0.resistanance (4k to 10k). Thank you
P1 define the port to transfer data. 0X = it is syntax to write the code 00 = It is data that send to LED (If Use Common Cathode: all LED are off, If Use Common Anode: all LED are on)
can anyone help me. So many errors in proteus i don't know how to fix. cannot find model file "ITFMOD.MDF" cannot find model file "LEDA.MDF" missing interface model'At89' at U1 #p ...etc
Simulation FAILED due to fatal simulator errors. this is what I get when I simulate. Im using demonstration version proteus 8.5. I can view simulations of sample files n other circuits. but in this Im getting this message.please help
