Hi, I do not know try you are getting this error but try this link for the file: drive.google.com/file/d/1XqGDQt50_Th77DPlTh0zPFkW_1ckOhKA/view?usp=sharing Let me know if it works.
@@vooiyap I'm currently facing a problem with "invalid device signature", may I know what could be the problem? My led did light up but it doesn't blink
Thank you for this series. Very helpful for to put a beginner on track. Can you please explain the needed of the 10u capacitor in parallel with the switch between +5V and R1?
I am glad that is useful to you. The purpose of the capacitor and the resistor is to perform an auto-reset on powering up the microcontroller. I hope that helps.
Facing a weird issue... when the capacitors to the crystal oscillator are connected the 8051 does not work... whereas the capacitors when removed the microcontroller runs smoothly...
Hi sorry for the late response. I do not know of any easy way to lock AT89S525. The following website might provide some clues: www.engineersgarage.com/at89s51-52-isp-programmer-lock-bits-setting/
Hello Sir, Is C programming necessary to write programs for these boards or we can use assembly language also? If not, then are there boards other than Arduino which allow assembly language programming? Please help
I have sent a comment about 4 days back, but no reply is received. cmd type is working fine, but gui method I could not make it. The momory is exceeding 2kb of flash. Will it still run since keil says max. flash size for demo version is 2kb ? pl. camment on this. con't we send you my mail id and mob.# in this comment?
Hi I am apologize for not responding earlier. I have been quite busy and I have not check my channel. It will be good if you can send me more details to this email: vvy.eseducation@gmail.com.
I am glad you like it and I hope you find the videao useful. By the way, I have build a shield for the programmer and I will put it up in the next video.
A Fuse Bit configures the Operational Mode/Functional Mode of the microcontroller (MCU) at the time of the 1st power up initialization when no instruction has yet been executed. The state of a fuse bit must be altered before “Programming the Lock Bits” associated with read/write protections of Flash Memory and EEPROM Memory of the MCU. Once, the lock bits are programmed, the state of the fuse bit cannot be changed. The option that is left is to erase the chip (chip erase brings the lock bits back to their default values) and then set the fuse bits.@@April2023-fb6pf
Hi, thank you for your question. Vin is located on the Arduino Uno board - just above the ANALOG IN pins. However, I am not sure which VREF pin you are refering to. By the way, VREF and Vin are not used in the project.
@@vooiyap I'm making a control led with a potentiometer. where can i wire the potentiometer in this microcontroller? my arduino project says wire to Vref. thanks for the quick answer
@@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
