HI, I want to use this USBASP,
**broken link removed** to program my 8051 (AT89S52) but I do not know where to begin..
I'd really appreciate if someone could walk me through the process.
Hi Jigar,
Hope you are keeping well. Thanks for the attachment.
I tried implementing the circuit but my values of RPM are not constant. It keeps fluctuating and at times go to -ve. I'm still working on it and Ill post everything I did after successful implementation.
Could you please tell me...
Will sure do Jigar, Thanks for all the help!!!
I'll implement the circuit and do everything you've advised me to do. This will take a day or two so I'll get back to you if the problem persist. PLEASE DON'T DISAPPEAR ON ME. :)
Thanks you!!!
you are a savior Jigr!
OK, I took your advice and amended my code as you advised me to do. I added the RPM calculation and LCD display as-well. I've messaged you the whole code
separately.
I tested the LCD bit of the code on Proteus software and it works but couldn't find IR components to test...
Hey Jigr,
Thanks for your prompt response.
Basically, I'm trying to count number of pulses in 1 second. that is number of 5 volts when beam breaks by blades.
total pulses=counts in 1 second / 3 would give me total revolutions in 1 second.
Multiplying that by 60 would give me RPM. I wanna keep...
Thanks you for your prompt response. I took you advice into consideration. umm basically I tried something different to calculate the RPM. here is my piece of code commented for better understanding. Could you please go through it and tell me if I've implemented it right and if it makes any...
Basically, there are three blades attached to the hub. I'm trying to use beam breaking method i.e. a pulse is recorded when beam breaks. the steps that I want to implement in my code to achieve my goals are;
1) Measure the time (x) between 1st and 2nd cut. this would be (1/3rd) of period of one...
