i need to build a ladder program with this PLC (A1shCPU from mitsubishi) and use GX Developer v.8 as the software. if u can help me with the list of relay an timer simbols that i can use from this PLC, since i need a relay, timer to build this program.
and if you could help me, how should i...
well if you want to use a switch, than this switch used to connect the ground or to the power of each seven segment, so, to make it simple, even you actually give the same output to all of the three seven segment, if you only activated 1 sevent segment, you make an illusion as if you able to...
I only have two question for the code i just download from you,
1. why don't you describe the port for data Output when it's receive data?
2. can I download it to my MCU? my AT89S51?
by the way if don't reply again after this that means I already off. So I'm sorry, I really don't have any mean...
well if i use regular transmission use RS232 only, the program (above) it went well. I mean correct. I only found problem when I use the wireless comm use this paired IC (TLP and RLP 315Mhz)
hi embedded parter you quit good on describing the main progres of this operation, but the output is always full of noise so I can't tell which it is swhowin the data I send, with TLP or the noise. I use AT89S51 for recieve the data and Hyperterminal to send the data.
hi ctownsend, the character of "*" and "#" send first every time we want to recieve data. wich means the other data that is not the same as * and # will be rejected (the noise), but after the receiver receive the * and # charater, the next step is receive the data, that means the real data won't...
okay this question seems so stupid, i also embaressed to ask it, but i really need it. my capacitor value writen as "1U0J100" it is a square-look capactior. so anybody can tell me how much farad it is?
xcuse me. can any of you help me with read the capacitor code. i have a square-look cap with 1u0j100 writen on it. is it 1 nF? thx and sorry to ask it here.
don't pick subject thst sound cool but you can't handle. pick one that is as simple as possible that qualified enought to bring you to your graduation. but i you insist on this subject please at least use google to specified the question that we can answer.
use PWM that way you can control the speed of motor. define the variable, for example if you want to make 3 variant speed for your fan then define speed 1 as 30%, speed 2 as 65% and speed 3 as 100% of duty cycle.
i use TLP and RLP 315Mhz produced by laipac to send and receive serial data. the plan is i send data from my PC use hyperterminal on Comport 1, then comport 1 connect to RS232, RxOut connect to TLP tx pin, then the data should be receive by my RLP that connected to my MCU and the data displayed...
for this problem maybe you can add a procedure in the receiver program to eliminate the noise. for example, you can lomot the data that you receive will only the data that comes after 2 charachter like "*" and "#". so you make a filter to reduce the data that your receiver should display. after...
