RC radio dibuat jadi RC kabel

[coyo]

yg paling sederhana yg link dr Pakdhe Suhu NF tadi:


yg ini juga bisa dimodif jd ppm decoder koq: viewtopic.php?f=121&t=14139

[coyo]

wah
klo Rx nya ga support, buat yg hobby elektronika bisa bikin sendiri "PPM-decoder", misalnya:
versi PIC: http://homepages.paradise.net.nz/bhabbott/decoder.html
versi Atmel:

....artinya suhu coyo bisa buatkan ?

' FUNCTIONAL DESCRIPTION

' Principle:
' Timer1 is configured as a counter. It is clocked with a clock of 1.0 MHz.
' This per clock a time of 1.0 microseconds elapses.
' The Timer1 causes two interrupts, namely OC1A and OC1B.

' OC1A is used to
' to identify a missing PPM signal. The value is set to RC_Timeout,
' and corresponds to a time of 50 milli-seconds. If during this time, no edges
' detected on the INT0 input, the interrupt is triggered and calls the routine _ISR_INT0.
' The timer is automatically reset to zero.

' OC1B is used to detect the start signal of a pulse train. The value for
' Compare1B is set to RC_Frame and corresponds to a time of 2.5 milli-seconds.
' If at this time no edge occurs, the interrupt occurs and the routine
' _ISR_OC1B called.

' The RC-sum signal (PPM) ICP1 the input is supplied. For each negative edge
' a ICP1 interrupt triggered.

' ICP1 Interrupt:
' In the ICP1 the Timer1 interrupt routine is set to 0 and increase the channel count by 1.
' Then the channel pulses are issued. Finally, will offer a status bits
' in the variable status flags (byte) set.

' If a start is detected, the channel counter (RC_ChannelNr) is set to 1.
' If no start signal is detected, the channel counter is incremented by 1. Thereafter, the
' selected channel (RC_ChannelNr) connected and the previously activated off.

' If more than 8 channels (PPM) are transmitted, the channel count is increased further.
' On the channel outputs but only a maximum of 8 channels are decoded.

' If less than 8 channels (PPM) are transmitted, the channel counter is displayed,
' And it will be produced at the outputs of any other stimulus.

= pake beberapa servo tester untuk gerakin : drive motor , diving plane , rudder dan camera .....
simple nya , dari handheld controller cuma perlu kabel isi 6 , 2 kabel untuk catudaya tester (kalo pake batere dari ROV) dan 4 kabel buat servo control. jumlah kabel bisa bertambah kalo buat kirim gambar video ke monitor diatas.

Pak. servo tester itu bisa untuk maju mundur esc ya? posisi tengah itu off, kemudian kanan maju, kiri reverse?
thanks buat masukannya..

[todiahmad]

Thanks masukannya om Coyo...
cuma lagi cari yg simpel he he...
kepikiran skrg pakai relay2nya mobil, tapi perlu 12 buah buat maju/mundur, kiri/kanan, atas / bawah

[NF]

knapa ga minta tolong sama suhu coyo saja ??

ESC r/c car uyg bisa reverse om, kalo ESC pesawat/hely gak ada yg bisa

Setuju suhu NF minta tolong suhu coyo saja buatkan yang penting maharnya sesuai he he he .........

[todiahmad]

knapa ga minta tolong sama suhu coyo saja ??

he he.. bisa juga sih. bukannya ga mau ( thanks ya om coyo ), masih mikirin mana yg paling simpel dan bisa dikuasai. sebel kan kalo rusak di tengah laut, tapi ga ngerti cara benerinnya?

Inget pernah ada seminar atau apa gitu, ttg building automation system ( BAS ). Ada vendor dari jerman dan jepang. Kalau jepang, partnya hrs beli di dealer dia. Total investasi emang lebih murah, tapi partnya khusus, jadi ya mahal.. sedangkan yg jerman, investasi lebih mahal, tapi banyak parts nya yang ada di pasar kenari ( kalo yg dijkt pasti ngerti pasar apa itu ), dgn part number yg sama.
Yg ngomongnya si bule jerman langsung, tau juga dia pasar kenari
