Spinneret server html problem
Podion
Posts: 90
Hello,
I have a project, my project is to control the lights, doors, temperature and other things .. from anywhere in the world.
You can see the website http://108.171.79.7:5555/index.htm
I have a Proppeler as a client and a Spinneret as a server that communicates via two wire serial RX and TX to the client how control all.
The site works fine but I'd like to see all the states in the same web page. I tried several things but I think my problem is in the html code ... Look at the code and tell me what you think. What can I do to show all the states "On" or "Off" on the same page?

Revision History:
Version 1.0 - original file created as a high speed Prop to Prop
Version 1.1 - (03-29-2011) added routines to aid in handshaking
as well as data packet re-direction.

The Anatomy of the packet data:
When Sending (TX) You must indicate in the PacketHeader what address you want the
data to come from. Additionally the Dest Offset tells the receiver the amount of
offset in LONGs of where the data will be written on the receiver side. The Dest
Offset value overwrites the position of the Data Address prior to sending the first
Packet so that the Dest Offset value is sent rather than the Data Address.
The Data Command (Optional) is used to request a specific function from the receiver.
Note: The receiver must be programmed to know what to do with the command value.
Packet Size is also conveyed to the receiver, indicating how many packets the receiver
is to expect.
Note:
- Packet Size, counts as 1 packet itself, so if your packet data is 100 longs, then
the Packet Size should indicate 101.
- You must send at least 2 Packets for a valid transmission.
PacketHeader: 32-bit long
%ssssssssssssss_aaaaaaaaaaaaaa_cccc
└ Packet Size┘ └Data Address┘ │ │
14-Bits 14-Bits │ │
Data Command ; $0 - $E command to send to the receiver
4-Bits Note: $F is reserved to indicate Transmission is complete
- The data pin is only driven HIGH.
- A pull-down resistor of 330 Ohms on both the Server and the Client side of the data pin
keep the pin LOW.

Note: All resistors tied to Vss are 330 Ohm and are there to establish a transmission line
Note: All resistors between TX and RX are 100 Ohm and are there to current limit the I/O's in the chance
of a collision.
With round robin, the idea is that you have one buffer that propagated around and around inside the
round robin loop. To avoid any data collisions, all Propellers are capable of reading any location
within the buffer, however each Propeller has a specific (assigned by the programmer) location that
it can write to.
So in the Demo, there is a 1K long buffer (4K bytes). As an example Propeller 1 may only write to
locations 0 to 255. While Propeller 2 can write to locations 256 to 511. Propellers 3 & 4 depicted
as N because of the expandable nature of round robin would write to the remaining 512 to 1023 locations.

Revision History:
Version 1.0 - original file created as a high speed Prop to Prop
Version 1.1 - (03-29-2011) added routines to aid in handshaking
as well as data packet re-direction.
≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈≈
The Anatomy of the packet data:
When Receiving (RX) You must indicate in the PacketHeaderOut where you
want the received data to be stored.
Note: If TX sends a Destination offset value it will be added to the Data Address value
and the incomming data will be written starting at the new offset location.
The Data Ready Flag is automatically set in the RX function.
PacketHeaderOut: 32-bit long

After data has been received then PacketHeaderIn contains information from the
transmitter such as Packet Size, Dest Offset (This is the offset value applied to the local
data address), and a Command Packet that provides a way for the transmitter side to send
specific instructions to the receiver side.

- The data pin is only driven HIGH. This is similar to an open collector mode with a PNP drive transistor.
- A pull-down resistor of 330 Ohms on both the Server and the Client side of the data pin
keep the pin LOW.

'Packet Sync' detected by RX, RX is ready to receive data
Note: TX monitors the Sync detection from RX and if TX doesn't see the response
from RX, then the 'Packet Sync' is sent again until it does.
TX must send at least 2 packets in order to be a valid transmission.

Revision History:
Version 1.0 - original file created as a high speed Prop to Prop
Version 1.1 - (03-29-2011) added routines to aid in handshaking
as well as data packet re-direction.

The Anatomy of the packet data:
When Sending (TX) You must indicate in the PacketHeader what address you want the
data to come from. Additionally the Dest Offset tells the receiver the amount of
offset in LONGs of where the data will be written on the receiver side. The Dest
Offset value overwrites the position of the Data Address prior to sending the first
Packet so that the Dest Offset value is sent rather than the Data Address.
The Data Command (Optional) is used to request a specific function from the receiver.
Note: The receiver must be programmed to know what to do with the command value.
Packet Size is also conveyed to the receiver, indicating how many packets the receiver
is to expect.
Note:
- Packet Size, counts as 1 packet itself, so if your packet data is 100 longs, then
the Packet Size should indicate 101.
- You must send at least 2 Packets for a valid transmission.
PacketHeader: 32-bit long

- A pull-down resistor of 330 Ohms on both the Server and the Client side of the data pin
keep the pin LOW.
