| 10:44.07 | x29a | Tokemi: hi |
| 10:45.26 | x29a | Tokemi: http://opensimpad.org/index.php/Hardware_Details#1_Serial_Connector is that what your looking for? |
| 11:04.27 | Tokemi | x29a: well I already found that one, and I tried to connect it as specified there but, after resetting I only see "PBL V2.4 20.07.2001 |
| 11:04.28 | Tokemi | Booting..." followed by alot of question marks in the terminal |
| 11:05.05 | x29a | did you build your own cable? |
| 11:06.10 | Tokemi | yeah, I don't have a cable with the connector so I soldered them on directly on the connector |
| 11:07.01 | x29a | do you have the right levels? |
| 11:07.04 | x29a | i think its 3.3v? |
| 11:07.27 | x29a | im actually out of the simpad business, so im just guessing |
| 11:08.16 | Tokemi | aah, well they should be 12v according to the pinout on the site |
| 11:09.35 | Tokemi | otherwise I probably should have fried the port |
| 11:11.55 | x29a | defently not 12V |
| 11:11.59 | x29a | if, then vcc is 12V |
| 11:12.05 | x29a | but not the levels |
| 11:12.14 | x29a | i think there is a max232 behind the connector or? |
| 11:12.18 | x29a | 3.3.V or 5V |
| 11:12.26 | x29a | but 12V would be rather unusual |
| 11:18.19 | Tokemi | hmm I thought the rs232 port of a PC uses 12V levels |
| 11:20.43 | x29a | im not sure, but that seems a bit much to me |
| 11:20.46 | x29a | but again, just guessing |
| 11:20.58 | x29a | and since you still get some information, it seems to somehow work |
| 11:21.25 | x29a | do you have flowcontrol, all bits and speed etc. correct? |
| 11:21.28 | Tokemi | yeah |
| 11:22.22 | Tokemi | I don't really understand why only the first part seems to come over intact and the rest isn't |
| 11:54.02 | Tokemi | thanks for thinking along though :) |
| 13:23.27 | Tokemi | this is the output that I get : http://pastebin.com/m1fef4707 |
| 13:23.47 | Tokemi | the stream ends with a smiley face |
| 13:39.54 | x29a | how ironical |
| 13:40.03 | Tokemi | indeed ;) |
| 13:41.06 | x29a | the pastebin somehow shows some control-signs |
| 13:41.20 | x29a | it must be workin, since the beginning is fine |
| 13:41.30 | Tokemi | thats what I thought aswell |
| 13:41.31 | x29a | maybe broke your bootloader? |
| 13:44.05 | Tokemi | was my first bet aswell, but I have tried re-uploading the standard siemens bootloader twice |
| 13:49.27 | x29a | via jtag? |
| 13:49.30 | x29a | and verified? |
| 13:49.44 | Tokemi | yeah, had no errors |
| 13:50.40 | cyberdeck | hi! i just lurked your conversation. |
| 13:51.06 | Tokemi | hiya |
| 13:51.07 | cyberdeck | RS232 has a 12V level on the cable side. |
| 13:51.43 | cyberdeck | the data side at the max323 is 5V/3,3V compatible. |
| 13:52.01 | Tokemi | so it does need a level converter? |
| 13:52.34 | cyberdeck | the max323 acts as an level converter. |
| 13:52.46 | cyberdeck | u need a bunch of condensator soldered to it. |
| 13:53.35 | x29a | i gladly hand over to cyberdeck |
| 13:53.41 | x29a | ;) |
| 13:54.55 | Tokemi | so a connection between the serial port of the simpad and the pc doesn't require a level converter? |
| 13:55.08 | Tokemi | thanks for your help though x29a |
| 13:55.54 | cyberdeck | I don't know the serial port at the simpad side. give me a second I'll take a look at the wiki. |
| 13:57.04 | cyberdeck | yeah. it should work. |
| 13:57.16 | cyberdeck | To confuse u a little bit more: |
| 13:57.49 | cyberdeck | RS232 standard requires to have transmitters with -12V/12V. |
| 13:57.56 | cyberdeck | same goes for the receivers. |
| 13:58.21 | cyberdeck | but the standard also states that a receiver should detect a valid signal down to -3V/3V. |
| 13:59.05 | cyberdeck | so even if the simpad sends data with +5V/-5V on the TD/RD/... lines ur pc should read it. |
| 13:59.47 | cyberdeck | ok? sorry for the bad english ... |
| 14:00.25 | Tokemi | yes I understand you :) |
| 14:01.14 | cyberdeck | I'm just wondering if u bricked ur simpad? |
| 14:01.38 | Tokemi | and my pc seems to be able to read at least a few bytes that are send over but after that its all weird characters |
| 14:02.58 | Tokemi | could be, but the bootloader uploaded without errors |
| 14:07.26 | cyberdeck | sounds like to much noise while sending/receiving the data. RS232 has about 5% tolerance for the BAUD rate. |
| 14:07.38 | cyberdeck | Did u enable / disable hardware handshake? |
| 14:08.00 | Tokemi | yeah, hardware handshake is enabled |
| 14:08.34 | cyberdeck | k. then it should work out-of-the-box. |
| 14:13.24 | Tokemi | wish it did, thanks for you help though:) |
