Determining why Vdetcom is shorting out.<br />
<br />
Matt created a wiki account .<br />
<br />
No shorts found in wiring harness or across card. <br />
<br />
Begin work to get DSP code running on Mac or Windows 7.<br />
<br />
'''2011 June:'''<br />
<br />
Continue work on DSP code as it is needed for further debugging of Vdetcom short.<br />
<br />
Information for updating the tim script for use under Wine can be found here: [[media: WineScript.pdf]] in an email from Bob Leach.<br />

<br />
Wine + DSP Assembler installation on lab computer.<br />
Fedora Version Running: Fedora release 7 (Moonshine)<br />
cmd: more /etc/redhat-release<br />
<br />
<br />
<br />
Install Wine: <br />
cmd: yum install wine<br />
Wine installed.<br />
<br />
DSP Versions:<br />
ASM Class 56300<br />
DSP Gen III<br />
<br />
<br />
Debugging Process:<br />
Used chmod -x to make the script Wine_tim executable.<br />
Throws 2 errors. 1. :Bad Interpreter 2. No such file or directory.<br />
Fixed with dos2unix Wine_tim.<br />
<br />
DSP SUCCESS!<br />
DSP compiled with no errors... No testing of if the tim file works yet.<br />
Wine_tim is the script for compiling the dsp code.<br />
Wine_tim is found in /home/matt/Desktop/DSP/<br />
Command to compile is ./Wine_tim<br />
timboot.asm, timIRmisc.asm, and timmisc.asm must be present in directory for compiler to work.<br />
<br />
DSP Check.<br />
New timing files have been checked via diff command. Files are identical except that in some cases an additional digit<br />
has been added to the ends of some values. These digits come after the decimal place and are always zero so no change<br />
in voltage should be observed.<br />
<br />
VSS1 pin # 19 at DB37 reads -1V as listed in CRC744.waveforms.<br />
VSS2 pin # 17 at DB37 reads -1V as listed in CRC744.waveforms.<br />
VDDCL pin # 16 at DB37 reads -1.7V as listed.<br />
VDDUC pin # 33 at DB37 reads -3.5V as listed.<br />
VRSTUC pin # 14 at DB37 reads -3.5V as listed.<br />
VDDOUT pin # 32 at DB37 reads -1.2V as listed.<br />
VOFFSET pin # 15 at DB37 reads -1.5V as listed.<br />
VGG1 pin # 13 at DB37 reads -3V as listed.<br />
VGG2 pin #31 at DB37 reads 0V as listed.<br />
VSSSCANF pin # 12 at DB37 reads -1V as listed.<br />
VSSSCANS pin # 11 at DB37 reads -1V as listed.<br />
VDET pin # 29 at DB37 reads 0V as expected (the short).<br />
<br />
NOTE: Wine_tim is only executable as superuser at this point.<br />
<br />
<br />
'''2011 July:'''<br />
<br />
VDET short found. A split in the insulator around the insulator has cracked such that when bent, the conductor is exposed and<br />
causes the short. The wire is being replaced.<br />
The other wires of the same material are being checked and replaced if necesary.<br />
<br />
AT LEAST 2 OTHER WIRES IN THE FEED THROUGH ARE IN DANGEROUS CONDITION. THE WIRE IS VERY HEAVY AND STIFF AND SHOWS EVIDENCE OF A CREASE<br />
CAUSED PERHAPS BY BEING CAUGHT IN THE HEAT SINK. FOR THE SAFETY OF THE ELECTRONICS IT IS NECESSARY TO REPLACE SEVERAL, IF NOT ALL<br />
OF THE CONSTANTIN WIRES THAT WERE SOLDERED BY THE PEOPLE WHO INSTALLED THE COAX INTO THE WIRE HARNESS.</div>141.211.198.225https://monnier.astro.lsa.umich.edu/research/index.php?title=NASACAM:Anderson_Notes&diff=2344NASACAM:Anderson Notes2011-07-07T15:23:43Z<p>141.211.198.225: </p>
