Readout code

V1

The ZIP file below contains the HDL source code to download into the V1495

The ZIP file below contains the ROC library

http://www.physics.isu.edu/~tforest/DAQ/GEMReadout_VxWorkxSource_11_26_2008.zip

ROC lib

compile library

To compile the ROC library I executed the following command within the subdirectory containing the v1495.c file

ccppc  -fno-builtin -fno-for-scope -fstrength-reduce -mlongcall -mcpu=604 -DCPU=PPC604 -DVXWORKS -D_GNU_TOOL -DVXWORKSPPC -I/usr/local/coda/2.5/common/include/ -I../h -c -o v1495Lib.o -i v1495.c

load library onto the ROC

I then copies the library v1495Lib.o into my ROC library subdirectory which is where the ROC is pooing at boot up

/home/daq/CODA/ROClibs/libs

I loaded the library by hand by typing the following at the ROC console

-> ld < v1495Lib.o
value = 268430512 = 0xfffecb0

Setting address

The address pins on this module are not labeled so I adopted the convention of numbering them from left to right as I look from the front pannel.

400 px

Address
Pin	Setting
SW 3	3
SW 4	2
SW 7	1
SW 8	1

probing memory

I set the switches as follows

   sw3  sw4  sw7  sw8
    0    8    1    1


And the following is a printout of my board:

Download Firmware

To download the firmware to the USER FPGA area you need to pass the address which is 0x8000 below what the dial setting are

v1495firmware(0x90118000,"GEMReadout.rbf",0,0)
