Readout code

V1

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

http://www.physics.isu.edu/~tforest/DAQ/GEMReadout_V1495Source_Rev1_0.zip

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:
(0x80118000 - A32    0x90118000 - A24)

The v1495 library has the function below which when

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)
