- HV Pulsers work!
- I got nice echoes day before yesterday
- Got images with a probe yesterday
- Acquisitions rock at 32 and 64Msps avec ce binary!
- Now working on 8bits. Still issues on 16 bit transfers.
-
Can read some values now from MATTY_20180218.bin
-
and corresponding notebook -- even with a piezo on !
-
Testing SPI
- matty20180211_bitmap.bin seems to work -- see the notebook
- All registers can be written
Picture needed on the PonPoff hack on the U118, U131, U134 -- soldered reversely
Now the DAC seems to work, still no SPI
When issuing 0xAA, 0xEB, 0X01, I see what I expect to see... but there's no CS going back high after each byte.
Seems to occur.. https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=73323
DAC SPI seems off
Want to have a notebook running on board RPi to access the SPI dev
apt-get -y install python2.7 python-pip python-dev apt-get -y install ipython ipython-notebook pip install jupyter
The Notebook server listens on localhost by default. If you want it to be visible to all machines on your LAN, simply instruct it to listen on all interfaces:
jupyter notebook --ip='*'
- Done! With the code, it works. I just need to rmmod ftdi_sio and usbserial before flashing with programmer from usb.
- CDONE is on, weak LED corresponds to 64Mhz signal (same in the dark)
- See this repo which contains the hex/bin files, the ice40.xcf for as the programmer save, and prog to start the programmer without cumbersome kernel modules.
- Still having issues with the FTDI-SPI pinouts
- Clock is soldered again! And FTDI device magically appears in lsmod.
Investigation showed no connection through USB.. a ftdi issue. Powers were OK.. but still nothing.
So what? Clock!!
I unfortunately destroyed the 12MHz clock.. well that's it =) I'll be waiting for the new one from digikey.
The clock has to be rotated by 90°
Let's have a first peek
This has reached a couple of days ago =)
Looks good - ice40 and ram look good. The high-level pulser footprint seems reversed. The 3.3V is on, 5V level looks good, seems good!
