Dangerous DSO part 5: Testing and conclusions

Friday, May 13th, 2011

It's the last day of our week-long Dangerous DSO adventure. Yesterday we simulated the analog front-end and found a few changes to test. First, we're going to increase the ADC buffer gain to 2. That should make vertical offset adjustment easier. Second, we're going to try a more refined input...

Monday, October 11th, 2010

Bus Pirate v4 is alive! Bus Pirate firmware v5.9 is running on the new Bus Pirate v4 hardware with direct PIC-based USB connection. It started out slow because USB support is hacked into replacements for the existing serial port functions, but the latest SVN version is working great. BPv4 doesn't...
