| + | ====== Troubleshooting ====== | ||
| + | |||
| + | This section will be added to as new problems are reported on the sourceforge help forum. | ||
| + | |||
| + | Symptoms: | ||
| + | |||
| + | jAER is running and a DVS is plugged in. Either there are no spikes coming out, or there are some spikes but they don't make sense. | ||
| + | |||
| + | Possible solutions: | ||
| + | |||
| + | 1) Check that all filters are disabled. | ||
| + | 2) Check that the lens aperture is open. | ||
