pyBoard_LED_stimulator
Full-field LED stimulator running on the pyBoard using MicroPython.
First test version, with 4 LEDs connected to pins X1 to X4, a synchronization signal ("trigger") provided at pin Y11, and a fast, external "blanking" signal (high == LEDs off) received at pin Y10.
Release Notes
-
2017-03-10 - First test version Tested with a 500 Hz (0.4 ms off-time) blanking signal provided by an Arduino: With the current code, the blanking is not reliable; the LEDs are blanked for longer periods at irregular intervals. Possibly due to the garbage collector running in the background. Turning off garbage collection caused memory problems; these can probably be addressed by removing all dynamic memory allocations, but this also removes advantages of using Python (vs. for example C on an Arduino).
