PsychoPy 3.2 also adds USB2TTL8 support to the Parallel out Builder Component, removing the need to use custom code to write to a USB2TTL8 device. Simply select "USB2TTL8" from the component's Port address and the first detected USB2TTL8 is used. Happy Days indeed!

Currently building the 3.2.0 release, with notably better timing, including a new faster sound engine built on PsychPortAudio. Happy days!

I forgot to tweet that this study involved a LOT of responses by a @BlackBoxToolKit actuator on a @labhackers millikey response box.

I can confirm both devices are happy to run to at least 1/2 million presses (only about 115,000 of which made it into the final paper)

LabHackers Device Manager version 1.5.0 is now available for download. https://t.co/PQChazV7lO

Users of the MilliKey LH-8 can now assign a modifier key to any two of the eight response buttons. Prior to version 1.5 buttons 7 and 8 were always mapped to a modifier key.

PsychoPy 3.2.4 is now out. https://t.co/KuKfqHNTPy

Especially important for mitigating Microsoft's new gamma-setting bug on Win10 update 1903

[LabHackers Research Equipment @labhackers]

LabHackers Device Manager version 1.4.0 is now available for download. https://t.co/zYANyG8gw4

This is a maintenance release that fixes several minor issues, including updating MilliKey MH \ LH button colors in the application and device memory.

Have a great weekend.

Nice! The new #USB2TTL8 integration looks great. You can use the SET_TTL action to write to, or the TTL_INPUT trigger to read from, a USB2TTL8 device. Handy for experiments that require access to digital i/o and there is no parallel port available. https://t.co/Ei7GB2iRzX

Experiment Builder 2.2.1 is now available on the support forum- updates include enhanced EEG integration, support for generic serial port devices, a new blink trigger and more: https://t.co/Yq5M6mbARy #EyeLink

Tested stimulus onset timing of macOS using a #MilliKey DeLux light sensor and @PsychoPy script. macOS 10.13.6 (+?) seems to add one frame delay to actual vs reported stimulus onset times. Anyone know of a fix?

Tested Windows 10 display timing using a #MilliKey Delux light sensor and a @PsychoPy script. Looks like the Windows 10 Display Scaling setting must be set to 100% or an extra 1 frame delay is added. Anyone else seeing this; anyone care? ;)

@dvbridges @openpsycho Great news. Please let us know how it goes and if you have any questions.

[LabHackers Research Equipment @labhackers]

@psychopy Would be interesting to look at the difference between the 'time stamp error' and the 'delay' of a event when using new Keyboard or iohub.
I think they will be different: event delay > time stamp error, where delay = time getKeys() returns event minus actual event time.

[LabHackers Research Equipment @labhackers]

Time stamping accuracy of the PsychoPy3 keyboard.Keyboard class being developed looks great on Windows, Linux, and even macOS. ;) Nice!
Tested using a 1000 Hz #MilliKey response box. Check out https://t.co/5TEOyCj3yN for more details.

[LabHackers Research Equipment @labhackers]

@psychopy Extra amazing for macOS IMO, as tests were run on a 2 core macmini circa 2012.

[LabHackers Research Equipment @labhackers]

@psychopy That is correct, the MilliKey timing procedure / results can only be generalized to other 1000 Hz USB keyboards & response devices that also have a known, fixed, 0 msec keypress debounce interval.

[LabHackers Research Equipment @labhackers]

@psychopy These are uncorrected numbers, so yes these delays are overestimated by ~ 0.3 msec on average. Do you think it better to subtract this from reported numbers or keep them uncorrected? Given it is a fraction of a msec, may as well just keep it in was my thinking. Opinions?
