I tried running pixeltime.ino on my \"P10 (3535) 16x32 - 4S\" display hooked up to a amica NodeMCU, but it looks strange.\r\nThe 4 in the name made me think the display might be a 1/4 row scan type, so that's how I wired it up according to your instructions. It seems all the leds can light up, but the pattern is somehow mixed up. I attach a video of the pattern_test.ino running. \r\nI tried to add a line display.setScanPattern(ZIGZAG) after display.begin(4) to test whether it changes anything, but I get a compiling error: 'class PxMATRIX' has no member named 'setScanPattern'.\r\n\r\nAny ideas what I might be doing wrong?\r\n\r\nCheers,\r\nLucas\r\n\r\ntest pattern: [LINK](https://kth.box.com/v/pixeltime)\r\n"},"comment":{"url":"https://api.github.com/repos/2dom/PxMatrix/issues/comments/392333503","html_url":"https://github.com/2dom/PxMatrix/issues/14#issuecomment-392333503","issue_url":"https://api.github.com/repos/2dom/PxMatrix/issues/14","id":392333503,"user":{"login":"Cyberfly100","id":28017534,"avatar_url":"https://avatars1.githubusercontent.com/u/28017534?v=4","gravatar_id":"","url":"https://api.github.com/users/Cyberfly100","html_url":"https://github.com/Cyberfly100","followers_url":"https://api.github.com/users/Cyberfly100/followers","following_url":"https://api.github.com/users/Cyberfly100/following{/other_user}","gists_url":"https://api.github.com/users/Cyberfly100/gists{/gist_id}","starred_url":"https://api.github.com/users/Cyberfly100/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Cyberfly100/subscriptions","organizations_url":"https://api.github.com/users/Cyberfly100/orgs","repos_url":"https://api.github.com/users/Cyberfly100/repos","events_url":"https://api.github.com/users/Cyberfly100/events{/privacy}","received_events_url":"https://api.github.com/users/Cyberfly100/received_events","type":"User","site_admin":false},"created_at":"2018-05-27T14:06:51Z","updated_at":"2018-05-27T14:06:51Z","author_association":"NONE","body":"Alright! Now the setScanPattern and setMuxPattern commands work. Thanks for patiently guiding me there :)\r\nAfter trying around a bit, it seems STRAIGHT and ZAGGIZ give the best result on the pixeltime.ino but it's still not quite working, I think (see pictures).\r\nI thought with a 1/4 row scan display I would not be using the C input. Should I still use the setup line like this: PxMATRIX display(32,16,P_LAT, P_OE,P_A,P_B,P_C); ?\r\n\r\n I uploaded another video of the test_pattern.ino with \r\n  display.begin(4);\r\n  display.setScanPattern(ZAGGIZ);\r\n  display.setMuxPattern(STRAIGHT);\r\n\r\ntestpattern: [LINK](https://kth.box.com/v/pixeltimeSTRAIGHTZAGGIZ)\r\n\r\n![6](https://user-images.githubusercontent.com/28017534/40586820-be581fe8-61c7-11e8-8ceb-4b4fb0a7a413.jpg)\r\n![1](https://user-images.githubusercontent.com/28017534/40586821-be74dc0a-61c7-11e8-81a3-75c9a01b04fe.jpg)\r\n![2](https://user-images.githubusercontent.com/28017534/40586822-be8e8ccc-61c7-11e8-925a-0ff8a10bdc75.jpg)\r\n![3](https://user-images.githubusercontent.com/28017534/40586823-bea72912-61c7-11e8-8c55-6d7fa55f355b.jpg)\r\n![4](https://user-images.githubusercontent.com/28017534/40586824-bebfe272-61c7-11e8-8d4e-352dcf7c0bd2.jpg)\r\n![5](https://user-images.githubusercontent.com/28017534/40586825-beec4560-61c7-11e8-809b-833d3577d610.jpg)\r\n\r\n\r\n\r\n\r\n\r\n"}}
