It works fine and I am upgrading an Arduino sketch -perfectly working with 16x2 LCD (HD44180 based) module- toward Graphic Display, with this powerful Library u8g2. I am using graphic display module Winstar WG12864B with built in NT7107/NT7108 controllers, if I am not wrong one of the KS0108 clones, like Hitachi HD6120x. So I have used ports PA and PB (avoiding PA9 and PA10 used for serial link connections with ST-LINK V2, I am not using USB bootloader) for electrical connections.\r\n\r\nI have set up \"software pinout nomenclature\" reflecting above electrical connections as follows:\r\n\r\nU8X8_KS0108_128X64 u8x8(PA0, PA1, PA2, PA3, PA4, PA5, PA6, PA7, /*enable=*/ PB3, /*dc=*/ PB4, /*cs0=*/ PB0, /*cs1=*/ PB1, /*cs2=*/ U8X8_PIN_NONE, /* reset=*/  PB6); \t// Set R/W to low!\r\n\r\nand respecting comment i have pulled down R/W line. Wiring is pretty clean and many times double checkced.\r\n\r\nVdd is tied at 5V from the ST-LINK output and backlight pin 19 to 3,3V available from the Black Pill board.\r\n\r\nWell using Hello World example I do not see anything. What is wrong?! May I kindly ask you what should I do for discovering why Murphy was not sleeping on today?! Thanks so much."},"comment":{"url":"https://api.github.com/repos/olikraus/u8g2/issues/comments/385761389","html_url":"https://github.com/olikraus/u8g2/issues/597#issuecomment-385761389","issue_url":"https://api.github.com/repos/olikraus/u8g2/issues/597","id":385761389,"user":{"login":"olikraus","id":1084992,"avatar_url":"https://avatars2.githubusercontent.com/u/1084992?v=4","gravatar_id":"","url":"https://api.github.com/users/olikraus","html_url":"https://github.com/olikraus","followers_url":"https://api.github.com/users/olikraus/followers","following_url":"https://api.github.com/users/olikraus/following{/other_user}","gists_url":"https://api.github.com/users/olikraus/gists{/gist_id}","starred_url":"https://api.github.com/users/olikraus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/olikraus/subscriptions","organizations_url":"https://api.github.com/users/olikraus/orgs","repos_url":"https://api.github.com/users/olikraus/repos","events_url":"https://api.github.com/users/olikraus/events{/privacy}","received_events_url":"https://api.github.com/users/olikraus/received_events","type":"User","site_admin":false},"created_at":"2018-05-01T19:13:25Z","updated_at":"2018-05-01T19:13:25Z","author_association":"OWNER","body":"Your display is a 5V display.
