But it could not work at WIDTH=256, So I check source codes under folder clib. Then I find uncomment \"#define U8G_16BIT 1\" to use larger piexls. But, it still not work!\r\n\r\nSo I changed all \"uint8_t cnt\" to \"u8g_uint_t cnt\" under clib folder. For example, \"u8g_WriteSequence(u8g_t *u8g, u8g_dev_t *dev, uint8_t cnt, uint8_t *seq)\" change to \r\n\"u8g_WriteSequence(u8g_t *u8g, u8g_dev_t *dev, u8g_uint_t cnt, uint8_t *seq)\"  \r\nAnd changed all \"uint8_t arg_val\" to \"u8g_uint_t arg_val\". There are many file changed.\r\n\r\nAfter change of above, the u8g lib could work at 256x128 LCD.\r\n\r\nI'm not sure this is a bug or I'm not use it correctly, email me QiaoJiannan@vip.qq.com if need any detail."},"comment":{"url":"https://api.github.com/repos/olikraus/u8g2/issues/comments/231525756","html_url":"https://github.com/olikraus/u8g2/issues/29#issuecomment-231525756","issue_url":"https://api.github.com/repos/olikraus/u8g2/issues/29","id":231525756,"user":{"login":"QiaoJiannan","id":14050531,"avatar_url":"https://avatars.githubusercontent.com/u/14050531?v=3","gravatar_id":"","url":"https://api.github.com/users/QiaoJiannan","html_url":"https://github.com/QiaoJiannan","followers_url":"https://api.github.com/users/QiaoJiannan/followers","following_url":"https://api.github.com/users/QiaoJiannan/following{/other_user}","gists_url":"https://api.github.com/users/QiaoJiannan/gists{/gist_id}","starred_url":"https://api.github.com/users/QiaoJiannan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/QiaoJiannan/subscriptions","organizations_url":"https://api.github.com/users/QiaoJiannan/orgs","repos_url":"https://api.github.com/users/QiaoJiannan/repos","events_url":"https://api.github.com/users/QiaoJiannan/events{/privacy}","received_events_url":"https://api.github.com/users/QiaoJiannan/received_events","type":"User","site_admin":false},"created_at":"2016-07-09T09:37:39Z","updated_at":"2016-07-09T09:37:39Z","body":"Yes, close is ok.
