在15M上面,遇到这么一个屏,问一下LCM_get_params应该怎么配置才对
params->dbi.port = 0;
params->dbi.clock_freq = LCM_DBI_CLOCK_FREQ_104M;
params->dbi.data_width = LCM_DBI_DATA_WIDTH_18BITS;
params->dbi.data_format.color_order = LCM_COLOR_ORDER_RGB;
params->dbi.data_format.trans_seq = LCM_DBI_TRANS_SEQ_MSB_FIRST;
params->dbi.data_format.padding = LCM_DBI_PADDING_ON_LSB;//?
params->dbi.data_format.format = LCM_DBI_FORMAT_RGB666;
params->dbi.data_format.width = LCM_DBI_DATA_WIDTH_18BITS;
params->dbi.cpu_write_bits = LCM_DBI_CPU_WRITE_8_BITS;
params->dbi.io_driving_current = LCM_DRIVING_CURRENT_6575_16MA;
params->dbi.port = 0;
params->dbi.clock_freq = LCM_DBI_CLOCK_FREQ_104M;
params->dbi.data_width = LCM_DBI_DATA_WIDTH_18BITS;
params->dbi.data_format.color_order = LCM_COLOR_ORDER_RGB;
params->dbi.data_format.trans_seq = LCM_DBI_TRANS_SEQ_MSB_FIRST;
params->dbi.data_format.padding = LCM_DBI_PADDING_ON_LSB;//?
params->dbi.data_format.format = LCM_DBI_FORMAT_RGB666;
params->dbi.data_format.width = LCM_DBI_DATA_WIDTH_18BITS;
params->dbi.cpu_write_bits = LCM_DBI_CPU_WRITE_8_BITS;
params->dbi.io_driving_current = LCM_DRIVING_CURRENT_6575_16MA;
没有明白是什么意思。
就是初始化的时候 8BIT Command和Parameter通过9BIT数据线的高8位即 D1~D8 写入数据,现在是白屏,背光已经亮了。
第一次接触智能机驱动,不是什么大问题,已经搞定。
请回复一下,具体是怎么搞定的?
数据移位而已。
