Modify screen parameters
Link from Baidu cloud —– Download JpegPlayer.rar And unzip, find SAT070CP50_1024x600.h, and modify the corresponding data according to the actual parameters of the screen
For the screen parameters of the 7-inch development board with its own screen, please refer to the screen parameters file in the network disk: development board —-> lcd folder for verification

By default, the corresponding relationship between each TTL pin and RGB is as follows:
If the actual connection is not the default connection, you need to modify the swap value. We need to pay attention to the following four values:
M_bPanelSwapOdd_RG, if value is 0 or 3, corresponds to R; if value is 1, corresponding to B; if value is 2, it corresponds to G;
m_bPanelSwapEven_RG, if value is 0 or 2, corresponds to R; if value is 1, corresponding to B; if value is 3, it corresponds to G;
m_bPanelSwapOdd_GB，if value is 0 or 1, corresponds to B; if value is 3, corresponding to R; if value is 2, it corresponds to G;
m_bPanelSwapEven_GB, if value is 0, the RGB high and low bits are not reversed; if value is 1, the RGB high and low bits are reversed;
In the case that the high and low positions are not reversed, the corresponding relationship of pins is as follows:
After the high and low bit are reversed, the pin correspondence becomes:
