TTL Screen

• config PAD to TTL mode：
  #vi infinity2m-ssc011a-s01a-padmux-display.dtsi
  
• Obtain the timing table from the data sheet on the screen:
  
• Modify screen parameters
  You can copy sdk/verify/application/jpeg2disp/src/SAT070CP50_1024x600.h and modify it on the basis:
  
  Pay attention to the values of the following variables:
  m_ucPanelHSyncWidth = HSYNC.(Front Porch) + HSYNC.(Pulse Width)
  m_ucPanelHSyncBackPorch = HSYNC.(Back Porch)
  m_ucPanelVSyncWidth = VSYNC.(Front Porch) + VSYNC.(Pulse Width)
  m_ucPanelVBackPorch = VSYNC.(Back Porch)
  m_wPanelHStart = m_ucPanelHSyncWidth + m_ucPanelHSyncWidth
  m_wPanelVStart = m_ucPanelVSyncWidth + m_ucPanelVBackPorch
  m_wPanelWidth = HSYNC.(Display Period)
  m_wPanelHeight = VSYNC.(Display Period)

m_wPanelMaxHTotal
= m_wPanelHTotal
= m_wPanelMinHTotal
= m_wPanelHStart + m_wPanelWidth

m_wPanelMaxVTotal
= m_wPanelVTotal
= m_wPanelMinVTotal
= m_wPanelVStart + m_wPanelHeight

m_dwPanelMaxDCLK
= m_dwPanelDCLK
= m_dwPanelMinDCLK
= m_wPanelHTotal * m_wPanelVTotal * FPS(自定义)

(DCLK Frequency).min <= m_dwPanelMaxDCLK <= (DCLK Frequency).max

• Modify the value of swap
  
  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. Need to pay attention to the following 4 values:
  m_bPanelSwapOdd_RG, when the value is 0 or 3, it corresponds to R; when the value is 1, it corresponds to B; when the value is 2, it corresponds to G;
  
  m_bPanelSwapEven_RG, when the value is 0 or 2, it corresponds to G; when the value is 1, it corresponds to B; when the value is 3, it corresponds to R;
  
  m_bPanelSwapOdd_GB, when the value is 0 or 1, it corresponds to B; when the value is 1, it corresponds to B; when the value is 2, it corresponds to G;
  
  m_bPanelSwapEven_GB, when its value is 0, the RGB high and low bits are not inverted; when the value is 1, the RGB high and low bits are inverted;
  
  When the high and low bits are not inverted, the pin correspondence is as follows:

After the high and low bits are reversed, the corresponding relationship between the pins becomes:
