LTDC layer testing on hardware The term "LTDC layer" typically refers to the Layered Timing Controller (LTDC) in embedded systems, particularly in microcontrollers and display driver circuits. LTDC…
LTDC Layers initialization coding Configure pitch, line length, and total lines of the frame buffer . These parameters define how the display data is organized and how the…
LTDC Layers initialization coding and windowing explanation In the previous article, we explored a few registers of the LTDC layers. In this article, let's continue with our coding…
LTDC layers initialization The LTDC (Layered Transmission Display Controller) is a hardware component commonly found in embedded systems and graphics display controllers. It allows for the simultaneous display…
LTDC signals trace analysis The LTDC signal traces are the electrical connections that transmit data from the graphics controller to the display panel. The signals may include pixel…
LTDC background testing Configuration horizontal synchronization and vertical synchronization timings code. void LTDC_Init(void) { LTDC_TypeDef *pLTDC = LTDC; REG_SET_BIT(RCC->APB2ENR,RCC_APB2ENR_LTDCEN_Pos); //Configure horizontal synchronization timings REG_SET_VAL(pLTDC->SSCR,(BSP_LCD_HSW-1),0xFFFU,LTDC_SSCR_HSW_Pos); REG_SET_VAL(pLTDC->BPCR,(BSP_LCD_HSW+BSP_LCD_HBP-1),0xFFFU,LTDC_BPCR_AHBP_Pos); REG_SET_VAL(pLTDC->AWCR,(BSP_LCD_HSW+BSP_LCD_HBP+BSP_LCD_ACTIVE_WIDTH_LANDSCAPE -1),0xFFFU,LTDC_AWCR_AAW_Pos); uint32_t…
