I'm just getting through some initial debugging on my board using an STM32H7, connected to the : NHD-5. We made the general settings in the previous paragraph, these include setting the timings of the background layer. Some stemwin examples that build will not flash, for example STemWin_acceleration_CM7. This example will convert several channels. STM32H747-DISCO 2. The other solution would be to use a slower pixel clock, but this induce flickering on the LCD. Nov 7, 2024 · As a first check, we noticed that there are differences between the pinout for the display connector of the LTDC_ColorKeying example and the pinout of the schematic:. The ST document titled ’Out-of-the-box GUI Software (BSPs) available for STM32 display kits’ (link below) indicates that ‘out-of-the-box’ support for LVGL is available specifically for three development boards, namely NUCLEO-G071RB, STM32H7B3I-DK I'm just getting through some initial debugging on my board using an STM32H7, connected to the : NHD-5.
