I am currently looking for a microcontroller or processor with MIPI DSI output. The STM32 devices have this, but there is something that does not seem to make sense. They only have 512kB of internal memory. This would not be enough to hold a single f...
Hello, I have a project with STM32L4R9AI and touchgfx. I use DSI for amoled display. I am developing codes for months. At some point screen is started to be locked ( no changes in screen ). While debugging the code when I look at the freeRtos task ta...
I am working on a test on the stm32f469i_Discovery board.On the stm32f469i, the MIPI interface operates with the OT8009A LCD. Instead of OT8009A LCDs, it is planning to connect the stm32f469 with other LCDs.The LCD control IC uses the ILI9806E while ...
Hello There,I'm new to DSI based Displays. We have got a DSI Display of 720(H) x 1280 (V) resolution which is based on ILI9881D and supports 2 Lanes.I want to know whether STM32F469VET6 could support it? As I couldn't find any guide for this.Any help...
I am trying to operate 480x272 RGB LCD, SDRAM(for graphic memory), flash memory(for log), BLDC motor, wifi, sound, freeRTOS. At first, it was implemented with STM32F767IIT (flash-2MB, ram-512KB). Since there are too many pins connected to SDRAM and L...
Hi,I am trying to use touch gfx library on a stm32l4r9aii mcu and i use 454*454 pixel amoled lcd, i can not write anything to lcd, So i have noticed from webinar notes that L4R9 mcu can drive up to 450*450 mpi dsi displays. Is my problem about my mcu...
Since I don't have a round display, I don't need this lookup table to convert the bit locations, but there is no obvious way to not use it. How do you bypass this GFXMMU look-up table method and just send the raw image array to the DSI path? I am usi...
Hi,I am trying to drive 454*454 px amoled lcd with stm32l4r9 mcu and the image cannot be displayed properly. I am using the cubemx settings and the desired settings according to lcd datasheet. Any advise ?
Hello,I hope someone can help me. After days over days reading docs, other questions and so on i am still confused how all the LTDC and DSI stuff works.OK, so what i have is a STM32F469 Disovery board which already has a display on it.I create a proj...
Hello everyone,Objective : Send pixel data to LCD module using DSI-HOST on APB command mode.What I can do :+ Read the LCD module's GRAM content ..+ Send basic commands like Turn ON / OFF the Display, Pixels, Sleep IN / OUT ..+ Send long write command...
