I'm using an STM32L4S9 MCU and I'm having trouble getting all the channels to update after starting HAL_ADC_Start_DMA. I'm doing a regular 12 bit conversion on 5 channels, trigger by software, waiting for conversion completed in the adc call back ...

320x240 Parallel RGB (LTDC) interface. I've been following the TouchGFX board bring up instructions. I can change the background color, so the hardware side should be good.I made a display in TouchGFX, everything compiles. TouchGFX updated the files ...

I'm setting up a custom board. I was planning to use a NewHaven resistive touch screen with RGB888 and the STM32L4S9. I've been using the stm32F429Disc1 board to learn how to use TouchGFX with Cube IDE. I thought I'd be able to figure out how that wo...

I'm using a STM32F429I-DISC1 board. I can create a display in TouchGFX and it creates the project in the default location "C:\TouchGFXProjects\Display". It makes an IOC file in the "Display" folder "STM32F429I_DISCO_REV_E01.IOC" It makes a "STM32C...

*Edited, I had a long question about why the code wasn't working. I was using an example based on Embetronicx. Here is the git location for his example. https://github.com/Embetronicx/Tutorials/tree/ETX_Bootloader_3.0/Microcontrollers/STM32/STM32F7...

I figured this out, the channels I thought were not updating were updating. I was using a voltage divider feeding into some of the ADC channels for testing, expecting to see about 2000 on the ADC channel. I discovered that the adc was going full sc...

Follow up on the 4.21.1 version: I increased the RTOS Heap to 40k and the task stack size to 5000, then the display worked. I tried to figure which change made the display work, and set the heap back to 30k and task stack size to 4096 and the dis...

I'll triple check 4.21.1. What I did is after we got 4.17 to work, I started again from scratch with 4.17 to make sure I was getting everything setup correctly, then started from scratch for 4.20 and both worked. I then started from scratch again o...

With much help from "MM..1" he figured out that touch GFX version 4.21.1 generated bad code for the the STM32L49. When we used version 4.17 the display worked. I also tested on version 4.20 and the code generated works. I also had " HAL_LTDC_SetA...

Thanks for the response. NVIC is enabled like the screen shot below. The interupt was getting called before I enabled FreeRTOS.I checked vsync and hsync with scope the signals look good.For the init, I don't see much in the PDF to init. This articl...

ADC DMA not updating all channels

I'm trying to get a TFT display to work using Touch GFX on a custom board. Why doesn't the display I make in touch GFX show up?

Resistive Touchscreen, how does TouchGFX know about the Y1,X1,Y2,X2 connections from the screen? And how does it know a button was clicked?

TouchGFX 4.20.0 working with CubeIDE 1.10.1, how do I open and work with the TouchGFX project in CubeIDE?

OTA firmware update for a Nucleo F746.
