Hi, I'm having trouble getting my application to run at a different firmware address. The end goal is to be able to have the application running, receive new firmware over the UART. The new firmware will be saved higher in Flash (0x08100000, LENGTH...

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...

Update #1. Looking at Cube programmer the memory location (0x08008000+4) shows 0x080081BD. Which matches the value for "app_reset_handler" when debugging.I'm not understanding the value in the .map file showing the reset handler at 0x080081bc? Upda...

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...

Firmware Update on STM32L4S9ZITx with bootloader and dual bank firmware

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?
