STM32 MCUs TouchGFX and GUI

OV2640 on STM32F446ZE using DCMI DMA and UART with NUCLEO board

Hello,I’ve been working for a few weeks on a personal project concerning cameras with OV2640 sensors. I am using a MCU F446ZE mounted on NUCLEO board. As you can see from the product tab, to use this card for cameras, implies the use of various links...

STM32 Blue pill doesn't execute code on power up, execution starts after i press reset

Hello, I'm using stm32 blue pill and my code communicates with several sensor using UART and displays it on LCD using i2c. My code works perfectly fine on debug. But when i power it again, it doesn't start execution. Although power LED is ON but code...

Resolved! HAL_UART_Transmit_DMA with unwanted behaviour

I am working with the STM32H745XIH6 disco board to use HAL_UART_Transmit_DMA and send 3 different strings. But what I receive on the terminal are corrupted data. At least on the 1st send of every string, the string are not shown correctly.Let's say t...

How to add TouchGfx to project built from UART Example?

I have built up a CubeMX project from an example, is it possible to add TouchGfx to the project now? If so, how? It seems to be taking me in circles.Thanks

Resolved! Making changes in CubeMX does not import necessary files in Drivers folder

I created a project in TouchGFX Designer and then I opened the project in CubeMX. It compiles successfully. But then I want to add UART function to my project. So I go to CubeMX and add UART function but when compiling it gives an error because the s...

C++ STM32H7 + TouchGFX + ThreadX + ESP32 MQTT - heap allocation

Hi, I'm working under not very restricted medical device with WiFi logging. This is quite a big project, requires processing of many string data so I want some easier tools. I know that in general it is not good to use heap on embedded, but H7 seems ...

Resolved! Adding UART to STM32H7 based TouchGFX project creates multiple build errors.

I've created a TouchGFX (TouchGFX Designer v 4.21.1) project using the STM32H7B3I-DK board. The project has a couple of gauges where I'm able to manipulate their setting based on a load cell being read through an ADC. Everything is working fine. N...

I am using an STM32F469I$AU1 development board. I am also using the TouchGFX Ver 4.21.0 to develop a UI. I want to communicate through the virtual COM port using printf so I have modified the main() function in stm32cubeide to redirect printf().

I have redirected printf to output through USART3. USART3 is being properly initialized. I have checked that it is sending data through USART3 up to function HAL_UART_Transmit(&huart3, &*c, 1, 10); and everything looks right but no data goes out the...

USART1 and dynamic graph

Hi, I want to receive 20 bytes.I want to receive them every 2 milliseconds and simultaneously.To show data, I am working with TOUCHGFX. I use dynamic graphs to show them.The problem is, I want to show 12 bits on each graph.I debugged my code , it sea...

UART sending data problem using TOUCHGFX

Hi, Im working on touchgfx with STM32H750XBH-DK eval board and gyro sensor. So I try to display the data using UART which I want to display using serial monitor(tera term) but its doesn't work and nothing display in my monitor.Basically i have try us...
