I don’t understand why you are using uartData_q->Data without initialization of pointer uartData_q (null pointer) 5:49

Would you make one video about the OTA, Over The Air programming for STM32 wireless MCU?

Hello , great work one question , i have a project with multiple screens and each screen receives specific data over UART , i tried to implement the same structure of this project on mine and i have issues with the model.cpp ,,, any idea or help on this

@cherniyosri8669 Год назад

hello and thanks for the video I'm currently working on multiple screen project... actually 17 screen, each screen receives specific data from uart and displays it , I'm having an issue with modelListener,, when i use the instance to call a specific function in the model::tick, it tells me that the function is undefined in the other screens!! which is what i want! please I've been stuck here for almost two weeks and this is my final year project, i would be grateful for any help ',!

@LunaNLR Год назад

In the ModelListener.h, declare the function as "virtual void uart_Data (char *data) {}" (notice the change of ; to {}). This way the default implementation will be empty and not undefined.

@cherniyosri8669 Год назад

@@LunaNLR thanks for the reply! i tried that as first solution but then data won't display on any screen, but as an update i tried something esle and it eventually worked, i define the function as void in the screenpresenter.h of the screen that i won't need the data to be displayed in! yet i don't know if it makes sense or not!

I tried this with the Riverdi display, but I always get into HardFault Handler after leaving the line modelListener->uart_Data (RData); There's an ErrorMessage: No source available for "touchgfx::HAL::tick() at 0x8021dce"... Found no way to fix this, maybe someone has got an idea?

@ControllersTech Год назад

seems like a lot of people are getting issues with the Riverdi. I will make 2 3 more videos with the display, so that you guys can get an idea of how to make it work.

@SimonKas112 Год назад

Thank you very much!!!

@user-ci4fz9co3b Месяц назад

I also had the same problem. There is some kind of problem with pointers to the uartData_t structure. Instead of pointers, I used the structure itself as an object, and everything became OK! I'm sorry for the poor translation, I don't speak English.

Hi, I am using STM32H735-DK Kit. I configured the touchGFX settings and I generated the code. But when I was open the STM32CubeIde, I didn't see the auto UART configuration. So I wonder why I didn't see the auto UART config. Do you have any solution for this?

@ControllersTech 8 месяцев назад

What is auto uart config ?

@bedirhankoksoy993 8 месяцев назад

@@ControllersTech I mean, in the 02:37 minutes of the video you said UART already selected. But when I tried with the STM32H735-DK Kit it's not selected.

@ControllersTech 8 месяцев назад

What's the big issue ? You can select it manually. Different boards may enable / disable additional things, it depends on the script ST wrote for the partiular board.

I have this error in IAR! Error[Li005]: no definition for "Virtual function table for ModelListener" [referenced from ...\Obj\TouchGFX\gui\screen1_screen\Screen1Presenter.o]

@ControllersTech Год назад

Remove the word virtual from the function you defined in thr modellistener. And define it as an empty function. Void function (arg) {}

hello sir I have same board i want to send data through GUI to modbus RTU(rs485) and received on GUI my modbus communication with slave is successfull but i want to print the received data on display and i am trying to add bodbus_CRC file in the project but there is no core with Inc and Src file to add it help me on this

@ControllersTech 7 месяцев назад

Its in the main project folder, not inside the cubeide folders.

@amorftor Год назад

strncpy(RData, uartData_r->Data, uartData_r->size); modelListener->uart_Data(RData); is says cannot convert 'int*' to 'const char*' but my all codes same as you what can i do

@ControllersTech Год назад

Check your uartData_r structure. I guess you have defined “Data” as an integer array instead of character array

@rafaldrzewiecki3056 3 месяца назад

Riverdi with Stm32Cube is isnt compatibile, when use cube later TouchGfx not working. This display is expensive and support is like children. Not helped

@ControllersTech 3 месяца назад

Riverdi STM32U5 is fully compatible with regeneration from STM32cube. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-lhjI2T527Eo.htmlsi=MR7T5Brh0R1PaFvq
