UART sending data problem using TOUCHGFX

[Angle]

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 using UART using the board only and everything is ok but when I want to use the touchgfx, the UART doesn't work. Anyone know why and how to solve the problem?

UART STM32H750XBH-DK pin - USART3(PB11 & PB10)

Already enable the UART nvic parameter. 

so what is the problem?

How do you implement USART3 transmit code, how many char do you want to transmit and what baudrate ?

Inside the TouchGFX GUI task with Model::tick overload or in a specific new OS task ?

Have you read the recommendations below ?
