HI We are thinking about a method for detecting people. The prerequisite is that we need to detect people by penetrating a plastic case with a thickness of about 3mm (white). The existing PIR cannot penetrate the case, and radar sensors are expensi...

hello,For me stm32f746-disco has two versions.1) The first is the green PCB. The following label is attached. MBI1191 B-03 / 2154300550 -> LCD screen normal operation / LCD Touc normal recognition2) The second one is the blue PCB. The fol...

helloI have some additional questions. Does the white plastic necessarily contain TiO₂?Are dark colored plastics generally free of any harmful ingredients? Once I have reviewed the plastic components, I plan to do a detection test with a ToF sensor r...

Thanks for the reply.We are working on creating a project in TouchGFX Designer.Is there a way to solve the LCD Touch problem caused by the above change in TouchGFX Designer?

Hello MBI1191 B-03was determined by looking at the labels on your Discovery Kit.The problem is that MBI1191 B-03 has good LCD touch and MB1191-F746-C01 has no LCD touch.Maybe the touch controller has been changed?Thank you!

Even in the FreeRTOS environment, the HAL_UART_Transmit function is called normally and the value is put in the huart->Instance->TDR part. while (huart->TxXferCount > 0U) { if (UART_WaitOnFlagUntilTimeout(huart, UART_FLAG_TXE, RESET, tickstart, Ti...

Can a TOF sensor detect a person through a plastic case?

Trying to reduce motor noise. (STM32)

In the ToughGFX Designer, select stm32f7508-disco with the same PCB shape to create a project and write to stm32f746-disco, and the touch works well.

Depending on the stm32f746-disco version, the LCD touch operation of the code generated by TouchGFX does not work.

I am doing UART communication with STM32H735G-DK. Without FreeRTOS, It works fine if you do it like this: HAL_UART_Transmit(&huart1, str, sizeof(str), 1000); However, there is no UART output in FreeRTOS.
