Hi,I want to debug the H753ZI through USART2 and connect to the PC through USB. I've done this a lot with other NUCLEO boards. Apparently this feature is not present on the H753ZI board?Is there another UART connected to the ST-link on this board? Or...
Hi.After firmware upgrade for st-link v2, windows computer recognized the st-link as universal serial bus instead of virtual com port. whenever i try to program to MCU, there is error like a "No target device found".How can I solve it?Below image is ...
Hii hope im asking my issue in the right placeso i have developed a pcb board with 70 TLC5947 ic's in cascading sequence, however im having an issue with using my STM32 discovery board to turn on LED's. the Ic's are powered by 5V and when i use my ar...
I am trying to use the external i2c connector (CN4) on the STM32H753I-Eval2 board to connect with the i2c connector (CN2) on STM32F769I discovery board. STM32H753I works as master and STM32F769I works as slave.On STM32H753I, the function "HAL_I2C_Mas...
I want to program my STM32F091CC with the ST Link/V2 through Arduino. I downloaded the stw-link009 software and I can push Arduino code to the STM32. The problem is that I can not get serial communication so I can see serial prints or debug my code. ...
I want to design a board that has an STM32H7 with internal SMPS and an SSD2828 which needs 1.2 V too.I'm wondering if it is possible to use the internal SMPS of the microcontroller to produce the 1.2 V for Vcore like the below picture and also use th...
Does the STM32L072VBT6 or STM32F072VBT6 not allow for the USB connection to function, even when VDD is OFF?
Here are the stm32f401re schematics and pinouts. I want to see the timer in channel 1 and use that timer to cooperate in the PWM channel. There are no timers other than channels 1 to 4. However, I only see pwm channel on channels from 5 to 9. How can...
Hi, I need to add an ethernet interface to a STM32H745IIT6 MCU. I have to choose the RJ45 connector and the Ethernet Transceiver chip.I state that I've never done this thing, so my idea was to take the Nucleo board schematic and use the same connecto...
