Hello,I tried to import my time interrupt based, blinking LED project into Visual Studio 2022 V17.6 (Not into VSCode) using Marc Goodner’s blog (from Microsoft). Finally, I could import the STM32CubeIDE project into VS2022 but I could not run it. The...

After assembling the X3 external 25MHz crystal and 2 caps and generating initialize code for 550MHz clock with CubeMX my NUCLEO-H723ZG board runs fine, except ADC. It is very noisy. The CubeMX configured the clock for ADC = 96.000671 MHz (PLL2P). In ...

I have NUCLEO-144 H723ZG board. I created a frequency meter app for the NUCLEO board, but the quality of the frequency measurement a sinusoidal voltage is very poor. I have a generated 720mV RMS, 126.7Hz signal between 0 and +2.5V (max) biased to +1....

A 720mV RMS sine wave, biased to +1.25V is connected to the PB2 pin. PB2 is the COMP1 positive input. The COMP1 negative input is connected to the internal reference voltage (+1.22V) The output of the comparator is connected to PA0 which is the input...

NUCLEO-H723ZG dev. kit.I need take over the full control of the USARTx. I need a TX interrupt and the RX interrupt handled manually independently the HAL_UART_*** functions. The HAL_UART_Receive_IT() and the HAL_UART_Transmit_IT() is useless for me. ...

I think I found the solution.Import the STM32CubeIDE project to Visual Studio.After importing the project the Debug button (Green "run button") shows "Select Startup Item..."Click on the down icon on the right side of the Debug button.Select "Launch"...

Thanks Pavel for the link. I will check it.Louis

Yes, I would do this if I had my own custom board. We have no time for such a deep level debugging even for not our product. My job is to decide whether we can base our new transmitter on STM32H723ZG CPU or not. So the best would be to get an WORKING...

Hi LCE,The board is the STM32H732 NUCLEO-144 development kit made by STM. I can't add filtering RC to the inputs.The PCB wiring is made by STM.Yes, in the ADC Conversion Ready callback function the application converts the 16-bit conversion results t...

I would appreciate very much if somebody would answer these question or explain why the conversion results of the ADC converters is so awful.Louis

H723ZG Nucleo ADC clock/noise question

Frequency measurement with COMP1 and TIM2 NUCLEO-144 H723ZG board

Why does NUCLEO-144 H723ZG measure period time with almost 1Hz error?

How can I use UART manually, without HAL_UART_***() functions?
