Hi,Ive made a custom board with a STM32H735 micro on it. I have built a board with nothing but a micro and a few of its needed passive components and went to provide it power and test that its working. I supplied power from a benchtop power supply wi...
In the last weeks, I was working on running W25Q256 nor flash chip from vendor Winbond with STM32F746 MCU on a custom board. My guideline in this road is ST's how to run QSPI flash video tutorial (5-part video) and of course some genius guys in the c...
Hello everyone. I have a big problem with my custom STM32H7 board, in particular with HAL_Delay.When I add a line on my main.c file to simply print on SWV, the first time seems to work, but after it does not work anymore. It prints the first time, an...
I am using the above library to display simple text msg on the OLED display. It works. However the controller slows down - while(1) loop works as if delay(5000) is implemented. At first the internal HSI clock running at 8Mhz was being used. Thinking ...
I am using a STM32U545 Nucleo board with a purpose of measuring up to 8 Square wave frequencies simultaneously averaging between 100KHz to 1.5MHz. I only need to measure frequency with as much as accuracy achievable. Finally, I plan to transfer all t...
Hi people,Im working on STM32H723 module and using SPI6 with LL and/or registers. Even when using HAL libraries I have same issue. SPI stops working randomlyI need to send several messages every (e.g.) 25 ms, (I tried 50 ms). Main Clock is set to max...
I'm trying to experiment with a Custom HID USB demo.I'm following the instructions at:How to implement a USB device custom HID class on ... - STMicroelectronics CommunityPart way down it suggests:However when I got to Middleware I don't have USB_DEVI...
Hi everyone,I'm working with the NUCLEO-U575ZI-Q board and using the ADC_SingleConversion_TriggerSW_Init example. However, I can't get the ADC to measure correctly. No matter what voltage I apply to pin 9 of CN7, the reading always stays around 80mV....
According to the description of Section 7.3.2 "Error code correction (ECC)" in the RM0456 manual, reading the data at address 0x0BFA1F80 is supposed to generate an NMI interrupt.However, when I tried to read the data at this address, no NMI interrupt...
I need to measure 0 to 80V DC voltage with STM32F373CCT6 and I have some questions to get the best performance of the SDADC.*Is this CPU and 16-bit SDADC good for this purpose?*Is it better to use the internal 1V8 Vref or an external 1V8 or 3V3 Vref?...
