HeyI am working with NUCLEO-H723ZG. I try to sample signal of sine wave at 25KHz to buffefr with size of 100.I want to get something Like Interrupt when the buffer is full.I look for some examples in the internet about the configuration of the IOC bu...
Hi all,Just read RM0440, the section is USART Baudrate generator. There is the formula contatins input never met in all other document. (found 3 times, all of them are on the screenshot). What happened with ST technical writers? I never met cases lik...
We are using a Any bus module M40 in our project which is based on STM32F769BI.The FMC interface is connected to the Any-bus module as per the attached schematics. This interface works for 8-bit mode of anybus. However for 16-bit mode it is not worki...
Hi,I would like to use this device: STM32H753VIT6 to communicate withan SD-card in SDR104 mode.As I understand it would require an I/O voltage on the card side of 1.8V. This is where I become insecure if the given device can generate this voltage int...
Hi,We develop a device based on STM32H7B0. We use this microcontroller with QSPI external flash. In the internal flash we keep our bootloader and in the external flash resides application code. We are now testing our devices and we had 3 cases when t...
On Thursday, June 29, 2023, I attended the "STM32H5: Ultimate combination of performance, integration and affordability" workshop, which I find very interesting. Workshop participants were informed that the slides and a voucher to order the STM32H5 d...
I spent hours trying to figure out why my interrupt didnt work. I have to say that i didnt go with the HAL_FDCAN_ActivateNotification, so its a bit of my own fault.Nevertheless would i would like to now, if this bit is of a use and if there is more t...
Hello,In my application i need to run double for loop for data inside SRAM. and I would love to speed up my program as much as possible.uint32_t xs = 0, yx = 0, sum =0, i = 0;for(uint32_t x = 0 ; x<600 ; x++){ for(uint32_t y = 0 ; y<600 ; y++) ...
Dear experts, A question in relation to OB behavior discussed this thread: https://community.st.com/t5/stm32-mcus-embedded-software/stm32-is-getting-stuck-frozen-and-enables-read-out-protection-at/td-p/615228Is there documentation or App note that ex...
Hi , Is there an automatic calibration routine for the STM32L471RGT6 ADC? If there isn't can someone point me to example code on how to read the internal reference (or some other approach) so I can write code to perform calibration. Thank you very mu...
