Good day to everyone on this forumI was working on a code, my borad is a Nucleo-144 STM32F746, At first I was trying to read 12 Analog signals, from 0 to 3V with DMA and the reads were good exept for some channels with noise and a weird offset, I red...
Hi,we have a strange behaviour which could be resolved by changing clock configuration, but we cannot explain why the errors occured in the first place. Perhaps some of you have any idea why the following happened:random hardfault during runtime afte...
In RM0091 rev.9, footnote 2 to Figure 273 on Page 760 has the following text:All the events associated with the transmitter receive flow must be ignored in standard transmit only mode (e.g. OVF flag).There is no OVF flag in the 'F0xx SPI; this shoul...
Hello,I have developed a device using an STM32F4 but am now trying to either add BLE or merge to an SoC with BLE and don't know the easiest path forward. I need OOB pairing using NFC but am very limited in PCB space.Does ST provide an all in one SoC...
Hello,Does anybody know if there is any prerequisite when enabling or disabling the prefetch buffer?More specifically, in the Nucleo L4R5ZI sleep example the prefetch buffer is disabled in main() just before the main loop. It is never re-enabled afte...
Hello, I'm trying to debug my NUCLEO STM32H7A3 in STOP mode and run into this problem:When I set a breakpoint after the STOP mode, the breakpoint is hit correctly and everything works as expected, even step in or step out, but when I click on RESUME ...
I'm using the 4K of battery backed RAM on the STM32H743 to preserve variables between power cycles. This works fine on 90% of identical systems running identical firmware and with identical H/W, identical chip versions etc. i.e. data is exactly what ...
I can configure MDMA for SDMMC1 in STM32H730 in STM32CubeIDE.But I do not understand how to enable it for SDMMC2. In the documentation it says SDMMC2 has a direct access to DMA1 & DMA2. But I could not see it in DMA configuration panel.Could you help...
According to 93LC66 communication the 93LC66B variant is a rotated variant. How to establish communication between NUCLEO-G474RE and this EEPROM using SPI ? I've tried many approaches but none worked, always get 0 from EEPROM but it should be FF, I t...
