Hi all,I'm trying to use the I2C2 bus to read from a BNO055 IMU. I've already configured the I2C1 bus to be used by DCMI as I have a camera attached and can't reuse it since it is configured in Fast Mode Plus and the BNO055 can only handle up to 400k...
Hi,I'm working on a project using an STM32G series MCU alongside a processor. The processor runs an application that handles firmware flashing for the STM32.We’re planning to implement firmware upgrades over I2C or UART. However, due to hardware limi...
Hi allI migrated from a Nucleo F746zg to a F756zg. Code and overlay is the same except that I west build against F756zg. Now SPI 1 is not working properly anymore. On the scope I can see that SPI communication starts (CS goes low, MOSI byte is sent, ...
HiDoes the X-NUCLEO-BNRG2A1 BLE module support interfacing with the STM32F407VET6 board? Please let me know.
Hello,I got a stlm32 disco board. I cannot Flash.So,I used STM32 ST-LINK UTILITY. Any connection fail even under reset. This one show Target Voltage Detection Fail. The board is powered by the USB CN2 Connector. The measurment on the CN4 Connector sh...
Hi, I'm wondering if there are any recommendations/guidelines when trying to measure power consumption on the Nucleo-N657X0-Q when running a neural network model, both with NPU acceleration and without on the CPU for comparison. I have access to both...
I am trying to communicate with a MS5837 pressure sensor by I2C with the I2C1 on my STM32H563RGT6, but the I2C communication doesn't seem to see the MS5837. I am pretty sure the connections are fine, and I have 2 pull-up resistors of 4.7kOhms for eac...
Hi, I have one question about this library STM32CubeExpansion_MEMSMIC1_V5.7.0 and PDM moduleIn the example, I tried to find a conversion rate between audio gain and SPLs or Pa. I only found this snippet of code that refers to the amplification factor...
Hi everyone,I'm trying to measure the current consumption of the MCU/NPU on a NUCLEO-N657X0-Q board. According to the reference manual (https://www.st.com/resource/en/user_manual/um3417-stm32n6-nucleo144-board-mb1940-stmicroelectronics.pdf - see par....
After a debug session my nucleo-wl55jc1 dev kit cannot connect to my pc using cube programmer or cube ide. When i plug it in to my pc i get this error "The interface firmware FAILED to reset/halt the target MCU" in a text file. LED4 is permanently ...
