Nucleo-L433RC-P board with a BlueNRG-2 BLE
Hi I am testing the Nucleo-L433RC-P board with a BlueNRG-2 BLE interface. I configured the setup, but the BLE device is not being detected in the ST BLE app. Look at pic, Any modifications require are not ?

STM32N6: Debugging Issues with External Flash and RAM Debug in FSB & App
Hello,We are using the STM32N6 series MCU in our project and encountering issues during debugging. I’ve attached a screenshot of the error message we are seeing.We followed the steps outlined in this guide:https://community.st.com/t5/stm32-mcus/how-t...
Resolved! STM32N6: Retain RAM contents across resets for OTA firmware updates
Dear all,I'm implementing Over-the-air firmware updates for a board using the STM32N657 MCU.In the Appli, I download the new firmware binary over Wifi and store it to RAM at a fixed location in AXISRAM5 and 6. In order to flash the new binary to the ...
Unusual signal pattern at the output of STM32G474 DAC3
Hello,I am implementing a sine wave generator based on the high-speed DAC3 of the G474.The DAC is in double-DMA mode and its conversions are triggered periodically by a timer.Sample and Hold is disabled.The DAC is connected to an external pin by an ...
Resolved! UART receive with HAL_UART_Receive_DMA
Hello everyone on the forum.I have created a UART DMA receive program with Nucle-H723.This time it is working properly, but sometimes it does not work properly.DMA set up in normal mode on UART4 RX.DMA initialization function of UART.void UART_DMA_In...
Resolved! On the STM32G441, starting TIM1 CH2 (Set MOE reg) pulls down the PB6 USART1 pin.
Hi.I am currently developing a motor control platform using STM32G441 and am facing a problem.I am controlling a 3-phase motor with TIM1 based on packets from Half duplex USART1 (PB6), but when I Start TIM1 CH2, the USART1_TX pin, which should be unr...
Resolved! Unable to get ADC value on STM32N6570-DK
Hi everyone,I’m currently working with the STM32N6570-DK board and trying to read an analog signal using the ADC1/2 INP8 channel (PB10) using the MB1280C Fanout board (Pin 13) with STMOD+ connector. However, I'm consistently getting a value around ...
Resolved! STM32H7 + Zephyr + SIGTRAP 0xA05F0000
I'm running into an issue on two boards (an STM32H735 Discovery Kit) and a custom board with an H743. #include <stdio.h> #include <zephyr/kernel.h> int main(void) { while (1) { printf("Hello there, world!\n"); k_msleep(1000); } return 0; }If ...
Resolved! [RTC / LSE] Irregular second jumps when using an external 32.768 kHz crystal on STM32L412K8
Hello everyone, I’m using an STM32L412K8 microcontroller with an external 32.768 kHz LSE crystal to operate the RTC for real-time clock functionality. However, I'm facing two issues: Second jumps: the seconds skip multiple values out of order (for ex...
Resolved! Opamp on STM32U545 is impossible to read with ADC_IN8
Hello.I am finishing a project where I measure voltage with an ADC using the STM32L431 and, for greater accuracy, I am using the OPAMP (PA0 = ADC1_IN0_VINP and PA3 = ADC1_IN_VOUT). For the STM32L431 on the STM32CubeMX, when activating the OPAMP in "F...
