I'm building a simple application that collects environmental data from sensors (pressure, temperature and humidity) using the B-U585I-IOT02A development board. Since I want to deploy the node directly on the field, I'm planning to power the board us...
Hi, I'm using a Nucleo-H723 board and I need to sample 4 ADC's with variable sampling rate, maximum 1Mbps.I configure the TMR2 with the time stamp (10ms, 1ms, 10ms, etc...), and TMR3 with the sampling rate that is the input for the ADC trigger.Values...
I downloaded the boot code generated by following the settings in Figure 3 (the frequency configuration to 600Mhz) into the flash of the 0x08000000 starting address, and then the stlink cannot detect after re-powering (as shown in Figure 1). But my ...
The STLink-V3Mini is connected to the USB port and the light on the board is green.
Hi all,Anyone have example projects for the following for the STM32H7S78-DK board ?:1)"Hello World". Displaying the text "Hello World" on the display.2)Audio. Playing back a simple tone though the audio output.Am new to development so the included di...
Hi all, I'm trying to test STEVAL-IDB008V2 board with wise studio and BLE_SensorDemo project I can compile and flash with RF-Flasher.So for now I'd like to add my own service, the basic example privde 2 services - Acc service- Env serviceI'm trying t...
Hi all,I have the following problem: the backup domain registers are sometimes cleared on power off/on, despite having a 3V coin cell CR1632 connected to the pin VBAT and the GND plane. The RTC registers are then cleared. The error occurs sporadic. T...
Hello everyone, I would like to know if the Nucleo-H7A3ZI-Q supports the MDIO to external Ethernet PHY control via SMI (MDC and MDIO). I have the setup connected, and I have programmed it accordingly but the MDC and MDIO Lines are always LOW, not eve...
HAL_GetTick() returns the value -128 when called in I2C write memory bite Here are the code snipets how to resolve this error
I am trying to use STM32H7R7L8H6H working on design. So in our design we uses multiple interfaces like TFT LCD, Ethernet(RMII), RS485, Wi-Fi-BLE module. So For MCU power supply mode selection between LDO and SMPS. Which one mode ST will recommended t...
