Hi, I am using STM32L4R9ZIJ6 with power pin connections as following image.On the same design where VREF+ pin is connected to P3V3, if I configure Vrefbuffer for ADC measurements & use Vrefbuf as 2.5V, I observe that current draw from P3V3 goes from ...
Spent two days of trying to see printf via USART1 from U585 and U575 boards. Was trying to load BLE via DFU on B-U585 and get it work but USART1 became silent. (Wrote separate post on B-U585I-IOT2A as documentation nightmare). Problem: USB-C + STLIN...
Hello, I'm working on finding the smallest possible power solution for the STM32N6. The reference boards(STM32N6570-DK and STM32N6 Nucleo-144) uses multiple discrete buck converters and LDO to power the N6. It must be possible to do it smaller. From ...
I’m performing low-power consumption tests using the NUCLEO-U545RE-Q development board. However, after entering STOP2 mode, I observed that the current consumption remains around 23 µA, which is significantly higher than the typical values stated in ...
In the Datasheet, Table 16 specifies TJMAX as 150 °C, but Table 17 indicates the TJ range as -40~130 °C, which one should I refer to?Table 16. Thermal characteristicsSymbol Ratings Value UnitTSTG Storage temperature range –65 to +150 °CTJ Maximum ju...
Hello, I've just received my custom PCB with an STM32H743VIT6 MCU. It has a Samsung eMMC connected to the SDMMC1 interface (MMC 8 Bits Wide Bus) : (I'll link the eMMC datasheet below.) I'm encountering some issues while initializing the device with ...
I'm attempting to use a stm32g030 as an I2C slave device however the mcu fails to accept connections with the master device. I have run this code on several different board including several using a stm32g031 but experience the same issue so I am t...
Which pin is the VSSA of STM32L051K8U6?
As title really. Keyboard project i'm working on in QMK required a bit more RAM so upgraded from the STMf401 to an STM32F412xE. Flashed firmware onto it RGB animations and OLED work correctly but USB device not recognised by computer. STM32cubeprogra...
