STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
I am not an ST expert nor RTC expert, whatever that means. but I have seen several implementations made by other companies and I have to say RTC as counter (the HW that provide interface to a posix compatible timestamp, usually 32 bit seconds + 15 fr...
I am trying to communicate with an SD card using SPI.I have found a library, that can work on an STM32g031f6, but if I try to do the same on an STM32g030j6, it crashes/resets when it calls the function "__HAL_SPI_ENABLE" in "stm32g0xx_hal_spi.c".I ha...
I am receiving data from UART in uint8_t array.I want to convert array to string to work on it:if (Received Data=="Reset") { resetFunc(); }if (Received Data.substring(0,8)=="ABCDASD"){ Do something }if (Received Data.substring(4,8)=="ABC1234"){ int...
I'm currently working on custom board that uses a stm32f2xx chip and PHY chip that is different than the one in dev/nucleo boards. I noticed that I need to change HAL code to get this combination working as the MAC and PHY initialization is combined ...
Hello, I have a custom STM32F439VITx based board, with two analog sources wired to PC0 (ADC1_IN10) and PC1 (ADC1_IN11). The sources need to be read infrequently, on the order of every five to ten seconds, and independently of each other (so sometimes...

I'm trying to use HAL_ADC_GetValue to get the ADC value from an STM32L082 attached to a battery giving 3.7V. My goal is to use the ADC value to estimate the battery percentage so I need the ADC value when the battery is full and when it's mostly empt...
Could you tell me what I'm doing wrong?I want to draw a sinusoidal chart. But for some reason, it is not displayed in the window of "SWV Data Trace Timeline Graph".PS - A "cleanSignal" it is a global variable.
i use stm32f410rb microcontroller. one board contain four stm32f410rb micro controller,my requirement is load firmware all four microcontroller using single connection(uart bootload or jtag or swd or any other programming method ,) so please suggest ...
