Hi, I am looking for an accelerometer. I wonder if there is any ST MEMS chip that meets my requirements:I don't need very high max G force: 4/8G should be enoughLow power consumptionAble to send trigger, like a GPIO rising or falling signal, when acc...

Hi,I have a PCB with F411 as MCU.MCU VBAT pin is directly connected to battery positive pin.I try to use ADC1 to read the VBAT value. Here is the ADC1 init code: ADC_ChannelConfTypeDef sConfig = {0}; /* USER CODE BEGIN ADC1_Init 1 */ /* USER ...

In my app, I need MCU to go to stop mode and then wake up by RTC timer. I follow this RTC wake up example and manage to make MCU go to stop mode for a few seconds and then wake up. Because in my app, we want MCU to wake up once in a few hours instead...

I am using F411 as the main controller of some DAC/ADC modules.I need to put MCU in stop mode to reduce its power consumption.I wonder whether or not I need to configure all the I2C, SPI, and UART interfaces when MCU wakes up from stop mode.

In my project, my MCU (F411) uses I2C HAL API routinely to read from a sensor device.When some event happens, my interrupt handler will use I2C API to read from different register from that device; so my question is:Is HAL API thread safe? Although I...

I want to try your Edge AI D Cloud.Any MCU to recommend? I prefer low-powered consumption, because my app may use battery.

I wonder what the differences are between STM32-provided library and those in Github.

I tried the DWT method in my code. It basically works.However, I have 2 issues:The delay time is not so accurate; and does not go linear with input value.I wonder if it's OK to call DWT_Delay_Init(void) multiple times.

yes, you're right. @AScha.3 Once sampling time is changed to maximum: for F411, it's 480 cycles.The reading becomes accurately close to measured value.

Forgot the add the DMA for ADC1 code: /* DMA controller clock enable */ __HAL_RCC_DMA2_CLK_ENABLE(); /* DMA interrupt init */ /* DMA2_Stream0_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA2_Stream0_IRQn, 0, 0); HAL_NVIC_EnableIR...
