GPIO Analog Mode vs Alternate Function ADC

Hello,I am trying to do a voltage measurement, i know i can use ADC to do it. What a gpio is capable of when it is configured as Analog Mode? Can it measure voltages? or Can it trigger an interrupt if a defined threshold exceeds?I need a clarificatio...

How to clear the SPI RX FIFO (register mode)

Hi all, I have an issue. I need to see the Slaves free space, for that, I am reading the slave's Empty space, and based on the results I send the data points which needed. but I am having a big issue. it always has a one execution cycle delay. For ex...

I have code on L4 series that i want to run on L0 series. what are the changes and where that changes i have to make in order to make code runnable. I think with STM32 back word compatibility is there can any one guide me how to do that.

BlueNRG_LP multiple channel ADC

I am working with BlueNRG LP.I am acquiring 3 channels:ADC_VINP0 (PB3)ADC_VINM0 (PB2)BATTERY.I used and modified example of the "BlueNRG-LP Navigator" ADC_DMA.I read ADC_VINP0 and the batteries but ADC_VINM0 not work!! ( I used STEVAL-IDB011V1 and i ...

Hi im working on stm32l072cbt6 micro controller im trying to read the adc value on channel1 in polling method i generated the code using stm32 cube ide,the issue is that always i could not se any variation in the adc raw values and my code is as below,

void MX_ADC_Init(void) {   /* USER CODE BEGIN ADC_Init 0 */   /* USER CODE END ADC_Init 0 */   ADC_ChannelConfTypeDef sConfig = {0};   /* USER CODE BEGIN ADC_Init 1 */   /* USER CODE END ADC_Init 1 */ /** Configure the global features of ...

USART running 7N1. My STM32F429 must interface an old modbus system running 7N1 on a RS422 bus, as slave. However, I can't see how to setup the STM32 as 7bit, NONE, 1 stopbit - not in Qube, not be registeres direct. Is this true ?

Help in writing a bare metal code for implementing a UART RX interrupt routine in SMT32F767ZI ?

I started writing embedded code 7 months back for a robotics project. Till now , I was able to handle most of the stuff with HAL libraries. I hit a snag when trying to interface with a AHRS(Microstrain CX5-25) unit. There were time when only first fe...

How to calibrate ( RTC )LSE Crystal by temperature ?

I ' ve been working on a device that able to use industrial area. I must be sure that rtc clock is accurate because this device need to use RTC too much. When i researched , i did not find any code example about rtc calibration by temperature. Any su...
