Problem With Mpu6050 I2C.
Hi.I am trying to communicate with MPU6050 through I2C protocol. I am using STM32f103VE.The problem I have, is that after start condition and transmitting slave address and slave internal register address, and then starting again,this time with slave...
SIZE of stm32f469ai microcontroller
i am working with STM32F469AI microcontroller interface with the STEVAL-IDP005V1 industrial sensor, when i interface STM32F401RE and STEVAL-IDP005V1 through ST-LINK the disk size shows 520kb is free of 540kb, but the flash memory size of STM32F401R...
TIMER2 interrupt not working .
I am trying to blink an led on stm32l476rg nucleo board using CMSIS core and startup file in Keil.I am able to run the Timer2 ,it runs untill it overflows .After overflowing I am trying to clear the SR register in the Timer2 interrupt but after the t...
UART1 issue with STM32F303
Hi All,I am trying to receive data on USART1 but I am not getting data on USART1. Apart from USART1 USART2 & 3 is working fine.As per datasheet USART1 pins are showing on (PE1, PE0 or PC5 & PC4). When I am use PE1 & PE0 that time USART1 is not workin...
adc example on stm32f407vg
i am using stm32f407vg board and trying to run a adc example (adc with dma ) from stm32f4 discovery board examples (en.stsw-stm32068) and when i run this example and try to debug the variable adcconverted value and conversionvalue i am getting a valu...
erasing flash stm32f779ii
I'm trying to erase sectors 11,12 in the STM32F779II, I have been running into that problem for one week without a solution.So Right now I'm trying to check if there is ANY write protection on sectors 11,12. But There is NO write Protection error.How...
Is GPIO Ports RCC->AHBENR.IOPxEN required to be set to allow AF functions to operate.
Am trying to reduce the power consumption for STM32F0xx & G0xx applications.Reading the documentation it is not clear if I can disable a AHBENR.IOPxEN bit in the RCC blockonce a port is configured and still retain any GPIO port Alternate Functionalit...
SPI Rx double buffered DMA triggered from a GPIO
Using an STM32H743Zi I'm trying to receive 32bits of data from two SPI interfaces triggered at the same time from an external GPIO at a fairly high rate e.g. ~200kHz. Trying to use double buffered DMA receive.I started by trying to get an external GP...
Why the current measured form the microcontroller(Stm64 Nucleo L433RC- LPSleep mode) differ from the current value written in the datasheet?
I am using STM32L433RC -p microcontroller for current measurement. The current in the microcontroller was measured using X Nucleo LPM01A module.I was doing current measurement for Low Power Mode(Low Power Sleep Mode).The current value given in the da...
