I want to use a periodic timer to trigger an ADC conversion (which uses DMA).I have the periodic timer working OK on its own, and the ADC conversion with DMA working on its own... but when I try to put the two together it doesn't seem to trigger the ...
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...
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...
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...
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...
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...
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...
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...
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...
