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...
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...
I want to i2c to communicate two STM32F103. one of them will be a slave and other will be master. But program is stop on this : void SendI2CByteData (I2C_TypeDef* I2Cx, uint8_t SlaveAddr, uint8_t Data){ __IO uint8_t temp = 0; I2C_GenerateSTART(I2Cx, ...
Hi.First of all, the essence of my problem is already described here - https://community.st.com/s/question/0D50X00009XkiXu/spi-dma-data-corruption?t=1567119350874In my case bug happens randomly and not very often. It could be one corrupted transactio...
Would like to generate a 100 Hz sine signal using DAC1, channel 1 (PA4, G071 NUCLEO @ CN8.3).Would like to use TIM2 to trigger the DAC and DMA to feed the DAC.But am not successful. TIM2 is running, but DAC is not fed.Please have al look at the (bare...
I have two blackpill boards with STM32F103C6 MCU's on them, I want to explore using can bus between those two units and am wondering if I need to add termination to the cables or if those pins are internally terminated when configured for CAN.All the...
