I have a water flow rate sensor which I want to read with my STM32F411RE Nucleo-64 board. The output signal is a frequency. How can I read the signal? The sensor has following properties:Flow Range = 1 - 15 L/minPulses per Liter = 2200Frequency Outpu...
I'm working on a project that a series of duty cycles must be measured. A sample of related waveforms is displayed below: As you can see from the signal, the frequency is too high, and calculating it using bit functions is impossible. In the controll...
Even im getting Rec error / Event error .. how to resolve this error ?
I'm trying to clean up some code I used to figure out how to use the UARTs on a STM32H7A3. The STM examples declares the data to be sent out like this:ALIGN_32BYTES(uint8_t txBuffer[]) = " *****UART_TwoBoards comm ... ";ALIGN_32BYTES is defined like ...
I'm using STM32F303 to sampling the multiple analog signals, and for higher resolution, I was oversampling every channel, but I found out all the signals were ramping with same period and same time. For figuring out the problem, I did a lot of tests...
I am currently using an STM32G474QE for a motor control application and ran into a possible silicon bug.We have ADC1 and ADC2 configured for dual regular interleaved mode with DMA triggered off TIM1_TRGO2ADC3 and ADC4 configured for dual regular inte...
I am trying to make UART boot loader and programming via Teraterm by sending HEX file.some hex records have only 4 bytes. how to program only one word. Reference manual RM0454 page no. 59 says only double word can be programmed.How to program single ...
Is there any function or library associated with STM32 Device to convert the UTC time to Local Time and Vice versa ?
I wanted to use RTC in both my cores M7 and M4. Is RTC a shared peripheral ? Can we use RTC to set or get time from any core asynchronously ? Please share any configuration need to be done for doing so ?
I'm configuring I2C4 as a slave receiver, using interrupt method. I noticed that when the I2C master (another MCU) sends the slave address, I2C4 detects an address match and sets the ADDR flag in the I2C4->ISR register. What baffles me is that at thi...
