Read flow rate sensor with STM32F411RE Nucleo - Timer Interrupts
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...
Resolved! Calculating pulse width (duty cycle) using stm32 DMA. Is it possible?
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...
Currently Im working with BMS Module .. Battery is sending CAN Messages at Slow rate.. Conroller is taking few bytes of Recieved bytes, Sending back with diffrent ID's .. Some where Transmitting speed is more than the Recieving speed.. Synch ?
Even im getting Rec error / Event error .. how to resolve this error ?
Resolved! How do I declare an array of structs with one element a byte aligned array of uint8_t
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 ...
ADC oversampling result ramping in seconds
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...
[POSSIBLE SILICON BUG] STM32G474QE Analog Sequencer on ADC4 Slips by one when configured for dual regular mode with DMA under specific trigger settings and high noise on inputs.
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...
Resolved! Single word (32 bit ) Flash programming STM32G0
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 ...
Resolved! Function/Library to convert between UTC time and Local Time
Is there any function or library associated with STM32 Device to convert the UTC time to Local Time and Vice versa ?
Resolved! STM32H7 RTC in both M7 and M4 Dual Cores
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 ?
