What would be an efficient, low latency way to reflect the state of an input pin onto an output pin?Is there anything more automated than configuring the input pin as an EXTI, then in the interrupt handler, reading it and setting the state of the out...
Hello,as I see at the AN5200 only in DS and HS the signal level is 3.3V.Does it mean that the IO signal level in SDR50 for example will be 1.8V on the host side?The MCU has internal LDO for it ?Or the host size is always 3.3V, and the signal voltage ...
Hello,I was searching in every STM32 CubeMX pack examples for ADC DMA with Double / Multiple Buffering. But I found nothing.I found in dma_ex hal file the functions like HAL_DMAEx_MultiBufferStart (or HAL_DMAEx_MultiBufferStart_IT), but they aren't u...
I want to do i2c writes > 255 bytes using DMA with an STM32L451, but fail to use the I2C_CR2_RELOAD flag properly it seems.I end up with an address byte when the transmission continues.How should it be done using the raw register defines.Currently I...
This page says:"With a custom main() on Arduino, do not return from main(). As there is no operating system running on a standard Arduino, there is no where to return to. If you do return, abort() is called, then exit(). On the AVR-8 MCU ( Uno, Mega ...
Question is about QSPI in stm32H743.It seems that indirect read mode and indirect write mode should behave the same if it sends only the instruction and the data is absent.But I don't receive interrupts in case of indirect mode read without data, whi...
The point is that when you press a button, an LED should flash three times.If you press the button again while it is flashing, the LED must flash 3 times again.The whole thing should be implemented without blocking code.I could could use a loop to ma...
Dear ST Hello,I have a big problem with floating point calculations,I am trying to implement the IIR filter to filter a current but the result is Zero.Sometimes the watch expression window shows me 0 but the input filter is not zero. /* Get the HImax...
