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...
HiI use hal functions HAL_RTC_SetTime and HAL_RTC_SetDate for set date and time in RTS.After set date and time RTC works correctly.Problem appiars after reset.After reset time and date read by functions HAL_RTC_GetTime and HAL_RTC_GetDate don't corre...
Hello,I need to generate a Manchester Encoded bitstream from one of the GPIO of STM32F4 with a data rate higher than 1 Mbps. Is it possible to do so? If yes, how can I do so?
