Resolved! How to learn fft?
Can you help me with fft? I don't know exactly how to use it. my goal is to separate the different frequencies.can you share sample code.
Resolved! Hi Everyone, For the past 9 months approximately, we have been working on migrating our custom mcu (stm32L496vg) from a PIC mcu. Currently, we have 2 of our custom boards connected via SPI with one as the master and the other being the slave.
The connections are quite simple Master-CLK , Master->MOSI to Slave->MISO and we only have one Slave so, we aren't using CS. We're only trying to receive simple data but, we're only getting various trash. We have experienced crashing and the clock si...
Resolved! STM32F0 backup registers are not supported neither by HAL nor by LL drivers. Why is that?
In addition neither the datasheet nor the reference manual mention how to access it but the older (pre HAL era) driver versions did support this. The backup registers are even missing in the RTC register map of the reference manual even though these ...
UART IRQ_Handler will not Flush RDR Register when Receiver is not Enabled(no call to HAL_UART_Receive_IT() )
HiI had a Problem with the HAL UART driver. On my Custom Board with STM32H7 the TX and RX Pin are connected together, so i have a local echo and read back everything i transmitt. My Problem now is that it will generate a Receive interrupt but don't f...
Resolved! What constitutes the 16 in the baud rate equation?
Hi ,all.I wanted to understand where the 16 in this equation comes from, cna anyone epxlain?

Can the ADC regular channel and injected channel of STM32G4 not be used at the same time? Is this a bug?
I use cubemx (6.0.0) to generate ADC1 configuration code, for example, ADC1 channels 1, 2, and 3 are injection channels, and TIM1 channel 4 is used to trigger, and ADC1’s 4, 5 are Regular channel. STM32F4 can work very well. But STM32G4 does not wor...
