Hi guys.I am using STM32F401VEH6 to read the peak value of a waveform like sinewave.but the value drifts about 40LSB time to time.I connected VDDA to Vref+ and seperated from VDD.(based on Application Note recomandation)But when I checked the datashe...

Hi All.I am building a function using ADC with DMA.what i did in the while loop is just toggling a GPIO Pin.but it seems that the while loop will be interrupted when ADC is triggered.does it means that when ADC is triggered, while loop will be stoppe...

Hi guys.I have 2 GPIOs, one is used as a PWM, the other one is used as ADC.and the peak comes in the falling edge of the PWM singal.and the plus width is only like 2us.I want to get the value of the peak voltage using ADC.The problem is, if I use a i...

Dear allI am trying to access my SD card using SPI, I tried the code below but I couldn't get it work.is there any official tutorial about SD card of NUCLEO-L476RG?SD CARD Info: 32GB, SDHC, FAT formathttps://github.com/eziya/STM32_SPI_SDCARD

thanks for your answer.Measurement errors can have a wide variety of causes, which AN2834 covers in detail. →AN2834 Fig 20 provide 2 different connections.and I used the right one。VDD = 3.3V, VDDA = Vref+ = 1.8V, VSS=VSSAAnd I am using UFBGA packag...

Hi grestm.I need to use the value of the peak voltage in my algorithm.i know the exact timing of the peak voltage shows, but cannot manage to messure it due to the siganl frequency is about 500k.

@GChir.2 Hi. thanks for the code.still failed.this is the info I got from serial comm.ERROR in mounting SD CARD...Total Drive Space: 2147481600 KiB (2047.997 GiB)Space Available: 0 KiB (0.000 GiB)ERROR!!! No. 1 in creating file *Test.txt*ERROR!...

@GChir.2 I am looking forward to that because I tried another module, still failed.
