Resolved! the Maximum value for RC filter
If ADC1 is continous mode, what's the maximum value for R14? I think the higher the R14 the better, but if too high, the ADC1 value may lower than real.

Hello GaysI'm trying to read the gyroscope ICM 20948, specifically register 51, but I'm not getting anything. Can someone take a look and give me some suggestions?
Resolved! what if PA2=5V in analog mode?
I can c in RM0033 (Rev9) Figure 18, that PA2 is connected with low impedance to a diode to V_DD, if PA2 is configured as analog input...In Doc ID 15818 Rev 9 I see that R_ADC is at least 1.5kR...If I connect PA2 in analog mode directly to 5V: Would I...
Resolved! VDD12DSI pins in STM32H747BIT6
Hello everyone,I am working on a system based on the STM32H747BIT6 MCU and do not plan to use the DSI interface. I have searched through various forums but still have some doubts about the proper power pin configuration when DSI is not in use. Here i...
Resolved! can't connect to STM32F407IGT6 on custom board
I have a custom board based on the STM32F407IGT6 and I'm having trouble connecting via ST-Link (v2 clone) using STM32CubeProgrammer. It seems st-link unable to find the target mcu. I checked all SWDIO, SWCLK, NRST, VDD, GND connections with a multime...
How to use USART single wire(half-duplex) for SDI-12 communication protocol using Stm32cubeIDE???
Hello,I am trying to communicate with an SDI-12 sensor using STM32L072CZY6TR. I'm using UART half-duplex with the following configuration:Baud rate: 1200Word length: 7 bitsParity: EvenStop bits: 1My questions:Do I need a UART to SDI-12 converter modu...
How to sample improve ADC speed?
My application senario: sample the sensor signal every second, and transmit through UART. to save power supply, I select ADC single mode, and used average as filter.void ConfigureADC(void) { ADC1->CFGR1 |= ADC_CFGR1_AUTOFF; ADC1->CFGR2 = (ADC1->CFGR2...
