Hi allI have an IIR filter design with 7 coefficients. (For feed-forward and for feed-back)Regularly all the coeffs are between -1 to +1So I Just multiply each by 2^15 to get it in q1.15 format.However, now, the feedforward coeffs are very small (0.0...
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.
Greetings,In my application i have initialized STM32F205RG with USB High Speed Host for detecting USB Key board and I2C2 for communicating with DS3231 RTC Module. RTC module works prefectly when i don't initialize USB HS peripheral, but when both ini...
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?
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...
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...
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...
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...
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...
