Hi,I am using a STM32L4ZIT6 MCU. I want to monitor 4.2V Lipo battery voltage on an ADC pin. I have experimented two approaches:First:I used a 332k - 820k divider in order to drain low queiescent current. This is an high impendance measurement, where ...
I am using two STM32F405's to read a switch and have some diagnostics.I interface this to an analog input on one MCU and a digital input (no pull up/down) on another MCU.However, I have cross-talk with the neighboring analog channels and more severe,...
This is one that baffles me:I set up Timer 8, and everything haasworking perfect. Then i did set up interrupt on some pins, and then the PWM signal on timer 8 stopped working.This is what i did, so the Timer 8 stopped working:Edit: Only with the pull...
All: I have connected internal temperature to ADC3, and I am able to display degrees C on "Live Expressions". The particular chip we are working with has an operating range of -40 C to + 85 C. If I am monitoring the internal temperature on a regular...
I am programming stm32h750 microcontroller.I managed to make work ADC2.ADC1 and ADC3 gives wrong results sometimes when change priority at DMA interruptI have programmed the ADC3 using DMA2 (not BDMA that not generates interrupts to me)Sometimes firs...
Hi,I hope somebody can explain the following behavior:I use a NUCLEO-G474RE board for I2C testing. I have an external I2C slave which provides the required pull-ups for SDA/SCL when it's powered.Now my STM32 started with connected but not powered I2C...
Dear all,I have the STM32F469 discovery kit which is working. I want to use the STM32F469 to drive a 4" tft lcd screen using its 31 pin mipi connector. The goal is to get a gauge displayed on it, I was thinking of using LVGL to design the GUI.I have ...
Hello,I updated my stm32 project because I had problem on the older version. So I updated the Time.ioc by migrating version... ...but when I open the system clock configuration I see that it's not the same configuration for "To Ethernet PTP". For in...
Hi,I have purchased a sensor expansion board (X-NUCLEO-IKS4A1) for my board (NUCLEO - F446ZE). However, when I wanted to display the data on Unicleo-GUI, the GUI cannot detect anything, not even my firmware. I looked through the datasheet for Unicleo...
Hi Team,We are working on the locomotive-based custom product design where we are using the STM32L452REY6 microcontroller. We have one requirement to update the STM32L452REY6 firmware using the internal bootloader over the UART.We have referred follo...
