Hi allI'm configuring STM32U5A5VJT to work with the USB HS crystaless. From the Cube it seems to be possibile to use one of the integrated oscillators as clock source for the USB HS but this is not mentioned in the datasheet.I'm afraid that it could ...
Hello,I'm looking the vector table described in the Table 97 of the STM32G4 series reference manual, and it shows interrupts with different characteristics, such as TIM1_BRK/TIM15 and TIM6_DACUNDER, being allocated to the same address. This is very c...
I having trouble getting the correct CAN timing configured with default 96Mhz System Clock on the NUCLEO-F412ZG eval board. I need a 250kbit/s baud rate. Here is what I have so far. The system clock setup is below.
Hello,I setup a USB virtual com port which I use for serial comm. My design has 2 boards; a panel-board and main-board. The main-board has an STM32F373 with a USB-C connector as well as ESD321DYAR diodes for DM and DP USB line protection.The main-b...
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...
