My Question: If the opamp output multiplexer is configured to connect the output pin (OPAINTOEN set to zero) then can I still use the ADC to read the opamp output?The wording in the reference manual is ambiguous – it implies that the output is either...
Hi,Looks like I cannot get the wd over a ~22 seconds watch time .I would like the watchdog to bark every 60 seconds or more.The 303 header file specify the reload max 0xFFF and as well the window, though they are 32bit values .Also the max prescaler ...

Hello,for a measurement task, I have to perform an ADC readout a certain time after a rising edge occurs from an external device.My idea was to use the HRTIM with an external event but I am unsure if it is possible to trigger a timer start with an EE...
Hi all,i succesfully tested USB HOST drivers in standalone mode on a Nucleo-F746ZG.In my application i need to use CMSIS, but i can't figure out how to make it work. I am using the same application that i use on the standalone mode but this time i pl...
Using NUCLEO-G071RB board and therein DAC_OUT1, PA4, CN8.3.Use internal Vref with 2500 mV.Calculating DOR from a dst_voltage using equation in Reference Manual (page 360/1223) DOR = DACoutput * 4096 / Vref gives voltages3..5 mV too high, e.g.// 4...
I am trying us STM32H745XI controller in my design, I want some clarification in the power supply section. In Reference manual en.DM00176879->section 7.Power control (PWR) ->Figure22->4.External SMPS Supply, Supplies LDO. I am not understanding how t...
Hi ,My Requirement is communication between micro controller and Serial terminal(putty) using UART Communication.I have taken example project of UART( two board communication using DMA)...i have defined #define TRANMIT_BOARD 1. but I am not able to c...
Greetings,right know we are evaluating some strategies to reduces overall power consumption of our product, including two STM32H743 microcontrollers.Due some other design restrictions the following options are not feasible:Switch to a low power µCUse...
Hello every one.I am working with the STM32L4R5ZI. By default, it will uses MSI as the system clock source at 4Mhz.My question is: what will happen if I turn on HSI or/and HSE without turning the other clock source off?Thank you in advance?
