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?
I cannot get debugging working through the STM32CubeIDE. I can program the device using the OpenOCD debugger (but stepping through the code gives an error). However, I want to use the ST-LINK GDB server as the debugger, which does not work. I receive...
I am having a tough time getting a valid temperature reading from my STM32L051K8U6 MCU. This should be an easy task. I've spent a LOT of time Googling and believe I have everything setup correctly. Most of the sample code online is identical, but it ...
I'm trying to allocate 768KB For the Flash for the user program. at address 0x08000000And also save constant data starting from address 0x08100000 consuming 1024 K bytesNow from my understanding I should have free space for example sector 10,11.I'm t...
Posted on December 01, 2017 at 21:45I recently generated code for a project using STM32CubeMX which used mixed LL and HAL drivers (HAL only for USB). At the beginning of main the generated code calls HAL_Init, which is all well and good, but then la...
Hi,I am using KEIL to program PA5 pin which is connected to the user LED. But after writing the program, I am unable to get the LED on. It is a simple program but I am not sure, why it is not working. Any help will be appreciated. #include "stm32l0xx...
