Hi, I am trying to implement printf with UART using DMA. The problem is when i use consecutive printf's in my code, transmission of the first data is not being waited. I implemented a control block to check if the transmission is completed but it doe...
Hello,I need to power the NucleoF103 development board using an external 3.3V power supply. I have read in the NucleoF103 manual that this is possible by removing SB2 (to disconnect the voltage regulator output) and SB12 (to disconnect NRST). I also ...
Hi. I am using STM32L010C6tx processor. I drew the circuit myself. I did SYS-> debug serial wire. I was able to install without any problem. But sometimes "Memory Programming...Opening and parsing file: ST-LINK_GDB_server_a14408.srec File : ST-LINK_G...
I'm developing a board with an STM32L452 and would like to find out if I can low the power consumption.The current draining is 35mA, my goal is lower it to 20mA or less to achieve a requirement.I've tried putting the device to sleep putting SLEEP MOD...
I want to receive the data from one nucleo board through CAN protocol and it should trigger the DMA and shuffle the received data and transmit back again to another board.In ioc configuration I am unable to enable the DMA (peripheral to memory and vi...
Hi Team,We have an LCD with a MIPI display. We need to connect with the STM32 MCU.Please find the pin details on the LCD. We need to connect MIPI_0+, MIPI_1+, MIPI_2+, MIPI_3+, MIPI_4+,MIPI_0+, MIPI_1-,MIPI_2-, MIPI_3-, MIPI_4-.Kindly suggest ST cont...
Hi all,I am having some problems connecting a comparator to a TIMER using its blanking function (as described in the AN4232 application note).I've read the COMP_OutputBlanking example found in the STM32G4 repository projects (I'm using a STM32G431).I...
Hi,I am working with STM32G491RE.I communicating ATM90E26 single phase energy meter with STM32 through SPI communication.I can able to read voltage ,current values correctly from the meter.For KWH calculation, I am reading Absolute active energy reg...
Hello there, I am working on a project using an STM3240G-EVAL board which as the STM32407IGH6 MCU on it. In this project, I want to use USB-OTG-FS to connect an external USB microphone to the board and then store any information sent into the micro...
Hello, i am trying to read internal temperature and vref values from ADC3. I shared ADC3 ioc settings. ADC clock mux freq is 96MHz and sampling time is set to ADC3_SAMPLETIME_247CYCLES_5.On init routine calibration line as below :HAL_ADCEx_Calibratio...
