Hi, I'm using STM32L0 series and working on UART to communicate with other module and I had chosen the polling method because i know the device max response time and exact data what i'm going to receive. I was running my application for testing and i...
Good morning at all.Is it possible to split ADC channels by using DMA and by POLLING them manually?I'd like to sample 17 channels by DMA in continous conversion and then poll one channel manually which is MUXed with external IC to different analog si...
I use on STM32H743ZI-Nucleo PG0 as GPIO interrupt with Falling Edge. It works, I get INT triggered, but:an INT is also triggered - sometimes (once every 1000 falling edges) - on a raising edge. After several tests I am sure, this PG0 EXTI0 is randoml...
I am aware of the TIMER4 ADC_EXTERNALTRIG_T4_TRGO definition bug and have modified the file accordinginly . I have had this code working in single channel mode ( non DMA) but cannot get it working in multichannel DMA mode .ADC_INIT() { hadc3.Insta...
Vref is giving - 5200- 5700 mv but my source is (3300) maxVBAT - 3600 mvTemp- 170 degreesnot able to get why it giving that difference and my configurations are as per the example cube libraryNote: my Vref value is using as VREFANALOG_VOLTAGE for VB...
Before starting the blinking program, when I plugged in my PC USB to micro the user LED's (1-3) could be toggled when I hit the blue push button, now they can't.Within Kiel, I started a new project LED blink. I found my MCU (as seen in the image), th...
I received my Discovery board a week ago and still I can't load any examples. I can run a new project (I followed a tutorial) without problems, but when I try to import examples such as the 'audio playback and record' I can't build the project, debug...
Hello,In the datasheet for the STM32F423 , I see at the table 18 "Features depending on Power Supply range". I want to understand what will be the performance of the MCU if I power it with 1.8 V. I don't clearly understand the table. At the column ...
Hello,I am using the XIP functionalities over QSPI on the EvalBoard STM32F7308-DK. I got the launcher working without problems (jump to 0x90000000U, which is the QSPI base address). I also got a basic demo (toggle led) working from the external QSPI....
I tried to sort through the manual. When I choose external clock do i actually connect anything to the PH0 and PH1 pins and what kind of oscillator.I see that there is already what looks like 8 MHz crystal is this one I am connecting when using exter...
