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...
Hello everybody,I wanted to measure the duty cycle (tone) of a PWM signal with input capture mode. Unfortunately, it works only almost up to 65% of the duty cycle(Ton). otherwise will the T_off measured instead of Ton. does anyone have an idea what c...
Hello all,In my Project i m using stm32l031k6t6 microcontroller interfaced with GSM and GPS module and external FLASH memory.For that , first controller read coordinates information from GSM and GPS module and store it into flash memory for record. a...
