Hi ,I have been testing STPM33 power offset calibration.It seems not working as per the Calibration application note.The document says we need to write offset values to offset register in the sensor and then the read power will be substracting that o...
I'm building SPI slave based on STM32F750V8T6 MCU and I'm having problem loosing sync between master and slave. When I run test that is sending sync bytes, slave receive data from master, sync again and slave is returning data after some time master ...
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 ...
