Hallo everyone,As engineer who started to explore the world of MCU's years after my retirement, I regularly encounter problems that puzzle me for some time. However, since I'm stuck for several days now, I decided to ask for assistance by this forum....
Is it possible to make HAL_ADCEx_EndOfSamplingCallback fire when ADC is running in the dual mode with DMA .More specifically: On a NUCLEO-H723ZG, the ADC is started by HAL_ADCEx_MultiModeStart_DMA() and ADC2 is a slave to ADC1. The ADC conversion is ...
I've been reading about GPIO and what can be triggered. I see an event can be triggered. Events can be connected to peripherals to have some control without the CPU intervening. I can't find good documentation showing how to connect or effect periphe...
I need to build an MQTT demo from scratch using STM32CubeIDE where the STM32 board will act as the publisher and Adafruit IO will act as the subscriber. I want to implement this without using FreeRTOS and LwIP, focusing only on publishing the message...
Been trying to get an test application working on a STM32F469NIH Discovery board.Should be fairly simple - Write a file to the SD Card, with FatFS, the read back:Try as I might, I couldn't get things working.After a bit of debugging, I think the issu...
Dear Team, I need your help for configuring BLE on B-L4S5I-IOT01A board. I got some example BLE in B-L475I-IOT01A.But it is different from that board could you please help me to configure and use Bluetooth via .ioc file.
The motive is to upgrade the firmware of STM32L031xx using the system bootloader. I am facing 2 issues majorly.1. For this I need to go to boot mode and boot from system memory as per my understanding. STM32L031K6T6 is follows pattern 2 for which the...
Dear A.Ziru,Apparently I'm having the same problem as you when trying to receive MIDI data from a USB device (in this case it's a guitar multi-effects pedalboard). How did you solve the problem? Where and how did you defined that MIDI class descripto...
Hello,I am trying to implement a USB HID keyboard on an STM32F042 without HAL or LL, just simple register defs. I took an example code generated in CubeIDE with HAL and a few other examples. I extended the example with HAL to also implement the LEDs ...
I'm using TIM1 to write a DMA buffer to the built-in LED. I'm trying to get the Transfer Complete callback to trigger. I've tried setting hdma->XferCpltCallback to a function. I suspect there is an interrupt enable flag I need to set and probably cle...
