Hi STM community,I have created stm32 project in STMCubeIDE. I2S2 configured as Half duplex Master in receive mode, 16k audio frequency and 24 bit on 32 bit format. Able to receive data in polling mode.But not able to receive data in SRAM1 memory ...
I am trying to use DMA to capture data in the background (from ADC) while I use PWM to control 2 motors. When I use DMA to capture the ADC values from my sensors it works fine. When I only use my PWM timers (without DMA in the background) the PWM wor...
I once read that when waking up a microcontroller from any low power mode, it will start as we have pressed the reset button, but, the reference manual says this: "After waking up from Standby mode, program execution restarts in the same way as after...
We are porting applications from STM32F1 to STM32F427 MCU. Currently, we are not explicitly configuring SCB->CCR unaligned trap, based on ARM M4 manual, LDR, VLDR always triggers the fault if the address is not aligned properly.Do I require to use me...
I try to start RTC in my STM32F429 (I do not use HAL libraries and I want not to use it). I use registers directly or with use of libopencm3. I want to run RTC and Wakeup timer with LSI source now and the RTC_TR is always 0 and RTC_DR 00002101h (and ...
Hello Dear Friends,I am looking for using multiple ADC channels on STM32f429IGT6, but the problem is the code I have generated so far only converts its first input and the rest of the channels are not converted. I hope experts here can help me. Here ...
I have 7 binary variable that I want to continously send to uart with the DMA.I do not want to use ascii format, I want to send binary data.If I use multiple DMA transmits in a row, just some are beeing send due to the fact, that when the second is t...
Let's say you're loading the SAI 32-bit ADR or BDR data registers. Using 24-bit data size, I2S protocol. More concretely, what values do you load for 0 amplitude, max positive, and max negative?Do you center it? Eg map 0 amplitude to 2^32 / 2, max po...

We are using battery Litium ion one-cell.Voltage of cell is between 3.3V to 4.5V.We want to calculate battery voltage.Is it possible to put 4.5V to pin of MCU (STM32L452) ?
