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) ?
Hi everyone, hope all of you are doing well.Posting here again about the ADC. I finally got the ADC out of that over run situation and now ready to acquire data!The way the ADC is setup is by having 4 channels using Pins setup as continuous scanningP...
I am using the above Timer as both a debounce of 50ms and as a PWM for the on board LED. Basically I hit the user button, debounce for 50ms. While button held PWM to the LED of 1/2 sec on, 1/2 sec off.....Release button and PWM stops.The timer is run...
Can someone tell me when I useuint16_t temp; temp = __HAL_TIM_GET_COUNTER(&htim2);the above why temp doesn't equal the TIM2 CNT register in the debugger? I've also triedtemp = htim2.Instance->CNT;
