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...
The site https://www.stm32-c2c.com/ as far as I can tell is no longer supported.
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...
