It is not very clearly writen how to use external SMPS.Do I need to set any registers or anything like that ?My system will run at 81MHz, and i want to reduce power consumption. I have DCDC and Switch control. IT looks like enabling DC/DC reduces cur...
I'm new to Cortex-M, STM chips, and the STM32L4R5 in particular, and am having problems getting this working. I have used ARM chips (since ARM2 :-), Atmel <x|mega>AVR and the Raspberry Pi Cortex-A chips...I seem to be the only person who prefers asse...
Hi,I am triying to use the standby mode and save some data into EEPROM memory, but when i start the erase eeprom process before to save data, my program is blocked. I think that my code have a 89% of flash size and eeprom area have a program code.I n...
Good afternoon,I have developed my application based on STM32L4 family. Application is working fine on my custom board but I have a doubt when debugging the board usign ULINK2 tool with Keil: when I debug the board, and I have a look to 'Watch' windo...
Hello, I'm using the STM32L451VC microcontroller to perform a communication through I2C protocol to a programmable resistor (AD5272). It is working well when I do a NRST to the microcontroller, but when I start the program from the batteries (without...
Hi all,I'm new with the PWM business, so, I'm referring the sample code (TIM_PWM_Input) provided in STM32F2XX stranded peripheral library . In the readme.txt file it is mentioned that we can measure minimum 915Hz frequency. But in my application, I w...
I am working with the STM32F446 microcontroller and I need to detect when a 50 Hz (plus-minus 2 Hz) square wave signal is turned on and off, respectively. The signal is connected to a pin that has TIMx_CHy alternate functionality. Is there a way to a...
I'm new user running a STM32F767ZI Nucleo board.I need to build very simple application that copied array[2] to GPIO Pin (PC6) by DMA in "memory to peripheral" mode.I interested to activate DMA in two modes:a) Don't use timer (memory to GPIO by DMA p...
I am using the DfuSe demo application version 3.0.6Image-1 DfuSe demo applicationI have observed that if existing firmware (Already loaded firmware before reprogramming) in my STM32 uC based custom target-board is not read-protected then I can be abl...
I have a STM32H753 with 16MByte, 32bit SDRAM and a Wiznet W5300 in 16bit mode (acts as SRAM Bank 1, SRAM_BANK_ADDR = 0x60000000).So, if I read a Memory cell:uint16_t aw = *(volatile uint16_t*)(SRAM_BANK_ADDR);all is ok. With a scope on NE1, NOE, NW...
