STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi!I would like to make a wav. player using STM32 microcontroller. My first step was to generate a sine wave using STM32F103C8T6, SPI interface and external DAC MCP4921. However, it's not working.I attach the schematic of my device.I wrote 2 versions...
This should be straightforward but I cant get it to work. I simply want to control the GPIO output of pin PG10 on the STM32F769I-EVAL board. I have removed all daughter cards, LCD and the Micro SD card. According to the datasheet, PG10 is connected t...
Hello, I am trying to use DMA with USART to transmit and receive data to buffers in internal RAM.I setup my DMA1_Stream4 as USART3_TX. However, after setting DMA control register, Peripheral address, memory address, number of data to transfer, Enabli...
We welcome everyoneIs there a way to protect uart from being hacked!?For example:I have a device that uses gsm to send sensitive data.Anyone with a simple background can learn the uart pins and then put a logic analyzer or rx probe and then know ip a...
Hi There,the goal is to get data from an MCU via I2C to a Raspberry Pi. I already have this working with ATMegas but would like to move to the STM32 Platfrom.Seems I'm quite spoiled as all I needed to get I2C working was this:void sendData(){ byte ...
We encountered a big issue with the ADC's in a project.The G4 device has 4 ADC's configured (ADC1, ADC2. ADC3, ADC5).ADC1 and ADC2 are sampled simultanious and triggered by HRTIMER1A interrupt with 4 channels each.ADC3 and ADC5 are in independent mod...
1. can I use FMC to interface with any kind data address oe cs device? 2. The device is not SDRAM or flash or any kind of memory, Does anybody have an experience with that? 3.The device is from the early 90's and works with 5V logic level, Can I use ...
I'm trying to transmit a newer data while the previous transmit interrupt hasn't finished, I simply just call HAL_UART_Transmit_IT again and the result is the first called interrupt will finish its whole job and the second call do nothing, I know the...
I have this scenario:My stm32f0 implements a I2C slave, and I have a raspberrypi with i2ctools as a master.I define a bunch of 16bit wide registers to access in the stm32.Now I wanted to test what happens if the master only reads 1 byte instead of 2 ...
HiFor STM32L4R5QII6 is there any way that we can control GPIO i.e., PF15 pin when the MCU is in Shutdown state. Do we need to have any pull-up for those GPIOs which need to be controlled?
