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...
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?
Dear community,once again I am asking for your kind help. I want to implement a simple timer interrupt as a time basis on my STM32F407. I configured Timer11 and it seems to count as I expected (as far as my debugger can tell me). When the counter hit...
