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 is a minor thing, but.... STM32L433xx/STM32L443xx Errata sheet, ES0318, revision 4, section 2.1.2 on VDIV/VSQRT says there are two work possible arounds, but then lists the same work around 2 times (disable lazy FPU context save). What is the ...
I'm using a Nucleo-H743ZI and have configured ADC3 to trigger off of TIM3. It is scanning 4 channels every 10 us. I also have BDMA configured for the ADC. The ADC end-of-scan interrupt is occurring every 10 us, but the DMA interrupt is only occurr...
I just received version 2 of a board I designed. It has two STM32F427 on it. One a 144 pin used for main processing and the second a 100 pin used to control IO.The 100 pin MCU uses Ports B, D, E (all as outputs) to control outputs.Version 2 of the ...
Hi Guys,I working on a project that require measure time difference between 2 PWM (Refer the picture below) . I was able to measure the PWM frequency using input capture method but not able to measure the time difference, Td between 2 PWM. Kindly nee...
So why this issue in the STM32L1 discovery board.I also uploaded images regarding the problem in the board.
I see that some libraries from the SDK (Like the PLL State Observer) are delivered as precompiled objects for each of the supported IDE's. Is it possible to obtain the source code of these libraries in order to use them in our project's IDE? (Since w...
Hi, I am learning how to use Uart and created a simple example project where I sent 'hello world'. i then use RealTerm to view this message. i have generated this project using CubeMX and it works however i flashed the board once and after that i can...
Hi Community,I try to develop my first test app for the STM32F69i board. I got STM32CubeIDE environment working, generated project with all the default settings for this board. According to STM32F769i docs user LED1 and 2 are hooked up to port J, pin...
I have an old project already using PA 0,1,2,3,5,7 and PC 1,2,3 as analogue inputs, all on ADC 1 and 2. Due the nature of the project I read some of them in a interrupt timer, and some on demand,when a UART command kicks in. I had to add 3 more ADC's...
On the Nucleo-H743ZI board, I'm trying to configure TIM3 with a 10 us period. With the internal clock source at 200MHz, I would expect these parameters to create a 10 us TIM3 interrupt:htim3.Instance = TIM3; htim3.Init.Prescaler = 200; htim3.Init...
