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 am trying to write a code using STM32f103r8t6, i have installed IAR for Arm v8.40.1 i started to create a project but i could not find any library files. and then by downloading an example file i got the library files as i tried to complile i m ...
I detected that ART accelerator and prefetch is not enabled. Why for loop gets slower if if I switch both on ? /* USER CODE BEGIN SysInit */ #if defined(FLASH_ART_ON) // enable ART for Flash (x8 Booster) int FLASH_ACR_REG=0; volatile unsign...
Hi!I have a basic code - blinking LED code which uses onboard LED (PC13). The problem is that it doesn't toggle at all, it just stay switched on and doesn't go off after delay. I've tested that code in debug mode and everything worked fine, it toggl...
CPU 210MHzIf you run IRQ code from flash you have about 5 times more cpu cycles as needed (7WS)if you switch on ART accelerater and prefetch: for loop gets slower no influence on IRQ latencyyou could not run code from internal SRAM because of missin...
Hi folks, I have tried to run my complete program out of internal SRAM to speed up the IRQsbut if I come to svc 0 it failsprvPortStartFirstTask: 20005ee0: ldr r0, [pc, #32] ; (0x20005f04) 20005ee2: ldr r0, [r0, #0] 20005ee4: ldr r...
We are using STM32F765IIK6 176 pin 10x10 0.6mm UFBGA, die rev "Z". Whilst processing these through SMT solder reflow (using an 8 zone forced air convection oven) we had a number of these devices failing, due to the substrate of the BGA package dishin...
Hi,Does anyone know if there are any companies out there that sell production ready stm32 hardware boards. I appreciated there would be a lot of variations regarding io etc.. but i just wondered if it was a "thing" or if the only board are typically ...
Hi,I am currently working on an STM32L4S5 attached to a ST-LINK/V2. I am using Attolic TrueStudio to compile, flash and debug.The STM32 is running at 120Mhz and I have configured the SWO clock to 125kHz thanks to the STlink utility software.I am usin...
Hello!I am just getting started with STM32 universe. I've already finished my first project using the IDE SW4STM32 and I board I've designed using the STM32F070CBT. I've also used STM32CubeMX to generate the basic code.I wanted to keep using this boa...
I'm trying to enter STOP2 mode to save energy but the MCU get stuck in the function HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI). I have cleared all EXTI pending flags and RTC flags, and disable all five wake up pins. The MCU is supposed to wake up vi...
