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...
I have tried everything I can think of to set PB8 high. This is a custom PCB where PB8 is connected through a 1k resistor to a stepper driver input. With board off, measuring pin to VCC resistance is 105kOhm, measured to GND is 95kOhm, so not directl...
On other processors sometimes there are keywords when defining variables to specify which memory area the variable should be stored in. Or there is a #pragma statement. I have not seen either in the STM32 or the IDE. I am guessing RAM2 might be a goo...
I have tried a lot of different things but I can never seem to get it, I am trying to make a semblance of a precise delay function for my controller, I am not using HAL or anything, just writing to registers directly. I tried timers, timer interrupts...
Hi,using CubeIDE with CubeMX, is is possible to "check" or "detect", for conditional compiling, which UART ports that are enabled? In the MX-generated USART.C you will find all the handles for the available UARTs but AFAIK, you can't conditional comp...
Been looking closely at RM figures 342 AND 343.....I cannot see the value of the ARPE bit....when 1 it looks like the shadow register updates on UEV / or Interrupt and when 0 what?? 342 disregards showing the shadow register and on top of this who ca...
Hello,I am working on STM32h745 controller. I am using the DMA for SPI configuration. I declare the buffer in the RAM2 , transmission is done properly but I did not receiving the data on MISO why?/* MODIFICATION STARTS HERE */ .buffer(NOLOAD) : { . ...
MCU: STM32L071cz Application : MDK-ARM essentials version 5.35 when I try to build large project. The "Build Output" window freezes at a random point in the build. uVision is still responsive but I can't stop the build or quit uVision. The only way o...
UNEXPECTED ID code?, the discovery board is original.the onboard stlink is updated to latest version.If i google this Error, i get people trying to flash ST clone mcus, but mine is original. This is my openocd.cfg file:source [find interface/stlink.c...
I have a custom board with an STM32H7A3ZIT6Q. It has the MT25TL256 NOR flash connected to the pins of OCTOSPI1.I'm trying to write a flashloader/driver.In our application we do not need to execute code from this flash. We only need it for data. But i...
