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...
Posted on March 29, 2012 at 21:49Hi all, i'm sorry if this has been discuss before, but from reading posts i'm still some what unclear, thus my post.Right here goes Has anyone implemented reliably SDIO using DMA along with say FatFS file system ? Th...

Posted on April 09, 2012 at 18:46 Is there a proper way to go into low-power sleep? When I try to step through in the debugger (or at least, let the program run and then pause it), the LPSDSR flag never gets set. And when I let the program run wit...
Posted on April 05, 2012 at 18:43My application calls for using an external oscillator (not a crystal) as a clock source. To test this, I have an arbitrary function generator outputting a 50% duty cycle square wave of the expected clock rate. The MC...
Posted on February 12, 2012 at 01:30Hi, I have modified an example project of IAR for STM32L1XX with a new library definition (one file .c and one file .h). In the file .h I have defined a variable that I use in the .c file. The function defined in ...
Posted on April 08, 2012 at 16:18Hello ! I I start working with STM32L151 + Keil + ULINK2 , and met a problem : after some code, likely it was scommand GPIOA->BSRRL=GPIO_BSRR_BS_2;processor stop the debugging, and a can not start a new debu...
Posted on April 07, 2012 at 22:52Hi, I've been trying to write some code, but I'm running into a bus fault. I'm new to programming, especially with regards to microcontrollers/stm32, so I don't really know how to debug efficiently. I'm using Keil uV...
Posted on April 03, 2012 at 20:12Hello at all, I have to mesaure the delay between 2 signals that I have in input to the microcontroller. I saw the example of the PWM input. I supposed to use an OR gate to have both front to the same pin but I think...
Posted on April 04, 2012 at 07:04STE100P how to set PHY address?Hello. Im trying to using an STE100P PHY ethernet chip (with ST32F217 MCU). In the datasheet for STE100P i see an description for bits 7~3 PAD4:0 in PR20- XMC, XCVR Mode control registe...
Posted on April 03, 2012 at 13:44Hello all.I need to quickly learn how to use the Ethernet on the STM32F217 MCU. 1. I need to be able to setup a webpage that is shown with on board measurements. 2. I must also be able to download and upload data/fil...
