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 January 02, 2012 at 15:52Is it possible to make software reset of procesor , and tell him to execute from RAM (without pooling BOOTx pins ) ? I want to remove RDP bit and I need to reset procesor and next execute it from procedure loaded t...
Posted on December 13, 2011 at 17:31 Hi all I try to success a connection between PC and SMT32VL-Discovery Board via USART. The Data receive but are not correct. I tryed everything, but the data i receive onPC are still wrong. Ha...

Posted on December 19, 2011 at 00:07Hello. I have problem with upgrading program in my own bootloader. When procesor is not read-out protected, everything is going ok (verify says ok). Problem occurs when I set <Read-Out Protection> in RFlasher7 (u...
Posted on December 29, 2011 at 21:37I have a MCBSTM32 board which uses the STM32F107 and includes a CS42L52 audio CODEC chip on board. I'm trying to create a 12 MHz clock input for the CODEC using TIM3 from the STM32. So far I have succeeded in gene...
Posted on December 16, 2011 at 13:12Hi all, I am trying to program the discovery board of stm32f4 using SWD via the Cn3 connector. Does anyone have any experience in that.. Arun
Posted on December 30, 2011 at 11:26Hi all, I have STM32L-Discovery and STM32F4-Discovery boards. When they're already flashed and connected to target device, ST-LINK chip still work, consumes power and blinks LEDs. Is there any ideas how to swich ...
Posted on November 16, 2011 at 15:11Hello, I try the examples about PWM input form st.com, but it works only for big frequency signals. (like it is said in readme.txt). What should I change with settings TIM4 for example, to be able to check the low...

Posted on December 27, 2011 at 08:50I'm debugging on an Olimex STM32-P103. I think I have the PLL set up at 8 times the 8Mhz crystal. If so, then instruction timing is pretty poor. Here's my loop:ldr r0, =portcldr r0, [r0]mov r1, #0x80mov r2, #0lo...
