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 August 30, 2011 at 19:42Attempting to reuse the USB library code and the code example for the virtual com port and basically the system (with a few changes) works as expected. However, we have a situation where sometimes when the host cann...
Posted on September 06, 2011 at 20:51HiI have a small problem that I hope you can help me with. My problem I that the I2C communication stops after some time.I have 2 IRQ, one I2C and one timer 3 update with highest priority, TIM3 interrupt with 20k...
Posted on September 07, 2011 at 14:21Hello, In the datasheet I can read, that the STM32L15x has a MPU. But I didn t find anything about it on the RM0038 reference manual. Does anybody know, where the documentation to the MPU can be found ? Is it the...
Posted on September 06, 2011 at 10:03I need to use Ext SRAM in my application.In order to understand how to initialize and use it for read/write, I went through the Data sheet as well created a project from the sample code provided for SRAM under fo...
Posted on September 06, 2011 at 21:27Hi, I just received a new board (new design, just powered) that is using an STM32F102C6 processor. The tools are IAR 6.21 for development and a J-Link-ARM for JTAG. The sample startup code from IAR (which uses ...
Posted on September 06, 2011 at 15:29I just built a board only to discover that the Ride7 + RKit-ARM toolchain does not support the new processors without an expensive support contract.Is there a truly free toolchain that supports the new processors...

Posted on September 02, 2011 at 00:48Yesterday I hooked up my STM32VL Discovery board as the 5V power source for a simple circuit (powering the STM32VL itself from USB). It worked fine. However, today the 5V pin is only supplying about 3V (and the 3...
Posted on August 31, 2011 at 15:16Hi, I am trying to establish communication between STM32F103C8T6 and an ASIC using SPI.The STM32 is the master and the ASIC is the slave. The requirement of the ASIC is that it requires the MOSI line to be high duri...
Posted on September 02, 2011 at 09:34Hello I am using Stm32f107 controller for my spi application to read nor flash but even after using the sample code given in the firmware library i m not able to drive my Spi as for confirmation when i tr...
