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 December 01, 2015 at 16:24Hi,I have an stm32F746 configured to run @ 216-MHz. My primary memory is an sdram configured on the block 2 (address 0xD0000000).My memory tests (running from the flash) are all OK (many different tests under diff...
Posted on May 08, 2016 at 05:21Hi all,I have seen a code where a GPIO pin is configured as output in push-pull mode but the pin is driven by an external circuit to low some times (essentially shorting the top transistor to GND). Is it safe to implem...
Posted on May 01, 2016 at 23:19Hi, I experiment a strange behaviour while saving some data in flash: Some interrupts are not fired as they are when not flashing. Timer11 is ''nearly ok'', tick is not, uart reception is not. The joined logic analyzer...
Posted on May 06, 2016 at 07:45HelloWe are experiencing a problem in the power consumption of the STM32F407.Upon entry to ''main'' function we enter device into the standby mode as a first thing.At this point we measure power consumption and observe...
Posted on May 04, 2016 at 17:05Hey guys,I'm using Stm32F429ZGT6 on my own PCB and with STM32CubeMX code generator and Ewarm IAR workbench.I have a problem with HardFault_Handler which happens some times,very random.and when I checked the SHCSR regis...
Posted on May 08, 2016 at 00:51I am trying to receive serial data via USART1 in STM32F429 discovery, but something is holding PA10 high so strongly, that MAX3232 cannot drive it down. According to the schematic there should not be any pullup resist...
Posted on May 01, 2016 at 22:06Dear Community,currently I am experimenting with the STM32‘ demo usb stack (COPYRIGHT 2012 STMicroelectronics) to use it as a mass storage device. This works so far. However I wanted also to use the power delivered by ...
Posted on May 06, 2016 at 19:44hiI wanna use the .NET Micro Framework on STM32F429 discovery board. The STM32F429I_Discovery_NETMF_Package\NETMF_Binary_Image contains the NETMF binary image which consists of three hex files that should be loaded us...
Posted on October 25, 2013 at 15:00Hi everyoneI'm trying to put my STM32L1 into sleepmode and wake it up again with an uart interrupt. So I send it to sleep using:PWR_EnterSleepMode(PWR_Regulator_ON,TRUE)which works, but now it does not wake up when...
Posted on May 06, 2016 at 16:14Short question: What is the recommended way to implement a bi-directional data bus on STM32 using the HAL? Longer version: Our code needs to interface to a LCD controller over a 8-bit bi-directional bus. To do this, we...
