Posted on November 16, 2016 at 10:25Hi,Currently I implemented SPI communication to external device using Nucleo-64 stm32f401RE.SPI implementation is based on Bit banding and not the HW SPI.Clk rate is ~3.2MHzSince the Nucleo-64 is used to communica...
Posted on November 12, 2016 at 23:21After I compiled the .lib library file using KEIL tool, then using rm-none-eabi-objdump to parse the .lib or any of the intermediate .o files, GCC objdump reports that ''File format not recognized''. I was wonderi...
Posted on November 16, 2016 at 09:44Hi! I wrote program for STM32F407, where I set PLL as the source of SYSCLK and want to see it on pin MCO1.The program is:#include ''stm32f4xx.h''uint32_t i, temp;int main(){//config clockRCC->CR=RCC_CR_HSION;while...
Posted on November 09, 2016 at 14:57Hello,I'm trying to use the firewall on STM32L486 MCU and I'm faced with a problem.I have a security code with one entry point and a private data that should be protected by firewall.I'm trying to prevent reading ...

Posted on February 18, 2016 at 10:39Hi, I have implemented HID Power Device (Battery as HID) on STM32L0. I need only proper report descriptor and report to send to windows. I have got working report descriptor from , but I can't create proper report...
Posted on November 16, 2016 at 09:20Hi, i am new to STM32 programming. I have to make a small program where the STM32L471 is the SPI master. I tried the CubeMX to build a program for the Keil MDK. Seems to be ok. But when i call the transmit functio...
Posted on November 07, 2016 at 09:09Hi,we use a USB custom class of our own.For STM32 devices we changed the CDC files (of the USB device library) according our requirements. The CDC files were based on the standard peripheral library.This works fin...
Posted on May 28, 2013 at 10:31 Hi guys, I'm in a bit of a crisis to get I2S working with DMA. I want to transfer Data from a TxBuffer array to the SPI3->DR Peripheral My setup is: I2S3 InterfaceDMA Dir Mem2PeripheralDMA ...
Posted on June 04, 2012 at 11:15Hi all, I'm using the STM Discovery EVM to make some sample program. I'm using IAR as compiler and CMSIS 2.1 In this example I simple set a timer with 50ms period and start DMA transfert on USART 3 The transfer is co...
