Posted on February 25, 2016 at 10:28Hello everybody and thanks for your help.I have been reading a document called: UM1724 STM32 Nucleo 64 boards User Manual and although very useful (more than other documents) it still left me a little confused so ...
Posted on February 25, 2016 at 11:27Hello,I need advice about AES 128 or AES 256 implementation in STM32L0 series. What is the best solution? Do I have to use the controller with AES hardware accelerator or there is a software solution that is fast ...
Posted on February 25, 2016 at 09:14I am trying to live upgrade the firmware i.e. download firmware in bank 2 of flash memory while bank 1 is still executing the code and vice versa. I need to give starting address of flash memory where the new firm...
Posted on February 25, 2016 at 09:22Hello everyone, i have a circuit where 8 I/O (5V tolarant)pins of my STM32F407(supply is 3.3V) are configured as inputs and are tied to 5V with a 10K pull-up resistor. The I/O as inputs work ok but when a configur...
Posted on February 17, 2016 at 01:15Hello and thanks alwaysI am programming a STM32 Nucleo with mbed and I have a curious situation. If it sounds familiar to you, I would appreciate any pointer, advice or commentI have successfully programmed the nu...
Posted on February 24, 2016 at 15:21Hi,I am using stm32f103vb discovery board. Here i want to access UART1 and UART2 simultaneously. I have done coding in which i am able to transmit and receive data either through UART1 or UART2. But not able to en...
Posted on February 25, 2016 at 04:43Dear all, I have made a board with STM32F105RCT6 to suit my requirements. I want to use the USB as device (Virtual ComPort). I downloaded the USB libraries from ST, where there is a mention of 105 libraries being ...
Posted on February 16, 2016 at 10:36I have a board that has an STM32F405 with the USB pins routed to the USB connector. I had problems getting that board to boot, and I was unable to get it to work as DFU device on USB. One of the possible causes is...
Posted on February 16, 2016 at 20:00Hi.I encountered a problem where I use CRC hardware with optimized code in Keil. I use CRC hardware inside of interrupt routine and without optimization I get correct result. But if I turn optimization on (level 1...
