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...
Posted on February 24, 2016 at 16:50Hello!I have a strange problem with the mass storage usb on stm32407ZGt6. Why is it odd ? That's because the same code works on stm32f407ZEt6 just fine. I thought that these cpu's differ only in the amount of flas...
Posted on February 23, 2016 at 17:40Hi i have a doubt about reponse register. The manual says that response register format is 48 bits but the SDIO reponse register is only 32 bits. then what about the remaining 16 bits .may be its sounds stupid but...
