Posted on March 28, 2017 at 12:38 Hi I m using stm32f4 for my project. My project has AES encryption and decryption parts. I using standard peripheral librarys. Standard peripheral library has http://www.hanese.nl/STM32/stm32f4stdlibrary...
Posted on March 02, 2017 at 13:13Hello,I've already written on the forum without luck. I'm in trouble trying to figure out how to verify a message signed using ECDSAsign function. Locally it seems to work, but if I export the signed hash, it is not ...
Posted on January 27, 2017 at 08:25 I am trying to use the hardware peripheral on the STM32F072 to calculate a 16-bit CRC for a modbus RTU application. The hardware peripheral offers twice the speed compared to my software implementation. I am...
Posted on January 19, 2017 at 08:47Hi,I'm developing a customized SPI Bootloader code. I plan to use CRC32 in verifying the programmed application code. I used this link as a reference for my CRC32 calculator C-code function in the Bootloader:https:...
Posted on January 17, 2017 at 10:18Hi , i am new to linux,i am using crypto 3.0 package and stm32F205xx andencounter several problem :i write my own makefile and linker script (mostly copy from guthub)I use stlink-texane and gdb to debug, here are s...
Posted on January 11, 2017 at 05:32hi i am new to linux,.this is my first time to use command line makefile to compile.i now encounter a problem that undefined reference to `AccHw_RSA_PKCS1v15_Encrypt' in the /Examples_Crypto/Src/example_rsa_encdec....
Posted on January 12, 2017 at 21:10This CRC is used by an I2C peripheral and documented at http://www.sensirion.co.jp/fileadmin/user_upload/customers/sensirion/Dokumente/GasFlow/Sensirion_Gas_Flow_SFM3000_CRC_Checksum.pdf Can this CRC be duplicated...
Posted on December 30, 2016 at 23:26The only off the shelf board i have found with crypto block on it is STM3221G-EVAL, a bit pricey and got tons of features that i dont need.For cheap testing, de-chipping NUCLEO-F207ZG and populating it with STM32...
Posted on December 12, 2016 at 08:26 Hello All, I want to implement MODBUS RTU Slave for my Discovery STM32F0. I have worked on this protocol in 8051 controller. As i was going through CUBE i saw CRC peripheral in STM32F0 so i was curious and ...
Posted on December 19, 2014 at 11:27We would like to enable level 1 read-out protection from code running on an STM32F437. We have code that will enable the protection using the following steps:1. Unlock OPTCR by writing twice to FLAS->OPTKEYR, usin...
