Posted on April 28, 2017 at 10:40I have two STM32F103 connected together with SPI in full duplex mode. They changing 700 halword with DMA and CRC enabled. The communication is fine (no crc or other error) but there is this line of code in the SPI_DM...
Posted on April 22, 2016 at 12:31Hi,I need to implement an existing circa algorithm [1]. I have a table driven C implementation, but I would like to use the STM32L4 CRC peripheral. I�ve read the chapter in the reference manual, and I know which para...
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...
