Posted on December 28, 2012 at 00:34Hi, We would like to announce that the CyaSSL embedded SSL library now has support for hardware-based cryptography and random number generation offered by the STM32F2. Supported cryptographic algorithms include A...
Posted on December 13, 2012 at 22:31Hi,I am trying to integrate STM32F2 SHA1 support into an existing crypto API that is structured with three main functions:sha_initsha_updatesha_finalIt appears from the STM32F2 SHA1 example code that the HASH proc...
Posted on October 01, 2012 at 15:44Hello Is there any difference between the CRC module at STM32F1 Series and STM32F3 Series.? I saw that there are some new registers active and some new features possible ! #crc #crc #crc
Posted on September 05, 2012 at 22:44I have a situation where the registers appear to be set up correctly, but when I put data into a transmit FIFO, the output on the USB wires is a single byte with a checksum of 0x0000. Put many bytes into the FIFO...
Posted on July 17, 2012 at 16:38Hi, I've implement bootloader IAP with UART. the code run without any problem and I have software upgrade support to my project. I'm using IAR for ARM v6.40.2, I've tried to use the Linker configuration to generate bi...
Posted on April 03, 2012 at 11:57I've interesting behavior on STM32F105VC. I have SPI3(remmaped) master with SPI auto CRC calculation (RXCRC,TXCRC). For 9Mhz it is fine, for 18Mhz I receive all words correct, including CRC, but RXCRC register is wr...
Posted on March 23, 2012 at 19:09 I'm lost with my calculation of crc for 16 bit transmit mode, with a polynom 0x8005, init = 0x0000. I am calculating in Matlab a lookup table first, which seems all right: 0000 8005 800F 000A...
Posted on February 18, 2012 at 21:29Hello guys. I was trying to read the code out of a STM32F105RBT6 using a SWD circuit and the STMprog software but the code was ''Read protected'' and I couldn't bring it out .Can you guys give me a help or suggest...
Posted on February 17, 2012 at 14:46Hi, I'm interested in using the cool STM32F2 devices. Some of them also contains symmetric key cryptographic support. Does this mean that they fall under the Wassenaar Agreement? #crypto
Posted on February 09, 2012 at 21:59Hi everybodyI'm trying to use the encryption libraries with an STM32F4Discovery board.However, the function HASH_SHA1 is not obtaining the hash value, it only got zero.I am using this code to obtain the hash:====...
