Posted on April 09, 2013 at 17:29I configured a SPI transfer with DMA. It's working.Now I would like to add a CRC16 at the end of the frame. I enable the CRC clock and I set the CRCEN bit.The CRC16 is send via SPI link. But I can't check if the CRC ...
Posted on February 27, 2013 at 09:43Hi,in the AN PM0042 I found that the read protection is activated by setting the RDP option byte.It is critical to me that the code is safe 100%. My question is: does this option byte ensure that my code will be p...
Posted on February 05, 2013 at 07:25Hi Eveyone. I'm newbie to this forum and I would expect a single response for this post. Actually i want to encrypt the data that is come from LCD Ram. The dats size would be 37kb when i pass this to fo...
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...
