Posted on April 23, 2013 at 15:33 Hello everybody, I would like to know if you have already use IELFTOOL to calculate the checksum of your code and to store it in the FLASH. Like explain by IAR and theirs technicals notes, ->I h...
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...
