Re: possible to direct access RNG registers of 32F411 via arduino-ide?

Thank you everyone for your input, I received my 32F407VG board over the holiday and was able to get some results. I wrote a simple sketch to output a random number to the serial port once a second, the RNG hardware is not using interrupt so the crypto quality isn't as high as it could be, but the f...

Re: possible to direct access RNG registers of 32F411 via arduino-ide?

Everyone, thank you for your input. I've got egg on my face and I'm embarrassed that I was trying to use a core that doesn't support RNG. I'm sorry I quoted the 32F411 as having an RNG, not sure what I was thinking. I've amazon'ed a 32F407 to experiment with and I'll report back once I've made progr...

possible to direct access RNG registers of 32F411 via arduino-ide?

Hello, I'm using a Nucleo-64 (STM32F411) and the arduino-ide. The 32F411 datasheet says it has a RNG, and the ST RM0090 datasheet (pages 767-771) clearly explain how the RNG works. From a bitwise perspective setting up the registers, monitoring, and retrieving the random number seems straight forwar...
