The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on January 26, 2015 at 14:48 Hi, It's already a few weeks I'm trying to bring up a solution of the USB Host via USB HS module with internal FS PHY. The same code works fine if I use OTG_FS module, once I pass to OTG_HS I'm starting ...
Posted on March 08, 2015 at 04:10I need to read the flash, add 1 then flash back to same address, so that I can keep track how many time the user use the device, I use: ~~~~~~~~ FLASH_Unlock(); FLASH_ClearFlag(FLASH_FLAG_EOP | FLASH_FLAG_OPERR | ...
Posted on March 06, 2015 at 20:29I'm using Keil on an stm32f4xx with 10ns read/write sramI have configured the FMC with a data ready of 2 HCLK (my speed is 180 Mhz) so that is 90 Mhz, which is slower than the rating of 100 Mhz of the SRAM, however t...
Posted on March 09, 2015 at 10:02Hello, I am using STM32F3 Discovery kit. I need to calculate logarithms and exponential function (e^x). I cant find these functions anywhere. Are they in any libraries from ST? Thank you for answers
