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 February 17, 2015 at 15:54Hi all! I'm a bit confused by USB Host behaviour when trying to enable Suspend mode.I use ST USB library v.2.1.0. and STM32F407. Use Host example for HID device, and it is working correct. Now I try to make some c...
Posted on July 20, 2015 at 23:30I'm trying to interface a push button to my stm32F4 discovery via PA1 , this is the code I got : void EXTI1_IRQHandler(void) { if(EXTI_GetITStatus(EXTI_Line1) != RESET) { EXTI_ClearITPendingBit(EXTI_Line1); ...

Posted on July 21, 2015 at 05:36Hello Is there any tutorial for Discovery Stm32L152C to use SD cards?
Posted on July 20, 2015 at 10:02Hi Guys,I'm struggling to activate the can bus in the CAN2 module in the discovery eval board.Using CubeMx, Generated all the initialization code.Set baud-rate to 50KHz, and to loop-back mode.The output waveform looks...
Posted on July 20, 2015 at 21:54Hi there , I had my STM32F407VG discovery board for a while now, till a few minutes earlier, I was trying to interface a button to PA13 ( I chose PA13 randomaly) to create a simple interaface for my project , but once...
Posted on July 20, 2015 at 21:53Does the new STM32F7 series omit bit-banding support?There is no mention of bit-banding in the STM32F7 reference manual. Attempting to use bit-banding results in a fault condition.I'm surprised by this omission. Or ...
Posted on July 20, 2015 at 21:42I write some code that seems to successfully put the chip into standby mode: PWR->CR |= PWR_CR_PDDS; SCB->SCR |= SCB_SCR_SLEEPDEEP; while (1) { __asm(''WFI'')__; }That seems to stop everything as expected. Wh...
Posted on July 20, 2015 at 19:47Hi.I'm looking for some help with the STM32F072.Q: What are you trying to do?A: I'm trying to read the factory measured voltage of the bandgap voltage reference in order to calculate the VDD as exactly as possible. As...
