STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
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...
