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...
