STM32L4 PWM Phase Delay

Posted on February 19, 2018 at 19:02 Hello: Using the Nucleo STM32L476RG demo board. On an STM32F4xx, using CMSIS, I am able to create 2 PWM pulses that have the same period. However, the 2nd pulse is delayed by: TIM4->CNT = TIM3->CNT + (timerP...

what's address of VREFINT_CAL in STM32F103?

Posted on March 01, 2018 at 02:15I can not find it in datasheet in 'Embedded reference voltage' section.I also try use STM32F0/STM32F405/STM32L486 address. all these address are wrong.#vrefint_cal #stm32f1 #internal-reference-voltage-calibration-val...

Reliably detecting power-off/on with stm32l432

Posted on February 28, 2018 at 16:24The stm32l432 lacks the PORRSTF flag that other stm32 processors have, so I don't see a way to reliably detect a power-off/on event.  I tried parking a bit in the backup registers, but it doesn't appear that this ...
