I have a project that involves a STM32F7 controlling a stepper motor through GPIO. I have now been tasked with redesigning it with a ST L6470, a motor control IC which has a SPI interface. I would like have a shared codebase so that a simple #define ...
Hi,How can I power cycle the Nucleo-144 between debug sessions with out unplugging and reinserting the USB cable. Is there a way to toggle PWR_ENn on the STLINK using openOCD and if so could someone please post the script that does this?thank you
My MPU is STM32L152RET6I am using i2c channel 1 to communicate with an i2c device. I used the standard device set and verified the hardware appears to be set up correctly. When I set the "Start" bi in control register 1 (CR1), a start condition is g...
I am currenctly working on STM32L052K6T6. I would like to know if there is an appropriate way to measure precisely the voltage used by the adc. I read through the documentation that this voltage was on adc_channel17 but i have no idea of to get it. I...
Hello,I am trying to switch on pwm for 10 ms timer and then switch off pwm and use those pins as gpio (high and low) also for 10 ms. This whole process will work in loop.We even tried to set idle state of pins as set and reset in cubemx but as we sto...

Using:STM32L4SVITDBANK=1The reference manual seems to state that a Mass Erase must be performed before every FSTPG. However the requirement is not clear. Assuming it is correct that a Mass Erase is required to use FSTPG: 1.Is there a time window ...
