Timer during StopMode

Is it possible to set start a timer (e.g in a function), then enable the StopMode in the whileloop, and when the timer has expired wake up agian?

I am trying to interface TM12864H6CCGWA-1 via SPI on nucleo-L073RZ .I am unable to print anything on display. I have checked all connections , all pins are connected correctly but Its not working. Please help me.

Measuring LIPO battery voltage on ADC pin.

What can be the range of output voltage i can set at output of voltage divider.External impedance mention in datasheet is 50kohm. How can i match same impedance at the input of ADC pin while using voltage divider?There are various values of RAIN ment...

Pin of OSC32_IN, OSC32_OUT and the best shield should be

Dear all,I am using STM32F103RBT6. I am wondering if I can leave folating the Pin for OSC32_IN/OUT because I didn't need them for my application.I want also know, how can I do the shield of the MCU STM32?Best regardsHafedh

STM32L1 cant enter lowpower sleep

Posted on July 26, 2017 at 17:59 Hello everybody. I simply can not figure out the settings needed for lowpower sleep. I am aware of fact, that i need to enter lowpower run first. My setup: - MSI 1048KHz - PWR Reg Voltage Scale Scale 2 ...

STM32F0 SPI TxFIFO Flush

Posted on November 10, 2017 at 20:05Hi,i've found simple problem with Tx FIFO in SPI in slave mode. Take a model situation from reference manual (STM32F031) 'Figure 281. Slave full-duplex communication'. Imagine situation when master stops communica...

How can i test Low power current consumption on Nucleo-4R5ZI development kit?

Please suggest code and setup to test all low power modes supported by the STM32L4 controller series and Nucleo-4R5ZI development kit

stm32f401 footprints/pinout are they all identical?

Hi All,I downloaded the stm32f4 footprints library for altium and could not find a footprint for STM32F401RET6 (LQFP64), but in the library I can only find STM32F401XB and STM32F401XC footprints. However these chips only provides 256 kb of flash memo...
