Hi,i'm using a STM32L031. In my code i first initialize the MCU (FLASH, CLOCK, INTERRUPTs, GPIOs), start the LPTIM (running on LSI), then slow down the MSI clock, start the timer22 for PWM and go into low-power sleep mode. When i let the program run...
Hey all,I am using a B-L072Z-WLAN1 that talks to another of the same board using LoRa peer-to-peer. The board I am having issues with is supposed to receive how many pulses to send from the other board, then send them using pwm one-shot mode to PA0. ...
Can anyone help me find the Peripheral Bus to enable Clock for the GPIO Port on the STM32L073RZT6 microcontroller? Please find the screenshot attached.
Hello everyone, I have a stm32l072 microcontroller and an NB exs82 module connected via LPUART. And I'm trying to read a new .HEX firmware that is stored in the NB module's FFS and then make the microcontroller receive the packages that contain the r...
I know this might be a pretty basic thing to have issues with, but after banging my head against the wall on this for days, your snark-free assistance would be greatly appreciated.I am using a B-L072Z-LRWAN1 and trying to get timer 2 channel 1 to pro...
Posted on December 13, 2017 at 17:32 In Cortex-M3, M4, etc, we can just check the DEBUGEN bit in DHCSR (the Debug Halting Control and Status Register) http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0337e/CEGCJAHJ.htmlBut in Cortex-M...
Hi everyone,I'm currently working on developing a bootloader for the STM32L071 microcontroller and could use some guidance. I've outlined the basic structure of the bootloader code, but I'm looking for insights and best practices from those who have ...
Hi, We are using STM32L010C6 Microcontroller, we need to recive the a fixed size of strings (10 charecters ) using interrupted method. But we are not able to receive the charecters completely and its get stuck on the cpltcallback function also. What ...
The micro STM32L072kz supports the OTA (Over-The-Air) method, I would like to perform the bootloader through the main firmware, without the need to use a USB cable or bus, write a firmware that with the help of a 4G modem downloads a new firmware fro...
Hello,After setting up a 4 channel read with DMA, I ran into the problem, that the value of the internal temperature sensor seemed to not change at all. The values of the read out potentiometer however were plausible.So I wanted to check all used cha...
