Hi! I'm pretty new to STM microcontrollers and I found myself in a strange situation:I want to create a prototype for a project on Nucleo-L011K4 (and later use L081KZ for the PCB version) and I need to run ADC on multiple sensors paralel. But all tut...
Microcontroller low cost for home health care design
Hello,I have a global variable, wich is accessed by multiple ISRs. Can I safely disable and re-enable the interrupts within an ISR using __disable_irq() and __enable_irq()?Or is there a more elegant way of protecting the variable access?best regards,...
hey,i have an STM32L432KBU6 and i want to serial communicate with my chip. I connected the SWCLK, SWDIO and the SWO pin and followed a couple tutorial on youtube but i just cant get the Serial communication done. i just want to open serial monitor li...
When debugging I found that MX_CAN1_Init() is not getting initialized, inside this code HAL_CAN_Init() is blocked by a while loop.That blocking iteration is as follows/* Get tick */ tickstart = HAL_GetTick(); /* Check Sleep mode leave acknowledge */ ...
We have a board with a STM32G071RBT6. The MCU is controlling a mechanical relay that breaks mains voltage (230V). When the relay closes, this causes the MCU to hiccup in rare occasions: either the core locks up and the WDI resets it, or a NMI excepti...
Dear experts,My SanDisk Extreme 32GB V30 MicroSD HC 1 is not recognized by HAL.... SDIO 4 bits .Stay stuck in the SD_Init...Is that SD card not compatible with the standard implemented in HAL and the MCU ? Time is short and I cannot dig in the lower...
Hello.I am using NUCLEO-L010RB.What I want to do is to monitor the trigger with the GPIO pin during stanby mode, the sequence operation of the GPIO pin at the time of triggering, and the output of 16MHz from the MCO.However, in the current configurat...
Hi,When calling the SE_APP_GetActiveFwInfo function in the UserApp the NUCLEO-L476RG resets every time without any warning or error.Maybe it has to do something with my linker configuration? There are no problems during compilation.Linker script:/* *...
