Hi I have setup the RTC on the STM32L433 and the clock is running about 5 second fast in 24 hours. I am using a 32.768KHz crystal, which is directly next to the processor . I have set the RTC->PREDIV_A to 0x 7f, and RTC->PREDIV_A to 0x ff, and selec...
Hi - I am fairly new to RTC and Watchdog Timers, so my apologies in advance if the questions seems trivial =) There seems to be some concerns that when used in conjunction with Particle Boron MCU's, simply resetting the MCU will not suffice but Power...
Running STM32CubeIDE 1.5.1 with Nucleo-stm32L433RC trying to get LPTIM1 to work consistently. In Selective03.png I show the initialization of the LPTIM1 (LPTIM_PERIOD is 32767 and LPTIM_PULSE is 16383). So I expect CompareMatchCallback() to happen...
i want to use a board as master and slave simultaneously. role= GAP_PERIPHERAL_ROLE | GAP_CENTRAL_ROLE; now, i am able to establish a connection between a Master&Slave board and a slave board. however, when i want to set the Master&Slave board into ...
I'm trying to setup single-pin, unpiolar PWM Generation outputs on Timers 8, 16 and 17 of my STM32 MCU (STM32F303RBTx). I am using the latest version of STM32CubeMX and the STM32CubeF3 firmware package as of today (Dec 18th 2020) to generate the appr...
Solution: Just like TDK said, PC13 pin is active high (can be seen below).Original q:Hello everyone,I and a few other friends of mine all ordered Nucleo 64-F103RB board, it comes with 32F103RBTx MCU. We did worked before ST MCU's (like 4-DISCO boards...
Can someone shed light on what I am seeing?I was trying to validate the set up of one counter using the ISR of another counter. While the program was running I placed a break point in the code to stop and read the values. The difference values read f...
Hi, I tried to do a research but since I'm kinda lost and nothing helped me to clear it I decided to ask here. I got STM32H747i-Disco + MB1280 A-03 (to receive CAN). I designed graphics in TouchGFX, which should act accordingly to CAN messages rece...
Current scheme involves trying to fence the current count by knowing the direction with CMP to trigger at the next position. Direction-change interrupts to alter which side CMP is placed with ARR match to handle the starting case where we don't real...
In my design i have 5 gpio that connecting my keypad , i have 3 row (gpio output ) an 2 col how input , one button keypad is ON/OFF.For me the OFF state corrrespond to sleep state .This is my problem -Before of while i enter i sleep mode :void PW...
