Resolved! while reading the rtc not providing proper date after the RTC date & time set. how to fix it?
in stm32f407vgt, i declared the RTC structures and set the RTC with date: 1,1,70 and time: 0:0:0 later i set RTC with new values (date: 4,3,22 and time: 10:55:28)after few minutes if i read the RTC it giving a time properly but date is wrong (i,e. 1,...
Resolved! STM32G0 MCU as I2C Master and Slave on the same peripheral
Is it possible to use the same I2C peripheral to be used as both a master and a slave?I made use of an STM32G0 MCU and using examples from CubeMX, I got the peripheral I2C2 to work as a slave and a master separately where I am using interrupts for th...
how to count cpu cycles on M0+ chips?
Hi everyone,I am preparing a course for university and I plan to use G071RB NUCLEO board. I wish to show floating point calculation without FPU is pretty slow, so is there a way to show cpu cycle count feature from debug?Thank you!
How to measure STM32L452 internal temperature using HAL and DMA?
Is there a step-by-step example anywhere, known to work? I have followed numerous examples from several forums, but still no luck. The ADC value I get from the internal temperature sensor is always around 880. This equates to around 1 degree celcius ...
Resolved! STM32F4 chip select problem
Hello,I am having problems with SPI connectivity. My problem seems to be the chip select pin that is controlled using GPIO HAL libraries. Chip select is pulled low for way longer than it is supposed to and therefore I cannot read the sent data proper...
Question about power control on STM32L476 Nucleo-64
Really new to programming these boards, and part of my project is to turn on/off these DC fans . I don't want to add any hardware to incorporate a switch, and was wondering if there was a way to program one of the power pins to be enabled or disabled...
Resolved! How to use DSP in STM32G070?
I have used DSP in STM32F411 successfully,but when i want to use DSP in STM32G070 , i find the DSP files are some different,such as G070's DSP files : ./Sourse/. have a Cmakelists.txt. i dont know how to use that txt file, so i just add DSP as usual...
STM32 CAN Bus not receiving messages, works in Loopback, transmits in Normal
Hello,I am trying to get the CAN Bus on a Nucleo F446RE to receive messages from an ECU, but it will not. The STM32 has been tested in loopback mode and is able to trigger the interrupt and process the data upon receiving the message, and the STM32 i...
STM32L496RGT6 Reducing core frequency while running same baud rate on CANBUS
Hello,In my project I need to get very low power usage device. It works with camera, so when I am taking picture I need maximum processor speed since I need to be at least 4x so DCMI could support full speed parallel data.When I am done with my calcu...
