Hi, i find myself wanting to use stm bootloader instead of having to code my own.:| My setup consists in 4 identical nodes hooked up to a 2m long canbus.I can boot and talk with the canbus bootloader only when a single node is powered on in the bus.(...
I tried generating PWM on my stm32g070rb but when I connected my PA7 and GND to my oscilloscope, the output I got does not look like a pwm signal in any way, I have verified my connections and now I think the error is from my code.
Hi ST Team, Currently i am using STM32F105RBT6 in our project. In this project i am using microcontroller internal RTC module to monitor the time with LSE clock for RTC run. When the LSE crystal(32.768) is not mounted in our PCB th...
We have a project running on the STM32F411 via the standard discovery board :https://www.st.com/en/evaluation-tools/32f411ediscovery.htmlIt has been verified that with the STLink port plugged in the BOOT0 pin is at GND and the NRST pin is at 3V. We ...
I acquired some code for an STM32F3 that performs LIN communication over USART1. Previously the code used DMA channels for both memory-to-peripheral and peripheral-to-memory transfers to/from USART1, but it had some problems that required restructur...
I am trying to create a voltage divider to read a battery voltage of 2.5 - 3.8 V using a STM32L082KZ with a Vref of 1.8V. While calculating the required division to measure the range i wanted to include the influence the ADC measurement/loading has o...
The datasheet says that power must be supplied on this pin if USB is to be used. It must also be the last power supply to be energized and the first to be removed.If my design does *not* use USB. Can I tie this pin to VSS and call it a day?I want to ...
I have an STM32-L4P5DK connected to an external ADC, with SPI2 configured to read ADC samples on every falling edge of the DRDY signal. The DMA1 configuration is as follows:DMA1 CHANNEL1: DMA_GENERATOR0DMA1 CHANNEL2: SPI2_TXDMA1 CHANNEL3: SPI2_RXThe...
Hi Everyone, I have a project utilizing a STM32G030F6P6 with a 32.768kHz crystal and the LSE to source the RTC clock. It is exhibiting 2% clock error (which is huge!) over a 10 minute period despite using a 20ppm crystal. I am measuring this error by...
I need to generate a pulse which is activated high immediately by rising/falling input signal around 100Hz with varied width. I have tried One Pulse Mode and Gated Mode on STM32f334R8T6 so far but none of them were successful. Even I tried on HRTIM,...
