How to establish UART communication between two microcontrollers
I am trying to transfer sensor data collected on a NUCLEO-144 L552ZET6Q board to a Sparkfun Artemis BLE Module via UART DMA. However, I can't get the STM32 to send anything on any UART besides messages to TeraTerm using the basic HAL_UART_TRANSMIT fu...
Resolved! What could be the cause of a constant voltage offset on the STM32L041G6 ADC?
I have been testing the ADC on my STM32L0 with 12-bit resolution and for some reason, every measurement I take has a 0.048 V offset. I've tried a different supply voltage (from 1.8 V to 3.3 V), but the offset stays there.This offset starts at the fir...
Resolved! Correct order of using HAL_ADC_RegisterCallback function
Dear ST Community,as part of a project to capture analog microphone data, I would like to use my own callback funtions instead of hal callbacks. For this I register my ADC callbacks with the HAL function HAL_ADC_RegisterCallback as follows:/*********...
Try to filter some bits in CAN id of STM32F746NG, in 32bits configuration, extended id, mask mode
Found the answer.Can be deleted.
STM32H7 timer interrupt slightly too fast
I am using TIM2 on a STM32H7 to generate interrupts - e.g. every 1 ms. Using the formulas from the documentation, Update_event = TIM_CLK/((PSC + 1)*(ARR + 1)*(RCR + 1)), solving for ARR and using RCR = 0 we getARR = 1/(Update_event * (1 + PSC) / TIM_...
RTC hours keep counting after 24 hours
Hi,I use RTC on a STM32L073. Every 12hours, I receive a date and time to set to the RTC. (Sometime, like 1% of the time) After writen the new RTC value, the RTC doesn't overflow after 23h59min59sec and keep counting without incrementing day. I can ha...
Resolved! STM32H7 Power down sequence
About Power-Down Sequence (Device : STM32H7B0xB)Datasheet : DS13196 - Rev 6 Page 13"During the power-down phase, VDD can temporarily become lower than other supplies only if the energy provided to the microcontroller remains below 1 mJ. " Could y...
Multi channel ADC + SPI + I2C
I'm using STM32 NUCLEOH743ZI2 board were I have written a code which consist of Multi channel ADC using DMA with timer, SPI and I2C protocols. SPI and I2C is not working whenever multi channel ADC is enabled else SPI and I2C is working fine. We are u...
Resolved! F411 System Clock Configuration with Internal Clock
I have been working F411RE Nucleo board with LL library for quite some time. I found the sample code for SystemClock_Config uses external oscillator as showed below. I wonder if there is any sample for internal oscillator. /* Enable HSE oscillator *...
