I am trying to trigger conversion sequence on the ADC of an STM32H753 using the CC1 output of a timer. My goal is to start a conversion sequence every 25µs. I know that frequency of the CC1 output is correct; I am counting the events with an interrup...
I'm configuring HSI16 clock and I don't have any problem but when I switch to MSI clock at 262.144KHz, the ADC is not working.Datasheet describes that it's possible to configure the ADC from HSI clock or setting the CKMODE (0x01-0x02-0x03) to make it...
I am working on porting Mynewt RTOS on nucleo-l55ze (Cortex-m33) board,and able to build blinky and load.but led will blink only once and observed the issue that is unhandled interrupt/exception generated while context switching between main task to ...
hello, i am working with a stm32f407 discovery and a current sensor acs712 / 20A , the adc of the card hold input from 0 to 3.3v and the sensor presents an output from 0 to 5v so i have added a voltage divider with two resistors of 2.2k and 3.3k, whe...
Hello Community,I am new to ST MCUs.I want to receive multiple bytes of dat over UART. The size of the data can vary. So I want to use USART1_IRQHandler() when data is received by MCU over UART.I am able to get the interrupt correctly, But I can get ...
Hi ;I have worked with STM32F429i to generate square signal with various frequency. The value of frequency can be shown on OLED SSD1306. I configured I2C1 to connect with this display.When I connect just Rotary encoder, i can see the change of freque...
Hello, I am using L031K6 with its boardI am trying to sense multi- adc port. One is ADC 1 channel 3, other one is ADC1 channel 7I open example code of ADC_DMA and overwrite it, for making my MCU sense these ADC channels, CH 3 & CH 7but problem is,...
Hello Everyone,I try to extract MFccColumn from my microphones plug on stm32h7. But when I put my buffer output audio on my function for extracting the mfcc I always get nan or -nan on pOutColBuffer[NUM_MELS]. Does someone have idea? Thanks,Here the ...
According to the datasheet the STM32L431KB has 128kb of memory. I forgot about this fact and in my linker script I added another section after 0x08020000 of 6 KB long. After debugging and testing my code I am sure that I can read/write on flash abov...
Hello,I know that it is possible to cross series two timers to achieve high resolution one. In my case, 32bit resolution is enough. As a result, I would use TIM1 and TIM3 in STM32F030K6T6 to reach desired high resolution frequency generator. Unfortun...
