Hi,I want to use input capture mode with high resolution timer(HRTIM) on stm32f334r8 microprocessor. I am sending a pulse signal over the oscilloscope. I use one of the External Event Input pins for this. I want to capture the rising edges of the pul...
Hello,I am having a strage problem with setting up simple input pins on PB3, PB4, PB5, PB6 and PB7 with pullup on a G441 bare metal. I set the bits in the GPIOB_MODER and GPIOB_PUPDR acordingly and also read them back to make sure. They are correct. ...
Hi all,I just generated a new BSP project from the board examples in STM32cubeIDE. I program this file (audio_sample_tdm.bin) into the address as indicated by the readme file. The audio demo works fine. It play the file and a male voice says "Hello m...
Hi, I'm learning how to use timers by following digikey's tutorial : Getting Started with STM32 and Nucleo Part 6: Timers and Timer Interrupts | Digi-Key Electronics - YouTubeHowever at 9:41 in the video I don't understand the code : // If enough tim...
Hello,I was working on a project and came across a rather strange behaviour with a triggered slave timer. I have recreated the behaviour in a separate isolated CubeIDE project as not to distract you with the irrelevant parts. So, forgive the contrive...
Hello alli have a board with STM32H743BIT6 on it with 4 INTERNAL ADC pin connected to resistor ladders.i connected external 2.5V reference and defined in the IOC file to use external reference.i have constant offset of +150mV and all readings of the ...
Hello,I took over working code that I have for a DSP project from an STM32F439 to an STM32H743. On the F4 I had the external audio codec connected to the I2S peripheral but switched over to the SAI on the H7. Now I am experiencing excessive noise whe...
The CC1125 is a TI sub-GHz transceiver: https://www.ti.com/product/CC1125The User's Guide - https://www.ti.com/lit/pdf/swru295 - says that, after asserting CS, the SPI Master must wait for the CC1125 to pull MISO low before starting the transfer:I th...
