Hi,I want a GPIO pin to trigger an SPI transfer. The way that I have figured this should work is:PG3 -> TIM23 -> DMA2 -> SPI1 Here is basically what I have so far:/* Includes ---------------------------------------------------------------------------...
English language:STM32H7 Ethernet + DMA + Cache Explained + LwIP (EN) One of the most common sources of confusion when working with STM32H7 microcontrollers and Ethernet (via LwIP + HAL ETH) is data cache (D-Cache) behavior.When using DMA (like Ether...
Hi currently i am using STM32H735G-DK i need to implement Azure IOT using ThreadX 1. From CubeMX i have generated Drivers for MQTT,DNS,Cloud,DHCP,mdns,sntp in the cloud files where i can update my connection strings of my cloud Configured Asset I ...
Hi , This is the first time I am using USB on STM32F401CCU6 blackpill.I am thinking of developing stereo microphone.To start with I am USING STM32CUBEIDE for development .Selected the STM32F401CCU6 in MCU and have configured the clock to 84Mhz.In Com...
Hello. STM32H5I'm used to cache operations using memory barriers (ISB/DSB), but looking at a function like HAL_ICACHE_Invalidate() or HAL_DCACHE_Invalidate() I can't find any. Are memory barriers not needed with STM32 ICACHE/DCACHE?
It has worked at times but at others is becoming all 0xFFFF or whatever values become written into unused areas.Currently it loses memory every time.My code reads a block of settings and looks at one location to check if it's zero, which indicates no...
Hello every one .this is my first post so excuse me if i do something wrong.I try to establish Uart Asynchronous line between two stm32f303k8 .one of them use basic timer to send 8 byte uint buffer every 200 mili-sec and the other use HAL_UART_Receiv...
Hi,when building the Doxygen documentation locally, numerous warnings appear. Especially, errors like this:stm32g4xx_hal_driver/Inc/stm32g4xx_ll_lptim.h:605: warning: Found unknown command '@rmtoll' stm32g4xx_hal_driver/Inc/stm32g4xx_ll_lptim.h:601: ...
I am looking at the definition ST gives for each of the Xfer options, but so far none of them really are making sense to me. First off, what is Sequential usage vs non-sequential usage and how does this apply for the following:I2C_FIRST_AND_LAST_FRAM...
Hi everyone, I am trying to use the m5 stack hall sensor to measure the speed and distance that an athlete is going. I want to attach the hall sensor to the drum of the machine and measure it. I am having some trouble with getting zero values even wh...
