I'm using STM32F429 and trying to use HAL library to communicate to SPI slave via DMA channel. I'd like to ask how is resolved problem with for example sending data to SPI via DMA? Is there any kind of synchronization between SPI and DMA to disallow...
Hello,is there any way to achieve this timer OPM behavior?Arm timer ->Output is inactiveStart timer-> Output gets avtiveCompare register triggers -> Output gets inactiveARR triggers: Timer stops _and_ Output stays inactiveAt the moment, I force the O...
Hi,I'm using the STM32F091 microcontroller on a custom made PCB, i'm reading two switch buttons, both have the following configuration (image below), the SENS_P signal go directly to PA10 of the microcontroller which is configured with EXTI triggered...
Hello all,I am using the h743i eval board and trying to store a large array on the sdram.The problem I am running into is no matter what address I write to, when I read back a value I receive the last value written. I think this may be an issue with ...
Hi,I was wondering if someone can point me to a link where I can download the firmware detailed in the application Note: AN3322Watt-hour meter based on the STM32F101 microcontrollerThanks in advance.
Hello GuysI am building a very simple application using CubeMX. I am using two STM32F207ZG boards to communicate with each other over SPI bus without DMA or interrupts.One is acting as a master another as as slave. The slave settings are as follows. ...
Hi,I try to write a interrupt function with registers on the stm32h743zi referans manual ,but keil doesn't recognize some registers for exp ,EXTI->CPUPR1 =(1<<13); SYSCFG->EXTICR4= (1<<5);stm32cubeh7 MCU package V1.5
Dear ST community,We are running a CAN network with a lot of nodes (>200) using the STM32F107VCTx chip (and MCP2551 transciever) all receiving instructions from a central linux embedded computer with a MCP2515 CAN Controller.Sometimes the nodes stop ...
I am working with STM32F407VG microcontroller (STM32F4 discovery board). When using the DAC peripheral for an application I was verifying the minimum and maximum voltage that can be generated from the DAC pin by providing values of 0 and 4095. Howeve...
