EXTI configured to trigger on RISING edges but triggers on both FALLING and RISING edges.
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...
Resolved! SDRAM Read/Write stm32h743
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 ...
Firmware for App Note AN3322
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.
STM32F207 not working as SPI slave when NSS is configured in software mode.
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. ...
EXTI registers
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
Most proper way of detecting CAN BUS OFF condition?
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 ...
DAC peripheral on STM32F407
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...
How to control on board ADC with SPI bus (STM32F051)
I connected a particle photon micro controller to STM32F0 discovery board using SPI bus. The photon acts as the master and STM32 acts as the slave. I understand how to code on the STM32 directly though IDE to use ADC but how to do this by sending da...
