I am using STM32L431RBT6 consuming 2.63mA of current. How can I further reduce the current consumption ?. I am using MSI at 8 Mhz , and peripherals used are SPI1, SPI2, UART and I2C.
Resolved! Sending data to SPI via DMA
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...
STM32 Timer OPM question
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...
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
