Hi,Our device sometimes turns on from Standby by itself. The only wakeup sources enabled are a couple of wakeup pins.I saw the device reset (from standby) by itself, and the PINRSTF flags in RCC->CSR was set. The reset pin has 100nF capacitor to Gnd ...
Hello,I have been using STM studio for monitoring run time behavior of a software for STM32F4 and I have noticed that traces of some variables contain abrupt changes to zero value. The zero values are displayed despite the fact that the actual value ...
Added ADC interrupt handlers to my code.But Overrun interrupt will not compile
Posted on June 23, 2017 at 14:04Hi!Currently I'm using lwip + tinymDNS on a stm32f207.The mDNS needs multicast packets. I activated IGMP in the lwip stack and it works.mDNS messages were sent as mutlicast packets.But the one thing that did not work ...
Posted on March 15, 2017 at 02:47I have just started experimenting with ST products. I have a STM32F4 Discovery board. I bought a DP83848 PHY on Ebay and connected it to the Discovery board. I downloaded a hex file from here:[https://community.st.co...
I trying to use STM32H743VI DMA1 to read from SPI2 MISO RXDR in master mode. Allocated memory in the D2 domain at address 0x3000000C for the DMA1 to copy SPI2 RXDR register to, but the resulting data is corrupted. I did not enable any D-cache at leas...
When we setup a new project on the STM32H743 and select I2S, we get the following error. It appears that the macro SPI_FIFO_THRESHOLD_01DATA is not defined. Any help would be much appreciated..\..\..\Drivers\STM32H7xx_HAL_Driver\Src\stm32h7xx_hal_i2...
Hello Every1,Warning! I am a total noob in STM32 coding. following is my objective:I already have a code up and running(without the sleep) that reads the ADC value every 70us. Now i want the microcontroller to sleep every 70us while its waiting for ...
Hi I live in middle east and I am a beginner . I can't find simple learning source and I can't travel to other countries to learn STM32 . Please help me to learn hal driver how to use with example. I use cubemx and datasheet in it.they don't useful ...
