Resolved! STM32F373 ADC internal channels only measure 0xFFF
Hello,I´m working on a Project with a STM32F373CCT. I need to compensate the signal read from the SDADC Signal with the internal ADC Temprature sensor.The Problem is that I only get the Value 0xFFF from the internal Temprature Sensor and also the Ref...
Setting up SPI for AD7190 with STM32G474CE
Hi all, I am trying to setup SPI for the ADC AD7190. I am just attempting to reset the ADC after power up and then read the device ID register to check the communication. I have not been able to do that until now. I will summarize the code here and I...
Resolved! What is a vector table and what information it contained while flashed with a OTA user application?
Hi, I learned that when we flash a binary file to flash, we add the vector table with it. I want to know what is actually is a vector table. I am actually working on uploading a .bin file to flash using IAP. verify it and jump to it. let's say while ...
Is there a way to detect a dead time of 300us using "only" a timer?
Hi,is here a way to toggle a GPIO pin if a timer detects a 300us dead time in a continous/clock signal?If so, how? I would like to use a timer only, so no "individual" coding, just CubeMX configuration.
Hello everyone. I'm using a ADC with DMA. The device is stm32l073.
If the ADC is used alone without using DMA, the data conversion will be performed in the cycle described in the data sheet.However, the conversion time is doubled when using DMA.Do you know why?Common conditions・Clock : 16MHz・Clock Prescaler : Asyn...
Resolved! How to identify which timer channel triggered the "HAL_TIM_PeriodElapsedCallback" interrupt?
I am using STM32F302R8, and have setup channels 1 to 5 of TIMER1 in various output modes. In the callback function, I would like to identify which channel generated the interrupt.I am using HAL, and can figure out which timer generated the interrupt,...
STM32G0 Custom Board NRST floating
Hello everyone ive been using STM32 microcontroller on custom boards for some while now, but particularly with the STM32G071G8 some boards are failing. After a few minutes, NRST seems to flicker and drop from 3V3 to 2,2, 1,7 and finally steady to aro...
Resolved! State of GPIO after Watchdog Reset
Hello, I am using a STM32F401CE and would like to use the independent watchdog to cause a reset if the device would lock up for some reason. I have an external chip which is being controlled via GPIO and SPI from the STM32F401. When a watchdog rese...
Hi Team, I'm using a STM32L4R5 and am wanting to store variables in SRAM2 as static variables so that they hold their value while the micro is in standby mode with SRAM2 retention enabled. What am I missing?
I've followed every tutorial/thread that i've been able to find but cannot get this to work. I've set: RAM2 (xrw) : ORIGIN = 0x20030000, LENGTH = 64Kand .ram2_bss : { . = ALIGN(4); *(.ram2_bss) *(.ram2_bss*) } >RAM2In STM32L4R5ZITX_FLASH.ld and defi...
