Hi,I am using the relatively new STM32G4(74).I am currently implementing the OPAMP-abstraction and i am having issues with calibration.The calibration works in general, if the output routing goes to the pin (OPAINTOEN = 0). (n&p is around 15/16)The c...
I want to use ADS112U04 to read temperature (by enabling temperature sensor mode) and send this result to STM32F777VI via UART interface. How can I achieve this? I'm new to STM32. I have seen an example which does same with MSP430 microcontrollers, b...
When working in interrupt mode, I can not track all the events.I only seeTOUCH_EVENT_LIFT_UPTOUCH_EVENT_CONTACTmoreover, the TOUCH_EVENT_LIFT_UP event is registered twice,but the TOUCH_EVENT_PRESS_DOWN event is not logged at all.if (TS_State.touchEve...
The ARM-M7 supports non-aligned memory accesss using LDR and STRhttp://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0646a/BABFAIGG.htmlbut it isn't working for me. I'm reading and write to/from DTCMRAM.Is there anything I need to do to get...
Hi everyone,I am trying to run some tests to cahnge our board into the low power "STOP" mode. Currently the entire board draws an average of ~9 mA when in our current low power mode. Though we need to add additional functionality and would like to us...
Hello;With STM32H747, I am trying to communicate with both cores. For example;To be able to read a variable in CM4 in the CM7 core. Depending on the state of this variable I read, running certain functions in CM7, etc.I couldn't find a document or ex...
The maximum allowed internal clock for the device STM32F446RE is 180 MHz. The nucleo board has an external crystal of 8 MHz. Using this and a code I obtained from a university website, I attempted to change the system clock to 180 MHz using the PLL.(...
When I use HAL_NVIC_EnableIRQ(64) from CPU1, it interrupts same core (i.e. CPU1 instead of CPU2).
Hi everyone!I am trying to get the lowest power consumption from the STM32L073ZR in STOP Mode.I run my tests with the board powered from external source E5V (no USB connected).I have two Ampere-meters:one measure the current IDD of the microcontrolle...
Posted on August 03, 2017 at 20:26Hi, recently in a project I need the GPIOs on STM32 to operate on 1.8v logic level. By quickly looking through datasheets, it seems many of STM32 can do so, for example, to STM32F407VG, if provide 1.8v to VDD, it ru...
