HII have a problem. I want to measure 4 channels of the ADC every 20 seconds (this is more time but for now it is like this for testing) through an RTC interrupt, then print by the serial terminal.What happens is that it shows me the reading every 20...
Hi,I have a project involving an STM32F030C8T6 MCU. The datasheet says that pin PF0-OSC_IN and PF1-OSC_OUT have I2C1_SDA and I2C1_SCL as their Alternate Functions. When I go CubeMX to select them as such, it doesn't give me an option to do so, even t...
I want to run a Nucleo L476RG at 1.8V at first glance it looks possible with a few caveats.according to the schematic (C03)https://www.st.com/en/evaluation-tools/nucleo-l476rg.html#cad-resourcesThere are two regulators I need to be concerned withU4 w...
Hello. I bought a STM32G474MET6 chip on Alibaba and the supplier claims that the chip is original but I have some doubts. Here are the attached images he sent to me. Can you please check that and confirm if it’s genuine please ?
Hi,MCU - STM32H7I have noticed that the CoreDebug_DEMCR_TRCENA bit in the DEMCR register is set by default if a debugger is connected. But, I need to enable it explicitly (as shown below) if the debugger is not connected. CoreDebug->DEMCR |= CoreD...
Hi all,We deployed a lot of devices that have a STM32G431KBU6 controller.It basically has a foot switch to turn on/off a 12v DC motor and a rotary switch to control the speed.We use EEPROM emulator to save the speed setting.If speed setting is differ...
I have a custom design using the STM32G474RBT3 (128kB flash category 3 device) MCU. In this application, the firmware needs to be updated remotely via the normal communication channels to the board. In this case, it is Modbus over an RS485 multi-dr...
Hello all,I have done my due diligence looking everywhere for an answer to this as well as trying many different variations of the code I will post below. My issue is my LCD will not display the ADC value from a trimpot any other way. I thought at fi...
Hi, I am using MKI109V3 (STM32F401VE) as motherboard and MKI239A as IMU adapter. My Unico version is 9.16. Following UM2116, I tried everything in Windows 10, including firmware upgrade to 3.58.2 (latest), and all data display works fine in Unico.Aft...
Hi all,I'm starting to use GreenPAK devices... I use the SLG46826V version which is reprogrammable, and I want to take advantage of the possibility of programming it on board with the I2C of the STM micro. The device I read and write regarding the re...
