Hi all,I am stumped with an issue that looks trivial but apparently isn't really ?This code... :double TMP117ConvertTemperatureToCelsius(uint16_t temperature) { double temp_double = (double)temperature; double multiplied = (double)temp_double * 7.8...
From a previous question: https://community.st.com/t5/stm32-mcus-products/stm32h745-dac2-missing/td-p/750749 So I can get two independent analog outputs using STM32H745?
Hi, I would need dual DAC using STM32H745. According to datasheet, it should have two DAC converters. In STM32CubeIDE, I can see only DAC1 with two channels. In the datasheet, I can only see DAC1_OUT1 and DAC1_OUT2 pins, but no DAC2 out pins. Is ther...
I am currently working with an STM32U5 microcontroller and would like to request more information on the process of calibrating the RTC (Real-Time Clock). We are using an external 32.768 kHz LSE oscillator with 10pf burden capacitors, but we are obse...
SPI CLK frequency dividing methodIn microcontroller (STM32H43), SPI1, 2, and 3 use a common CLK Source.Is it possible to separate these CLK Sources?Also, I would like to divide SPI2 and 3 more than 256 divisions, but is that possible?Please help me.
hello everyoneI'm having problem with debugging stm32f103 blue pill with Keil 5.39 ans st-link v2 programmer.my programmer work fine when i load code without debug on micro but when i want to go to debug mode, my code run till the line__HAL_AFIO_REMA...
Hi,I’m using the STM32L76G evaluation board and would like to work with the CAN protocol. I have a DB9 connector but no slave devices. Could you suggest how I can test and work with CAN in this setup?
Dear Community, I started investigating issues on one old project that based on STML071xB and has been implemented by another engineer. I got confused with implementation of battery measurements. Here is the thing: 1. MCU is directly supplied by a ba...
Question about SPI communication intervalWe are using HAL_SPI_TransmitReceive to achieve SPI communication, but there is an interval of some us after the SCLK outputs for 8 bits. Is it possible to change this interval time?
Hello folks! One of my devices happened to have a some kind of flash corruption, enough that an ECC NMI was triggered. Removing the "while(1)" from the default handler, to simply return from that handler to my program, did not work. I was thinking th...
