Most 12bit ADCs of ST are specified not very accurate in DNL, INL, and total unadjusted Error. Especially DNL allows worst case scenarios of results being non-consecutive. I use these ADCs for several years now for slow signals and found ways in HW- ...
Hardware tested and functional.Commands modified on QSPI example (STM32Cube_FW-F7_V1.15.0) and the erase, read and write commands are functional.Problem to develop an externa loader, based on STM32F769I-EVAL example(using SW4 and MDK-ARM).The MDK_ARM...
I have written a TSC code for STM32L476RG . I have attached a sampling capacitor of 47nF and have connected it between sampling IO pin and GND. I have another capacitor which I have connected between a channel IO pin and GND. I want to measure the va...
Hi Team,I'm using STM32F030c8 micro controller, my application is to interface SD card with Stm32.stm32fxx to micro sd card interface:- pa5-----------clockpa6-----------misopa7-----------mosipf5------------csI'm using stm32f0 discovery board and exa...
So I've made two prototypes of a new custom board with a STM32F405RG microcontroller at heart and while one of them works totally fine, after a few seconds or more I'm getting a hard fault on the second one.To investigate the origin of the hard fault...
HelloI'm working on a STM32H743 and do have a question regarding read/write/eraseoperation on a flash bank. The h743 does have 2 Flash banks which are connected each to the axi bus.Reference manual says that it is possible to erase an sector on one b...

Hi All,Some of the grander Evaluation/Discovery boards use an STM32L152 as a slave Multi Function eXpander with an I2C interface. It's pre-programmed with firmware that provides access to some of the peripherals on the board.As it happens, I'm about ...
