ADC high precision challenge
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- ...
ST Link External Loader development for STM32F746 board using a QSPI NOR flash from ISSI.
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...
How to measure capacitance value of capacitor while using TSC ?
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...
SD Card Interface with STM32F0
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...
Getting a hard fault on only one of two identical boards
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...
STM32H7 read while erase Flashbank and sector erase time
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...
Pointer to struct inside a union throws hard fault.
struct {unsigned char oned; unsigned char twod;}test;hspi2.Instance->DR = *((uint16_t *)&(test.oned));struct {unsigned char oned; unsigned char twod;}test;this works fine.however,typedef union { struct { uint8_t idType; uint32_t id; uint8_t dlc; ...
Have you seen the source code to the MFX?
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 ...
How to get 4 channel input capture values from stm32f407 ?
