Resolved! [B-U858I-IOT02A Discovery Kit] Octospi configured to memory mapped mode for NOR flash
Hello,Today, I'm using the MX25LM51245GXDI00 external flash memory on the demoboard B-U585I-IOT02A to store some data and to retrieve them using STM32CubeProgrammer. In order to do it, after erasing a sector (4K bytes), I configure OCTOSPI2 (dedicate...
STM32 Internal Flash Write/Read Failure
Hello everyone!I'm writing a STM32F446RE-based flight computer for a rocket. I want to use internal flash memory to keep some key data like base pressure or flight time. So if a power failure happens, the system can keep the base data.These are the t...
MHz frequencies on OUTPUT
hey thereI have a stm32f103 blue pill board which I wish to generate MHz frequencies on pinC13.I have used TIM1. it starts and interrupts and on each interrupt I toggle PC13like sovoid HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) { if(hti...
Help with debuging a for statement in BluePill
Hi, I'm using a base64 library to convert my data to my base64 on STM BluePill. everything works fine, but after 5 minutes i receive an imprecise data access violation hard fault error on a for statement. i'm using main loop to run my code every 1 se...
Resolved! Does micro detects low power?
hey there I have a question: can a micro, say stm32f407 detect low power? for example is there a HAL function to indicate VDD lower that 3.3v?(this way any time that power is going, I can for example save everything before power off)
How to use the STLink BRIDGE API - UART bridge?
I want to use the STLink BRIDGE API and setup a C++ project. So far the GPIO worked fine, next I want to use the UART. I found the following Warning in the docu: "UART "bridge" is not supported on the STLink USB bridge interface. This functionality i...
Internal temperature sensor shows big offset at temperatures > 50°C (STM32G474VE). Is this common knowledge and if so is there some form of formula to correct this?
Setup:Using ADC1 with an ADC frequency of 50MHzSampling time of internal temperature channel = 640.5 cycles = 12.81µs (> minimal sampling time of 5µs)Conversion triggered every 1s by softwareUsing injected channel since regular channel conversion is ...
