Hi I want to detect a GPIO turning low/high in less than 1 mili/sec granularity.I can use an interrupt (edge) or I can busy/wait with HAL_GPIO_ReadPin which would be in 1 mili/sec granularity because of the systick.Is there any other way of doing tha...
Hello. I have an external circuitry that I want to monitor voltage. It can go up to 48V hence I have used a big voltage divider. I am using 220K and 10K resistors for my voltage divider.At the moment, I am measuring 24V external voltage. After the vo...
Since the initial configuration, the communication between Cube and the STM32F769 board has been OK.As I had a problem with the SDRAM configuration, I tried to solve the GPIO conflicts listed in the IOC.After a modification (I don't know which one) (...
Hi ST community members,I have SMT32 card and pulse sensor that allows to measure the heart beat (ECG signal). In fact, I want to visualize the samples of ECG signal at the output of ADC through matlab. More precisely, I want to present the samples w...
hello, my project was to do a over the air update, looking for various strategies and I found one in the vector website. https://www.vector.com/int/en/products/application-areas/embedded-software/embedded-trends/ota-update-approaches/#c230972This met...
Hi everyone,I'm doing tests with sigfox using the deboboad X-NUCLEO-S2868A2, and with the example everything works.However in the final product I will not have an EEprom where to store the sigfox credentials (id and Pac) and therefore I would like to...
It seems to start in main and debug just fine after this so I have just kept working, but I'm worried that there is something wrong that is going to byte me in the future. Should I be worried?
Here SysTick_Config(16 000 000) takes one second to count down from 16 000 000 to zero?That is, one tick has a duration of 1/16 000 000==62.5 ns ?0.0000000625(one tick time) *16 000 000 ticks== 1 secondCorrectly?At the end of each count, an interrupt...
I have set Timer 8 to PWM Generation CH2 CH2N. Based on the value read by the ADC, I want to change the polarity of both CH2 and CH2N. I have found that using __HAL_TIM_SET_CAPTUREPOLARITY, I could change the polarity of CH2 but the polarity of CH1N ...
My background is in hardware, but I have extensive experience writing "bare metal" code (C) for 8-bit MCUs, mostly for AVRs. In the past, I have used AVR Studio (now Microchip Studio), starting with version 4.18 down to present versions. Tool chain...
