I apologize for my english.I came across an incomprehensible thing for me (general experience with STM32 for about 10 years).I work with STM32L010K8. When I try to write to USART2->TDR, I fall into reset. Test on Keil and IAR, different optimisation....
Hi,I´m actually working with STM32L053C8 moden and i have some questions about how RTC works. I am using STM32Cube IDE and HAL libraries (C++).First, when i wake up (from standby mode) the microcontroller, the code always start from the beginning. Co...
Hello, I try to do with out compare, I use TIM out-compare feature and set TIM_IT_UPDATE interrupt, if go into TIM's update interrupt ,clear TIM's all register content , I config TIM second , of course ,same procedure, I config third TIM . second a...
Hi to all,I am not sure this is the correct forum, but I do not know where to put the question elsewhere.I need to interface with an SD card using SPI interface and I'm experiencing a big issue in write operation (CMD 24) because things quite always ...
In STM32H7x5 series, the MCU has 2 System Memory banks. Bank 1 is clearly described in reference manual, but not bank 2. My question is:What is the role of bank 2?Can user use bank 2 to flash homebrew bootloader?How to boot to bank 2?
Hi,My requirement is to use encoder mode of a Timer for driving pump. And using same Timer to drive the speaker. Timer 1 channel 1 would be used for Pump and Timer 1 channel 2 would be used for speaker. Timer 1 DMA is used to output sequence of pulse...
My project use STM32F030K6T6's ADC as AC 230v energy meter then upload to my website's server via ESP-07S. Now my design use HLK-PM01 AC-DC 5v and AMS1117 3.3v to power both STM32 and ESP-07S. Folllow AN2834 each VDD add 100nF ceramic cap + 4.7mF tan...
Hello everyone,For the first time now I need to write some data to the flash memory so it doesn't get lost when the board is turned off.I am using STM32F476-DISCO board. From the data sheet, I see that the main memory block contains 8 different secti...
WHICH ONE IS BEST?i have seen three methods:1, in_floating http://www.micromouseonline.com/2009/12/31/stm32-usart-basics/2, GPIO_MODE_AF_OD https://visualgdb.com/tutorials/arm/stm32/uart/hal/3, GPIO_MODE_AF_PP
