Hi All,I'm playing around with the Timers at the moment on a STM32F303 and currently have TIM2 and TIM6 generating an output pulse on every OC event (different frequency ranges).Those Timer based output toggles are of course somewhat locked to certai...
Hi!I have Input Capture enabled with DMA. It works.My buffer is 2 elements and it's a circular buffer. Each element in the buffer gets the counter value from a timer and the counter value goes from 0 to 65535 at 6.5535 seconds.Question:I want to comp...
Hi, I seem to be having difficulty with what should be a simple I2C task. I want to send the Measurement Request to the Honeywell sensor so it will take a temperature and humidity reading, which requires the following format from their datasheet:I ha...
Hi,I’m trying to use RTC backup registers in STM32G070KBT6. I wrote this code but I only receive FFFFFFFF at serial output. How Can I fix this problem?Thanks.RTC_HandleTypeDef hrtc;void setup() { HAL_RTC_Init(&hrtc); Serial.begin(9600); Serial.printl...
Hi! Jest a curiosity topic.Currently Im writing a double word to flash with HAL_FLASH_Program function.RM notes that You should write a word32 and than to the same adress another word32.How can You write a 2x_word_32 or 1x_doubleword_64 without HA...
Hi, I am using a DAC example code available in repo of STM32F7 package for STM32F746 discovery board to test on chip DAC. The example code is configured for DAC channel 1. I need to configure for DAC channel 2, how to do it? I tried changing the mai...
I'm very new to stm32. I want to port SQLite to my STM32F407. I tried adding the SQLite amalgamation libraries to the code file but the code refuses to build due to several issues. I tried to search for a anything that describe how it's done in the i...
Hello,In my STM32F429 design I am using SP4 in master mode to read data from a slave with DMA in half-duplex mode. The setup is DMA2/Stream0 for RX and DMA2/Stream1 for TX, normal mode and no FIFO for both. Communication works without fail without DM...
I'm bringing up my own STM32G030F board. I've gotten the "blinky" program to upload and run, but all attempts to change the moder of the GPIOs fail. At first I was using the proper macros but I've resorted to changing the MODER explicitly in my code,...
Hi, I've been working with this device for a while.Today I started to try to write the option bytes in order to turn PF2 into a GPIO, which I did by writing an assembly file, compiling, and flashing via debug in Keil. I use a Segger J-Link as USB SWD...
