Hi,I took code from:https://controllerstech.com/interface-ws2812-with-stm32 and made the adjustment to my MCU (stm32G071CB). but it didn't work.I manage to generate pulses from PWM with DC of 66% in 800K but not through DMA. I also try to ran it fro...
I have a project that consists of a bootloader and 2 pieces of code on STM32L100R8. The bootloader correctly switches to the relevant piece of code but it seems as though when the code receives it first interrupt it fails. Attached are screenshots of...
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...
