MCU boot
I designed Control card using stm32f205vet6 and it working good. But when I changed MCU to stm32f205vbt6 I have boot problem. boot address is 0x1fff3de4 so MCU is not working.

High jitter on MCO output?
I just got my NUCLEO-H723ZG board, I loaded the GPIO_InfiniteLedToggling example project, downloaded the program to the board and it worked fine. Then I added a very simple code to output the HSE clock to an MCO pin. /* Enable the MCO1 Clock */ LL_...
Resolved! Solved; STM32F437VG: remove AF for a JTAG pin (pin 0x0F) make it be a GPIO.
I use `HAL_GPIO_Init()` to configure my GPIO pins, setting my `GPIO_InitTypeDef` structure initially to zero and then configuring the Pin, Mode, Pull and Speed parameters as I require but leaving Alternate at 0 since I do not want an Alternate functi...
Extended CAN2.0B filtering in List mode problem
Hello, In my system I have extended canbus with 29b identifier. With mask filtering it looks to be working, but list filtering gives me problems; ( i have setup where on STM32 is sending data with with any ID I want, and second is capturing data as w...
How to active WS2812LED on stm32G071CB?
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...
Interrupt not working after jump to code from bootloader
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...
Resolved! Timer Compare output enable on multiple pins
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...
Input Capture: How can I compare the values in a circular DMA buffer?
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...
Resolved! I2C - Send "Measurement Request" to HIH6130 IC
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...
Problem with RTC backup registers
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...
