I have a bit of code as follows:str r3, [r0, #68]ldr r3, [r0, #68]where [r0, #68] is TIM20.BDTR on a STM32G474. I would expect that the LDR would output the same data that was just stored, however it seems that out outputs the previous data. I al...
MPU:STM32H755XI6Connection with PC:USART1RTOS:ZephyrIn order to install Zephyr into STM32H755XIH6, if you build and burn images for M4 and M7, the M4 side will start but the M7 side will not.The content is LED flashing of PG10 (A9pin). Are there any ...
Previous post: https://community.st.com/t5/stm32-mcus-embedded-software/dma-on-stm32l011f4/td-p/742092 I am working with code on the STM32L011 that uses DMA to read data from USART2. I received excellent help on this forum before and I'm hoping fo...
Good morning, I am trying to print a string on STM32F401RBT6 using vs code and Cmake, but I keep getting an issue, when I use '\n' the UART doesn't print nothing beyond the '\n', can somebody help me with this issue, please? printf("Hello\n World");
Hi, The reference manual says - "In differential input mode, the analog voltage to be converted for channel “i” is the differencebetween the external voltage VINP[i] (positive input) and VINN[i] (negative input". "In single-ended input mode...
We used I2C bootloader for STM32G071GBU6N (UFQFPN28) more than 3 years. We bought a new batch of controllers STM32G071GBU6N. Bootloader does not start. I tried to debug bootloader and if I stop program then old chip sets at the address 0x1FFF2128 bu...
I am using STM32F423RHT6 in my project. I am using 2 ADC Channels for measuring Voltage and Current(through Current Sensor). But I am facing a strange issue. Where the channel corresponding to the current is getting accurate values of analog voltage....
Hello,I'm facing a very strange issue with timer PWM in DMA mode.I use the PWM channel to send step pulses to a stepping motor in order to free the mcu while the motor is moving, rather than using time consuming delays.The issue raises when I change ...
Hi,I see from the MX file for the display project for STM32U575ZI-Q with GFX02Z1 display to have following pins assigned. I have question on these pins objective and I have tried to explain my understanding. Please suggest if my understanding is corr...
I’m encountering an issue with my STM32H755 application after moving the flash memory to accommodate SBSFU. The Reset_Handler address in the vector table is misaligned by one flash bank. Here are the details:Background:Microcontroller: STM32H755Bootl...
