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...
Hi,My RAM_D1 is almost full, mainly because of LTDC frame buffer, etc., I need to use RAM_D2 and RAM_D3 for my variables, arrays and other staff. I am using RTOS CMSIS v2.There are a few posts about using RAM_D2 and RAM_D3 in H743, in the forum, but ...
Hi allI'm working with an stm32f4 and I have a question about current consumption on stop mode, on the pin PC1 I have a external pull up 10k connected to 3.3v, before stop mode what is the best mode to avoid PC1 consume 0.33ua ? Right now I have put ...
