Using STM's MDMA example, I setup a simple loop to transfer an array of 1000 bytes 100 times.The code worked but the MDMA transfer were causing glitches on the VDD rail.I then compared it to memcpy, and to my surprise found that it was around 18% fas...
Posted on December 05, 2014 at 10:05i'v tested the nucleo on arm mbed, very nice. but, when i use the onboard stlink v2.1 to debug my application board, the mbed mass-storeage disk is always pop-up a window. so, can i disable this disk (not by disba...
Hi,I have a power management setup with a smart battery, charger Ic and the host msu - all connected on the SMBUS. I am facing some issues and I doubt that the data on the SMBUS is getting corrupted. The issue is only happening when the MCU tries to...
Hello,I've got some questions about STM32H753 PLL setting. 1) There are many configurations of M, N and P parameters that give the same output clock. Are there some configurations that are more precise than others (regarding the output clock) ? 2) Th...
Hopefully this is more of a sensible non-noob question, it relates to interrupt handling, in my case a simple USART receive interrupt. I can see how the CubeMX tool is managing the .c file, its created an interrupt handler, for me to insert my code, ...
Hi,Currently, I am facing an issue with STM32 MCU I2C communication.I have facing an I2C timed-out error on the host side while communicating with the MCU I2C continuously.The I2C clock line was held low when the issue occurred, I wasn't able to comm...
Dear ST Community, I am currently working with the STM32L433RC board, specifically utilizing its 12-bit ADC. Despite my efforts in writing a simple program, I have encountered accuracy issues with errors exceeding 4.5%, and in some instances, even su...
Hi,I use stm32h743zi nucleo board and I try to GPIOx_BSRR register .This register has two 16 bit registers "BSRRL" and "BSRRH".As I understand BSRRL is used to set bit and then BSRRH is used to reset bit.GPIOB->BSRRL =(1<<0); to set the zero p...
Hello, I'm using a STM32 F446RETx trying to trigger an ADC conversion on PA0. I use TIM2 Channel 1 using a pwm with no output to trigger the ADC 1 conversion on channel 0. I have exactly one line that trigger an error at compilation (When I comment i...
