Hello, I don't know whether this is appropriate place to ask, But will STM32H7A3RIT6 or H7B3RIT6 a good choice for projects considering availability? Are these in production to use on new products and trust the availability exists? Thank you!
Hello everyone, I am working on a custom device that is using an stm32 L433. One of its peripherals is set to generate interrupts to wakeup the device from the stop mode, but there are certain instances where I need it to stop for 30 seconds or so an...
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...
