Ask questions, find answers, and share insights on STM32 products and their technical features.
I might be missing a trick here, but it seems that most (if not all) DISCO / EVAL boards expose the same I2C bus externally that is used to communicate with onboard peripherals.This makes perfect sense with DISCO boards as they are small / low cost. ...
Hello All,I am developing a system based on stm32h757 dual-core M7 480MHz and M4 240MHz with external memory 4MB SDRAM. I would be glad to receive a recommendation regarding the right implementation. Firstly, I plan to connect external memory to M7 s...
Hi,This question is more a network protocol question than about MCU's however I am writing a driver for the Inventek and wish to use the built in mDNS server so the device may use DHCP and have a local host name.The Inventek manual doesn't explain wh...
In the cubeMX default code the order is:HAL_Init(); and then SystemClock_Config();HAL_Init() sets up the Systick Timer with HAL_InitTick().Afterwards SystemClock_Config changes the Clock setup (to HSE in my case), but HAL_InitTick() is not called aga...
Hi, I'm completely new to MCU programming, and bought my very first unit stm32f103c8t6 from a local store. I read some glowing reviews about it and bought it as my first ever MCU because it was affordable. Boy am I regretting my decision now! :( I ca...
In my project I'm use STM32F030C8T6TR MCU in this MCU programming memory is 64kb and ram is 8kb how can I add external memory and ram to MCU?
Hii How to calculate Flash memory write time?
Hi everyone,I'm getting weird values from ADC in a new board that I developed. It looks like it has an offset on it, but a big one.The analog signals arriving in the pins are ok. I tested with a scope. To make sure there was nothing wrong with the an...
I have a circumstance where two PWM outputs are required, and they must be precisely coupled together. A number of the other big guy's LPC micros included an SCTimer/PWM (that's State Configurable Timer...) which, without too much magic, allows a fi...
Hi,I need to get time from the RTC at a higher resolution than 1 second. I see there are two reg's that set up the thing for sub seconds, but I don't understand how to use them. I really only need tenths of seconds. I looked at the sub seconds regis...
