Resolved! Which is better: lower prescaler (PSC) value or lower period (ARR) value?
Hi, I wonder which one is better for Timer setup:lower prescaler (PSC) value and higher period (ARR) value?lower period (ARR) value and higher prescaler (PSC) value?

TIM1 doesnot enter CC interrupt
hello dear forum,my 103c8 blue pill doesnot enter TIM1 CC interrupt although there is square wave at A8 pinthe variable which I increment inside interrupt routine doesnot count I can see TIM1 counting in CubeIDE I am missing something but I cant f...
Resolved! Out of range channel written in ADC seq register for STM32L475
Hi,What happens if I write them out of range channel numbers in the ADC sequence register.For STM32L475, the channel range is 0 -18 but I wrote the channel number 19. While debugging, from debug window I found that the seq. register accepting number ...
Advanced TIM1 and TIM8 won't drive output as PWM mode as output
General timers work fine as PWM. Using TIM2, TIM3, TIM4 and TIM9 as well. They all work.TIM1 and TIM8 the advanced timers will not drive output pin, no matter how I configure unit.Using external clock 8Mhz as clock source, have tried internal clock...
FSMC - Multiplexed vs Non-Multiplexed mode on LQFP100 packages
I have used the FMC successfully in several projects to memory-map certain devices in a Non-Multiplexed mode where separate data and address lines are assigned. On devices with smaller package (e.g., STM32F407) the FSMC is only available in multiplex...
Alternate blocking and interrupt UART reception
Hello, everyone.I'm working on a project based on an STM32L4 MCU. My project needs to receive some commands asynchronously, to start and stop processing and tune internal parameters. I also need to be able to stream large chunks of data in and out.I'...
Resolved! AS4C16M16SA external SDRAM with STM32H745 Interface Driver
The STM32H745I-DISCO evaluation board used MT48LC4M32B2 as external SDRAM. But due to unavailability and pricing we had to chooses AS4C16M16SA part. But could not find any reference driver or wrapper for touchgfx for this IC under cube projects.Can a...
Resolved! ST25RU3993 Migrations
Hi,I am working on the ST25RU3993 UHF eval kit and done the required testing & other feasibility tests accordingly. Now for further development we are facing issue with shorting of STM32L476RGT6, based on searches I have found one replacement STM32G4...
Resolved! I'd like to use the same firmware for different types of MCU.
Hello everyone,I faced a shortage of MCU materials.So I found an MCU that uses the same pin map.I would like to change STM32F767IIT to STM32F767IGT.Please let me know if the change is okay.Clock does not work when using STM32F767IGT. If...
