Is this connection real?I don't think so. DCACHE implementation subchapter says:The DCACHE1 is placed on Cortex®-M33 S-AHB bus, and caches only the external RAMmemory region (OCTOSPI, HSPI, and FMC), in the address range [0x6000 0000:0xAFFFFFFF] of t...
Hi,I am working with STM32G491RET6 and currently implementing the ADC. I have a question regarding the ADC reference voltage.If the external 3.3 V supply is removed from the VREF+ pin and VREFBUF is disabled, does the ADC operate using any internal r...
I am using STM32G491RE - NUCLEO.Similar to this post - ( https://community.st.com/t5/stm32-mcus-products/reading-data-with-brs-on-fdcan-line/m-p/745625#M266951)I implemented the function of receiving and transmitting data from the FDCAN line.I config...
HelloI trying to figure out what the maximum frequency is for the TRACECLK stm32u5A9.I found this post for the stm32h5https://community.st.com/t5/stm32-mcus-products/traceclk-freq-in-stm32h5/td-p/604127does the same apply for stm32u5 were can i in t...
So i was looking at the 16-bit ADC characterisics in the datasheet of STM32H723ZG. Here it says for LQFP packages, values might differ. I have LQFP 144 , and i can't find any package specific datasheets. Where can i find the information for my packa...
We have a STM32H725 and would like to use the RTC timestamp when entering/exiting standby but from what I understand from the reference manual this is not possible? I did run a quick test and the event doesn't seem to fire even though it works as exp...
Good morning,I'm developing a device with these requirements: STM32F446RET6No internet (NTP) or GPS connectionReal-Time clock, set manually (so, the less often a user has to set it, the better)Outdoor -20°C~70°C temperature range (most installations ...
Hi,I'm trying to generate a pulse of a fixed length when my application triggers it, on one of two timer outputs, depending on a boolean value. My problem is that it works only once. The first time I start the timer, I get a nice pulse, but the subse...
<Moved from this thread.>Just to confirm, did anyone else got success by using: for STM32H745, to safely power the uC with just LDO no SMPS ?
Dear, I'm using a STM32G0B0RET6 as MCU and I encouter a bug on GPIO external interrupt specifically on PC14. Configuring as external IT on rising edge, it works correctly and the interrupt is generated only on rising edge.Configuring as external IT o...
