I think it doesn't have an impact and you just get extra pins (e.g. extra SPI controllers becoming accessible) if going say 100 to 176. But it's not clear...IOW, will existing code run exactly as before? Isn't the silicon identical and they merely bo...
Content:Hi,I am using UART on STM32G4 in interrupt mode (RXNEIE + NVIC enabled). I observed the following situation: 1. A byte is received → RXNE = 1 2. At that moment, UART interrupt is disabled (critical section) 3. Later I re-enable the UART inte...
Hi, I am using STM32G474RE. I try to read out LTC2440 with the SPI interface. I have configured the LTC2440 as SPI master (In its datasheet the mode of operation is specified as Internal SCK, 2-Wire I/O, Continuous Conversion). The LTC2440 provides a...
hi, I'm using stm32h745 dual core MCU, in this i want to know about the caches.these I cache and D cache are default enable are it will enable from IOC configuration of M7 core.if not enabled from IOC still these caches will work automatically?due to...
We are using the STM32U5 MCU and its internal RTC in our project.We are facing an issue where the RTC time sometimes goes beyond 24 hours — for example, we observed a timestamp showing 37 hours. The RTC is configured in 24-hour format, and we have in...
Hello community,I am new to stm32, and I need to read the temperature from the internal sensor of a stm32g4vet6.I am at the point where I have read many things and have discovered that not all stm32's internal temperature sensors must be used the sam...
Hi,I'm using OCTOSPI in Mode Quad SPI on a STM32H563ZIT6. I'm having issues when reading Serial Flash data with a 1-1-4 (6Bh) read, 1-1-4 (32h) write is working fine. Also 1-1-1 read and 1-1-2 read also work fine. The serial flash is IS25LP032D. I...
Hi, I'm trying to do an external loader according ST's MOOC and this forum https://community.st.com/t5/stm32-mcus-products/stm32h5-external-loader/td-p/601134.My code pass on all ST's tests of memory, but when I generate a stldr it does not read on c...
Hello,I am using the VENC_RTSP_Server example located iSTM32Cube\Repository\STM32Cube_FW_N6_V1.2.0\Projects\STM32N6570-DK\Applications\VENCThis example shows how to use the VENC block and stream H.264 video through RTP/RTSP using Ethernet.I want to s...
Hi, I am using STM32H743ZI Nucleo 144 board for one of my application. As per the observations I got the utilization factor with STM32H743 is 35% where as with STM32H752 it was 60%. We have not initialized any crypto or secure features on STM32H753 b...
