Hi every body! I chose STM32H755ZI MCU mainly because it has 1MB of RAM. In my project, I need to at least store 180 KB of Data. 45000 of float samples. I use the M7 Core which accesses the AXI RAM the size of which is 512KB; on the other hand, the B...
hi everyone, actually I have two questions. first: how can I create something like this char *main_menu[]={{"Work","start", "stop", "pause"}, {"Heater", temp_heater,"empty","empty"}, {"PREheat",temp_preheat,"empty","empty"}, {"Pneumo","forward", "st...
Hi,What is the difference between STM32H753ZIT6 vs STM32H753ZIT6U?I am curious because the U variant is on the eval card, but is not available anywhere. The non-U variant seems to have replaced it from all vendors.
Hi. i am a newbee here. i want to know STM32F411CC has sdio, does it support SDXC ?i need to use more than 32g sdcards. (example 64, 128, 256, 512g)if STM32F411CC only support SD 2.0 (SDHC max capacity 32g), SPI will support access more than 32g ??...

Hello,I am working with the STM32H745BI controller and would like to ask if there is a way to reset one CPU by the other CPU?So in my special case, I would like to have the M7 start up and check if the M4 FIrmware is correct. I would like to STOP & R...
I have no problem using an external signal GATED. An internal trigger connection as TRIGGER also works fine. But for some reason I can't use my internal trigger connection GATED. -What do you think I might be doing wrong? Any advice would be very muc...
Hi,I'm working with a STM32L475RC. The RTC is sourced by LSE and the CSS on LSE is activated.On every power on the LSECSSD bit in the backup domain control register is set. This means that the CSS has detected an error on the LSE. Now I'am wondering ...
Hello, I am looking to evaluate Cortex-M33 based controller for wifi connectivity use case. I found NUCLEO-L552ZE board. Does it support Wifi with any add-shield? or Do you suggest any other evaluation board with Arm security extension which would be...
Hi,I'm migrating a project from STM32F7 to STM32H7, and I'm hitting some roadblocks wrt DMA and the FMC.When I was using an F7, I was doing this to initialise the FMC, and it worked perfectly:/** * @brief Initializes SDRAM MSP. * @param hsdram:...
