How can I read the level of the BOOT0 pin after boot? Is BOOT0 pin sampled when protection level 2 is enabled?
I would like to be able to read the BOOT0 pin level at boot.I tried the following. It reads the BOOT_MODE from the SYSCFG register:// Turn on blue LED if BOOT0 is low at boot if (__HAL_SYSCFG_GET_BOOT_MODE() == SYSCFG_BOOT_MAINFLASH) { // BOOT0 pin...
Resolved! Syntax of startup_stm32g030xx.s
Good afternoon,Maybe is an obvious question.I'm studying the default startup_stm32g030xx.s, a part of the syntax is figured out in the program manual of MCU and another part in the GNU AS command page.But, for example, those following commands: .synt...
TVREFINT Internal reference startup time - - 2-3 ms
Hi,From the data sheet of STM32L072xx it is mentioned that Tvrefint start up time is 2-3msec. When using Vrefint in comparator, does controller take 2-3msec each time to compare input with Vrefint or it is just the initial start up time?Because I hav...
STM32H7 IEEE1588v2 Clocking
Assuming that STM32H7 is configured as a clock slave with IEEE1588v2 (LAN8742A as PHY), can the received/sync'd clock signal be fed into the internal clock tree to produce 32.768MHz clock output? If so, do any signals need to be routed from one ball ...
NUCLEO-H743ZI2 SDIO interface, how to utilize SDR104 data rate?
I am using a NUCLEO-H743ZI2 to read 16-bit data in via GPIO pins and store that data to an SD Card. I would like to achieve an average write speed of 20 Mb/sec for data sets up to 10 Gbytes. I am using 4-bit wide bus and have wired an SD card holder ...
Tips for maximizing performance and minimizing latency of interrupt handlers on STM32F0/CortexM0?
Also, what is the minimum time (or instruction cycles) to begin servicing an interrupt, i.e., how long does state saving take at minimum? Where would I find this kind of performance information? I am using STM32F031G6.
