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...
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...
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...
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 ...
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 ...
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.
I have been using the MSC_Standalone example to develop code on this DISCO board. I noticed that although the example makes use of the on board display, it only uses the top half. Is there a good reason for this and is there an easy fix to use the wh...
