Hi,I notice in the STM32H747XIH6 reference manual (RM0399) that "During and just after reset, the alternate functions are not active and most of the I/O portsare configured in analog mode." I want to confirm that in "analog mode" the IO is an HZ inpu...
IN AN4899, figure 18, it states:"To reduce power consumption, setthe pin as a push-pull output anddrive it in the same direction as theinternal pull-up / pull-down resistor.Alternately, set pin as analog input."I'm a little confused here. If there is...
Good Morning,We're looking at using an STM32H753ZIT MCU on a project, but we need to know the freely available revision due to the bootloader differences across revisions, or at least how to tell which revision version we'll be ordering (should we or...
Hi.I got a new (never used) STM32L031K6T6 chip. Put it on a breakout board. Add a 0.1uF and a reset switch.I am powering the chip through the st-link.Tried it with BOOT0 High & LOW. did not work.What I found weird too is that the REST pin is always L...
Hi, for my diploma project I made a DSP guitar effects pedal - designed a custom PCB and everything. On it I have an STM32F405RGT7 and a TLV320AIC33IRGZT audio codec. The codec is set up using I2C. The problem occurs when I try to communicate with it...
Posted on April 05, 2018 at 19:39Hi, everyone!I am quite new to SSL/TLS and I am trying to make SSL server on my own STM32F427 MCU board. I already have the standard HTTP server working correctly using lwIP netconn library and I now am trying to mak...
Hello,I am trying to use the CRC module on a STM32G491 (bare metal). But I simply can not get the same CRC as when I calculate it with some online tools.Withhttps://www.lddgo.net/en/encrypt/crcandhttps://www.sunshine2k.de/coding/javascript/crc/crc_js...
Hello,I am using a NUCLEO-G431KB with IAR EWARM 9.20.2 and trying to achieve a 250 ns ADC conversion time on ADC1 (IN1, Single-Ended mode).Configuration: 12-bit resolution, 2.5 cycles sampling time, ADC clock at 60 MHz (synchronous/2, SYSCLK 120 MHz,...
Hi All,I'm getting very frustrated about a weird behavior of STM32G0 microcontroller; why? because I did similar projects with members from different families and all work. So I don't know. Maybe I'm doing something wrong with this one.The applicatio...
Hello,We are trying to make use of the ART accelerator of the STM32F7.As a start we placed only a single part of code in the adress range of 0x00200000.And we enabled the ART accelerator in CubeMx as well as code prefetch.However when we start the co...
