I have the STM32H747I-DISCO, and am interested in connecting a larger touch display. What possibilities are there? What limit is there on display resolution? Could a 2560 x 1600 display be used for example (I do not need video. I just need larger phy...
Hi, Please suggest STM32L562 UFBGA-132 Fanout guidelines.I looked into STM32L562E-DK design files for fanout, in which signals are routed in top and S1 layer but there is not via details for layer transition from top to S1. Here attached the fanout f...
Hi everyone, I’m trying to use the STLINK-V3MODS Bridge GPIOs (GPIO0–GPIO3) as digital outputs, but none of them show any voltage change at the pins — not even in Open-Drain mode with an external pull-up. All API calls (InitGPIO / SetResetGPIO / Read...
I have configured WWDG Timer in CM7 of Stm32H747I-Disco and configured WW1RSC=0 in RCC global control register (RCC_GCR) for CM7 Reset only instead of system reset.Issue:HAL_WWDG_EarlyWakeupCallback is getting called before watchdog Reset. but afrer ...
I purchased a Nucleo-L476RG eval board and downloaded the PWR STOP2 RTC example code to test for a low power application.After following the instructions for the jumper settings outlined in UM1724 for external power, I built and tried the example. Th...
I have an STM32L4R on a custom PCB. I am able to flash firmware using CubeProgrammer/CubeIDE to it via an ST-LINK SWD connection as well as a DFU Bootloader via a USB D connector. I have a makeshift connection between the USB D connector to a USB C c...
I cannot get the VCP function of ST-LINK v3 mini working.Windows sees the com port and can open itConnected TX output of UART to pin 14 of ST-LINK 3 mini, but nothing is received on the PC side.Connected some other serial TTL-USB adapter (set to 3.3V...
Hi all,I'm trying to use Livetune to make an mp3 player but it only works once connected to a board. I have a custom Nucleo-U5A9 (originally a Nucleo-U575, I replaced the MCU and added xtal). I'm reading UM3297 Getting started with X-CUBE-AUDIO-KIT a...
Hello, I'm using (ISM330DHCXTR) accelerometer to calculate the phase difference between two axes to measure the movement of a system. configured ODR at 6.6 KHz and measured the operation frequency of the system which has a 10% error while measuring t...
