Resolved! STM32L476Vx LQFP100 w/ external SMPS
I was looking at the STM32L476 datasheet (https://www.st.com/resource/en/datasheet/stm32l476vg.pdf) and noticed there's no LQFP100_SMPS pin definitions (see Table 16 or chapter 7). All other packages seem to have an _SMPS section. Is this an oversigh...
Resolved! UART using st-link v2-1 break up from Nucleo F446RE
Hello,the UART is not working. st-link is stand alone (not connected to Nucleo anymore)i am using a separate stm32f446ret6, tx(PIN16) and rx (PIN17) are connected to CN3 (TX/RX).in addition the SWD CN4 of the st-link is used (all connections are made...
Resolved! Why NC is written on PF0 and PF1 pins of NUCLEO H743ZI2 though it is connected to microcontroller?
I am working on NUCLEO H743ZI2 and I want to use PF0 and PF1 pins as I2C2. But on nucleo board NC is written on these pins. Can I use these pins as I2C2?
Resolved! Why my Win10 PC keep downloading STM32 Virtual COM Port Driver Version 1.4 instead of 1.5?
I went onto the website to download their STM32 Virtual COM Port Driver Version 1.5 but instead my installation kept ending with Driver Version 1.4 being downloaded. Another problem is there is no Flash Loader Demonstrator.
Resolved! How to use the standalone ST-LINK capability of my nucleo after I cut the PCB?
Hello,in the user manual of my Nucleo L152RE, on page 16, it's written:"""Cuttable PCBThe STM32 Nucleo board is divided into two parts: ST-LINK part and target STM32 part.The ST-LINK part of the PCB can be cut out to reduce the board size. In this ca...
Getting inconsistent results between the ideCube and ST-Link Utility
I have two programmers ST-Link V2 clone and Blue Pill that was flashed with ST-Link V2. I was using the Blue Pill to program two other Blue Pills (BP).When using the ideCube: One of the BP would program as expected, but the second BP would throw thi...
I wanted to order an cortex M7 mcu,I currently using an stm32f1 series with stlink v2 clone.My problem is that im not sure which debugger/programmer should i order for cortex M7 series? .Also whats the difference between STLINK-V3MINI and STLINK-V3MOD
I read the manual and its says " The STLINK-V3MINI embeds an STM32 32-bit microcontroller based on the Arm®(a)Cortex®-M processor " same fore the VMOD but i wanted to reassure that im getting the right debugger/programmer?
Missing labels on STM32H750B-DK schematic
Hello -The schematics posted on the website for the STM32H750B-DK board do not have any of the off-sheet or power ports labeled. This makes it impossible to follow the power connections on this schematic:https://www.st.com/en/evaluation-tools/stm32h7...
