ADC STM32L433RCTx
Hi, While working on Nucleo Board for STM32L433RCTxx, I have configured 9 ADC channels for taking voltage inputs of 1.6 to 3.0V from individual cells of the battery. I am able to get the readings but they are not consistent, a few channels are missed...
NUCLEO-H755ZI-Q how many gpio
Hi! Im looking for a microcontroller with a lot of gpio. I have looked into NUCLEO-H755ZI-Q. As I understand it shall provide me with 144 gpio but im not sure if I need some header for this to happen? I have read about ST Zio and morpho connectivity ...
using CN5 in STLINK-V3MODS
Hello,I have an STLINK-V3MODS debugger, and I want to solder the 14-pin target JTAG socket. I see that there are messing components around when comparing the file "UM2502" page 13, Figure 7. MB1467 top layout to my real debugger. I see lots of missin...
Resolved! How to change the (STLINK_V3E) MCO HSE Frequency
That is the ST-link V3 on NUCLEO-H755ZI board.The HSE MCO option is set to HSE/3, how to change it to HSE/5.Usually this is configurable in code, but this is ST-link firmware. If there is a way to change the division value, please some one let me kno...
NUCLEO-G031K8 using external 5V power supply issue
Hi,I'm powering my NUCLEO-G031K8 from external 5V (LD2 led is On as expected) but the MCU stays in reset state (Vnrst=1.32V). I've changed the NRST_MODE to 1 (Reset Input only) with no success. The embedded ST-LINK is driving the MCU reset but in thi...
STM32H7 very hot
Hello dear community,I've started using STM32H743VGT6 on a custom board I've made.I'm testing the hardware now and I quickly detected that the temperature is really high (approx. 70°c on the top of the chip package).I have another board, based on a S...
STM32F103RB Enabling TIM Peripheral Clocks
I recently learned about Timers and I looked through the RM and DS of the MCU and I am trying to set up my TIM6 but it seems that I cannot even enable any Timer peripheral clocks in the RCC_APB1ENR register at all, I can write to bits 31-11 but bits ...
Resolved! Nucleo-F429ZI -- Cannot get a USB HID device to send keystrokes to the system
Hi Everyone!I am pretty new to the community and STM32. I have been trying to set up the Nucleo F429ZI board to act like a an HID keyboard and send keystrokes. I have initialized the USB_OTG_FS to Device Only, USB_DEVICE to HID, and as far as I can...
H755 Hard reset no error and soft reset in debug mode has error
I create project with CubeMX, use Keil MDK IDE, CM7 core without user code , CM4 core has simple user code. Download code to both CM7 and CM4 then code runs correctly. Then switch to debug mode for CM4. Now, if i press Reset button on board or press ...
