STM32F429I-DISC1 powered with external PSU
Hello,I intend to use this Discovery kit together with a side board of my own.This side board needs to be powered by the Discovery board (to avoid ground problems) and could draw more than 100mA which, if I'm correct, is the current limit through the...
Resolved! Leakage current of STM32U585VIT3Q I/O when the Micro is not powered
HelloIn my application, I use the DAC of the Micro to charge a capacitor(47uF). When the micro is power off, the voltage on the capacitor start to discharge with a high impedance resistor(6.8Megohm). I want the leakage current of the Micro I/O small ...
The system works only with the ST link adapter connected
Hello,I use an STM32F767 microprocessor on a custom PCB and test it with power off and on conditions. After uploading the codes, I powered off and on the system. Then, the system works only while the ST link adapter is connected. Do you have any sugg...
Resolved! Why is I2C1 clock (PB6) also appearing on PA6? (L412KB)
I'm talking to a camera device on I2C1. That is working fine. I read back the data via DMA on a scan signal. This also works fine except for one bit, D6, mapped to GPIO PA6. If the output pin from the camera is connected to PA6, I2C1 stops working. F...
ST-LINK provides 8.08 MHz instead of 8.000 on new nucleo-H743ZI2.
Seems there is an error in the STLink firmware (upgraded to the latest version just now), clock is off about 1%.
In the schematic of STM32F030F4, the capacitor values are written 104, what is the unit of it?
I chose STM32F030F4 as MCU for my device. I have gone through its schematic (attached for reference). I have little doubt about it. The capacitor values are written 104, that's it. Please help me find its unit, I will be too much helpful.Secondly, I ...
Decoupling capacitor on STM32H7A3NG
Messrs ST,my customer has asked to me to replace their actual microcontroller with STM32H7A3NG: the more difficult thing is the placement of decoupling capacitors because their placement is not permitted on the bottom of the PCB (as best practice for...
