Hello,We are facing the situation in which, we have to differentiate that USB charging is going through the PC or adapter. We are using STM32L4R5 controller.We tried with the "HAL_PCDEx_BCD_VBUSDetect()" API but always getting call back for the "PCD_...
Hi all, I have a STM32F091CC and am using SPI2 on PortB, Pin 13-15.I configure polarity=0 and phase=0, but the trace in logic analyzer and oszi shows that the clock is idle high. I have already tried pullup, pulldown and nopull at CS pin, but with n...
I am trying to understand build boot loader with flasher loader demonstrator application. I came across this problem i.e., I could not able to select port in that application. I am using windows 10, Any inputs are much appreciated!!
Dear All,What is VOS range while using external regulator for STM32H743 ?Thanks,
In our design we use QUAD SPI for memory interfacing, can we use QUAD SPI separately for two different memories.
From the datasheet diagram (attached), it seems like the DMA has access to all of above. However, it is not clear whether it is really possible to DMA data to / from those and how I should do it and I've seen negative response to similar chips, so I ...
Hi all,I am trying to design PID controller to monitor LED temperature Control Variable: Parameter that adjust the LED brightnessProcess variable: LED temperature (measuring it with sensor) I am looking for some tips to tune my PID parameters as well...
I am trying to control the amplitude of a triangle wave, while the frequency of the waveform should always be 1kHz. Is this possible to do?The reference manual says that I can control the amplitude of the signal using the register DAC-> DHRx. Further...
I'm using the STM32F303xx MCU in an application with a 24.576MHz crystal. The MCU is powered from 3.3v. I am currently clocking the processor at 3x 24.576MHZ, or just slightly under 74MHz. I realize this is above the rated maximum processor clock ...
