Resolved! Output Pin
Hi, I have a Nucleo 144 - STM32H743ZI2 and I need that the output pins deliver 5V, no 3.3V. Is it possible?Thanks

CCM-RAM performs worse than FLASH because of PC-relative loads
Hi guys,I am trying to optimize interrupt latency and execution speed on an STM32G474.The natural thing is to use the CCM-RAM for what it is intended... while it potentially lowers the interrupt latency, my code actually performs worsewhen executed f...
CAN TD does not reach VCC on STM32F412CGU6
I am using a STM32F412CGU6 and selected PB_9 to be the CAN Tx pin. The pin then idles at 2.8 volts. If I use it as a standard IO pin, it will go to 3.3 volts. If I assign the CAN Tx pin to PA_12 it also idles at 3.3 volts.I am using mbed 5.12
Need flash organization for stm32f429bit6
According to the ordering information, this device provides 2MB of flash.But table 6 on page 77 of the reference manual that shows flash organization for stm32f42xxx devices shows only 1MB of flash, although it says "2 MByte" in the heading. This see...
Resolved! TSC Channel selection
Hello Everyone!I have thoroughly understood touch sense controller peripheral of STM32F051C8T6, I have also developed a test code using the HAL layer and is working file and detecting touch (i.e. is count value decreasing when finger comes near elect...
Resolved! Can an MCU that supports QSPI use OCTOSPI memories?
I want to add some volatile memory to my MCU (32~64 MB). I'm currently looking at STM32H/F7 devices.Most DRAM needs so many traces that the PCB area taken up by the memory makes it impractical for my design.It seems like there is a new memory interfa...
STM32H750 + QuadSPI PSRAM chip: would it work?
I wonder if STM32H750 will work with QuadSPI PSRAM chip (for example ESP-PSRAM64H) and map it into the memory natively? I've read in the datasheet that MCU supports Flash chips via QuadSPI, but what about PSRAM?
How do the driver files from the firmware link to a program?
Can anyone help me with connecting the drivers that are missing in the example program I am trying to build for the audio recorder?I have tried everything I can think of and the program won’t link the header files. I am have tried to add the header f...
STM32F407 spurious reset (RCC_FLAG_PINRST)
Hi, I have a project using STM32F407 micro. Every few days I get a reset on the device even though there is no interaction with the device. I have it running on the debugger with ST-Link connected and when this reset occurs I inspect the CSR register...
