Posted on November 14, 2016 at 21:35Good day,What I want is: If I put GND to GPIOD_4 I want to LED ON.If high impedance then LED OFF.I attached my schematic with CHRG pin connected to GPIOD_4.Is it possible to pull up internally gpio?I wrote some co...
Posted on November 16, 2016 at 13:18We are trying to implement Position Independent Code (PIC) on STM32F479NI. We have used -fpic and -msingle-pic-base options while compiling the code. Initially we wanted prove that this PIC concept will work on a ...
Posted on November 16, 2016 at 06:27Hello!Sir:I have a project which is the MCU(STM32F427) to drive the camera module(OV5642) and referenced the arduino web site (https://github.com/ArduCAM/Arduino/tree/master/ArduCAM) to setup the register value fo...
Posted on November 16, 2016 at 06:42Hello,I am trying to configure pins D0-D15 on the STM32F429VIT6 to output sram data. The code seems to be functioning properly and I have scoped out each of the pins however Pin44(PE13)-D10 seems to never go high....
Posted on November 16, 2016 at 17:00Hello STM32 group. I don't post a lot, but frequently read and benefit from the conversations on this board so I wanted to update you on something we've recently spent quite a bit of time debugging.We created an ...
Posted on November 16, 2016 at 10:25Hi,Currently I implemented SPI communication to external device using Nucleo-64 stm32f401RE.SPI implementation is based on Bit banding and not the HW SPI.Clk rate is ~3.2MHzSince the Nucleo-64 is used to communica...
