Posted on February 16, 2016 at 17:32 I have run into a problem when trying to setup a SPI com between the STM32F4 Discovery and a CR95HF RFID. The MISO data looks correct in the scope, however the software reads the bit 0 as 0 always, giving me ...
Posted on February 18, 2016 at 01:43I'm using an STM32F407 (#1) connected to PC via USB and another STM32F407 (#2) via UART3. I'm trying to program #2 via the bootloader using STMFlashLoader.exe by initializing #1 as a USB CDC device and passing thr...
Posted on January 30, 2016 at 13:43Dear Forum Members, I am using STM32f103 custom board. I have divided my flash into 2 parts, one for custom bootloader and other for application(as explained in ST IAP example). Now I want to made boot loader secti...
Posted on February 18, 2016 at 09:48Hi i wonder if it is possible to read the changes on the GPIO pin where the GPIO pin is configured as GPIO_Mode = AF pin mode. on f429?
Posted on February 10, 2016 at 09:40 Hi all, I'm working with STM32F4 mcu and keil uVision 5 IDE. I'm tryng to configure RS232 periph. but I have a problem. Transmission works fine but I'm not able to receive interrupt when something is recei...
Posted on June 14, 2014 at 15:30I don't know whether this is related to the STM32CubeF4 package or the STM32F407 so I'll post here.I'm using the STM32F4 discovery board and the onboard USB FS port.I wrote a VCP interface that lets me send a buffer o...
Posted on June 24, 2014 at 18:02Hi guys,I recently upgraded my USB Host libary in one of my programs from version 2.0.0 to version 2.1.0 and it seems to have broken something. When I try to read a file from my USB Flash drive using FatFs, it crashes...
Posted on February 18, 2016 at 03:32I used a function generator send a signal to PA1, if PA1 get the high signal that let LED on. But my program can't work correctly. Always high or always low, depend on GPIO_Mode = IPU or IPD. Below are my program,...
Posted on February 17, 2016 at 16:44I built my own board and I am trying to use the JTAG connections. It does not seem to work. It only uploads a small percentage of time and even when it does, I am not to sure it is uploading correctly. I thought ...
Posted on February 16, 2016 at 08:16Hello there, I have a general question regarding the NJTRST signal in a JTAG protocol. In STM32 datasheets, I read that JTAG can operate with only 4 pins, without NJTRST. I only assume it then uses regular #RESET ...
