Posted on May 21, 2014 at 03:52Browsing through the STM32 F405 datasheet, I'm noticing serial ports with functions listed multiple times even on the same chip. At first I assumed (for example, USART1 TX) would be listed multiple times, but on any gi...
Posted on May 18, 2014 at 22:43Hi,I used the stm32f3 discovery board to test some code and it works fine but when I run the same code on a custom breakout I made around the stm32f303cc it runs for a while and then stops.The time it takes for the boa...
Posted on May 17, 2014 at 23:48I trying to send continuous serial data at 115200 baud using USART2 which is connected to the ST-LINK portion of the NUCLEO board. ST-LINK implements a VCP which I'm accessing via a terminal on my PC. If I space the ...
Posted on May 20, 2014 at 16:46Hello,I am trying to get the reference voltage value with ADC (Channel 18).On the VCT6 datasheet, it is said that reference calibration values (for VREF) are stored in memory at the address 0x1FFFF7BA. (Value for VREF ...
Posted on May 20, 2014 at 14:34hi, everyone.i am using STM32F3 Discovery Kit to communicate with Arduino. i use EWARM IDE for coding and Putty, for serial terminal.i did an echo test on stm32f3 usart2. The data is displayed on the serial terminal co...
Posted on May 19, 2014 at 14:04Hello Everyone,I was just wondering if anyone has seen this, I have seen this only referenced on one website. I have SPI1 on a STM32F415 configured as PA7 ------> SPI1_MOSI PB3 ------> SPI1_SCK PB4 ------> S...
Posted on May 19, 2014 at 21:41I'm wanting to update a product that has a SPI device on the same channel as the UART. Currently the SPI device uses DMA - it sends 1 byte and receives a packet of info. On the UART we only send data.I would like to ...
Posted on May 19, 2014 at 22:52Hi I made VCP from ST sample on ST32F405 (STM32_USB-Host-Device_Lib_V2.1.0 & DriverVer=04/25/2010,1.3.1) When I send data from CPU to PC less than 64 byte, all work fine. I have 2 problems: 1) When I try send data from...

Posted on May 15, 2014 at 16:58Hi, I am using USB HS port in the FS mode in my vcp project. When I used it to communicate to PC, it works ok if I re-plug in the device to PC. The problem is if I just reset the MCU from IDE debug, the device cannot ...
