Posted on January 02, 2016 at 20:59I want to store consecutive Timer counts (32bit) to a text file. To avoid SDIO write for every count, I've tried to store in a string first and SDIO write after 40 counts (for example). Can we store values column-w...
Posted on December 26, 2014 at 23:28 Hello I'd like to run all three ADCs of the STM32F405 in regular simultaneous mode and use DMA to load the values to a buffer. I'm sure this problem has occurred before but all the examples I found ar...
Posted on October 13, 2014 at 23:06hi, i'm going to make my own dsp board with a stm32f407vg. i developed my firmware on a stm32f4 discovery and so i'm tryng to reproduce the part of that board i need on my custom pcb. as well as connect the pin of ...
Posted on January 01, 2015 at 11:28 Hello, I am successfully communicating between the nucleo board(master) and a TI(slave) launchpad using normal SPI. e.g I can send a long character string from nucleo and receive it correctly at the lau...
Posted on January 01, 2016 at 10:07We are using STM32F205. Circuit is working at 3.3V Most of the critical components are 3.3V. I need to select proper BOR level.Datasheet states following:00: BOR Level 3 (VBOR3). reset threshold level from 2.70 to ...
Posted on May 18, 2014 at 17:55Dear friends, I am really inclined to use the STM32F050 microcontroller. I would like to use its internal bootloader, but while I was reading the documentation (AN2606), I found the following: ''The hardware required t...
Posted on December 30, 2013 at 14:52I found a LCD with OTA5182A driver in SPI & RGB interface. However its RGB is serial RGB not parallel RGB in STM32F429. Is there a way to allow the LCD controller to work with STM32F429 inside lcd display? #int...
Posted on December 31, 2013 at 16:40I am trying to make USB works on Sony SmartWatch with STM32F205RG. I don't have scheme but I am 90% sure that watch uses PA11/12 for USB FS. I addopted ST's USB FS library and currently I have this : - watch is de...
