Posted on June 11, 2015 at 17:11Hi there, I want to initialise the on chip EEPROM so I can save a number of bytes which will be Factory reset values. I don't want to use the Emulated EEPROM and I cant find any document regarding to that. I used PIC...
Posted on July 06, 2015 at 05:57Hi there! I've known that device marking ''YWW'' is datecode, where Y means year, WW means week. As there's only one char stands for year, how to distinguish year 2004 or 2014 if the code is ''4xx''? Thanks! #date-...
Posted on July 05, 2015 at 14:26Hi friends, looking for any project based on STM32F105 which can copy (Transfer) files from USB stick to On board SD card repeatedly. May be such a device can be used to batch copy files from USB stick to SD card with...

Posted on July 06, 2015 at 05:19Timer works in Input capture mode. It captures period of rectangular wave. I would like to get interrupt on each eighth front, but interrupt does not dependent of prescaler. Controller: stm32f030f6p6. There is code fr...
Posted on July 06, 2015 at 04:16I change stm32f0 source code to stm32f4.but, I have problem on TransferHandling function in stm32f0.stm32f4 has no that function. so i search stm32f4 example source. but it doesn't work.I2C2 is Gyro I2C, (PB10,PB11).w...
Posted on July 03, 2015 at 00:40Hi. I'm trying to program another target board (our design) with SWD by F4-Discovery board. I'm connecting, erasing the target MCU with STLINK/v2 utility but when I want to debug it with Keil v5.15 Lite Version it doe...
Posted on July 04, 2015 at 19:33 Hello all, i am trying to capture a ppm signal, for the moment i use a steady fixed widith signal of 740hz, with 1050us on period, and 300us off period. The signal going to PA0 and PA1 of my STM32F4 ...
Posted on July 05, 2015 at 08:25I used STM32F10x_AN2812_FW_V2.0.0 to have speex encoding /decoding on voice. I applied it on my Discovery board. I used encoding functions and then decoding one and saved the data in .wav format using FATFS on micro S...
Posted on July 04, 2015 at 19:37Hi, all. I wanted to use a portion of the STM32F303 FLASH as ''eeprom'' to store a block of data in a non-volatile manner. But I found the STM provided eeprom.c/h utility very cumbersome and restrictive, storing data ...
