Posted on November 14, 2014 at 10:39On stm32f407, Erasing a 128KB flash sector takes about 1 second, but after I finished erasing 1 sector, the systick just happend for 3 times(3 milliseconds), as I config systick as 1000Hz.Does MCU disable systick ...
Posted on November 14, 2014 at 00:18Hello ST gurus! Our company is seeking to protect its IP as much as possible from code extraction before products are shipped. We understand the STM32F4xx has protective features to prevent code extraction via JTA...
Posted on November 14, 2014 at 18:14Hi, I'm just starting on ARM CORTEX and STM32 via The Spark Core so forgive me if I'm missing something but in file stm32f10x_tim.cFunctionvoidhttp://stm32.kosyak.info/doc/group___t_i_m___exported___functions.html...
Posted on November 14, 2014 at 14:53Hi I am using STM32F205 for my project (SN8000 EVK from Murata).The SN8000 EVK uses Wiced SDK but it supports all the libraryfunctions, so the basic configurations will work(It uses vector tables in the vector_ta...
Posted on October 16, 2014 at 12:25Hello all,I'm attempting to talk to two devices, a barometer (MS5611) and a magnetometer (HMC5883L), using I2C with DMA on an STM32F4. The barometer runs on a timer (10ms), while the magnetometer runs through an in...
Posted on November 14, 2014 at 14:40As far as I can see the new STM32Cube has callbacks that are called from the ISRs. This means that all variables that can be changed within the callback and accessed from outside the callback has to be declared as...

Posted on November 14, 2014 at 01:07Hello, I need a way to flush the usart2 receive buffer . Will the following line do the trick or is it necessary to do something with the received rubbish bytes? // If buffer contains garbage, do nothing while (US...
Posted on November 13, 2014 at 16:32After replacing STM32F407VGT6 for equivalent VET6 I'm puzzled what parts of flash have been left out. This isn't described in the datasheets/manuals. Only the part number identification says 512k, but nowhere what...
Posted on November 12, 2014 at 19:08I'm planning to use the FSMC to memory-map registers of a FPGA. To save pins I would like to use multiplexing between data and address lines. Now, I need only a 8-bit data bus width but would like to address more ...
