Posted on August 28, 2013 at 08:58Hi, I have a batch of STM32's which use the LSE. On all of the device LSE starts normally(i.e. you can see it oscilate with a scope). However, on a few of the devices LSERDY never aserts to indicate that the clock...
Posted on August 28, 2013 at 12:46 Hi, I set an interruption handler for a timer. Each time it calls the handler I change the state of a IO. But I'm getting problems for frequency above 80kHz. If I set the period to: TIM_TimeBas...
Posted on August 28, 2013 at 11:17Hi everyones,In the datasheet for STM32F407xx, in the electrical characteristics part (12-bit ADC characteristics), they deal with the Rain value. they define it like that : used to determine the maximum external im...
Posted on August 28, 2013 at 10:30Hello all,I am using an stm32f105rc as an usb host to manage a cp2102 with freertos and st host stack.I found a problem with USBH_BulkReceiveData: sometimes it issues two bulk requests so I miss a byte.The connectio...

Posted on August 26, 2013 at 09:41Hello I tried to migrate a working SPI master from a STMF20x device to the STM32F37x device. The SPI master should write and read 8bit data to some SPI memory devices (EEPROM or flash) by using DMA. Attached is the ...
Posted on August 28, 2013 at 04:01Is it possible to run a stm32f4 project with Atollic TrueStudio without a board? Likefor 8 bit microcontrollers? That is a limitation of Lite Version?
Posted on August 27, 2013 at 23:08Hello! I've been wanting to increase the ADC/DAC setup in my design using the STM32F407 chip but I am having a hard time understanding what specific functionality I can use to get more than 2 in / 2 out over a singl...
