Posted on February 24, 2012 at 04:24Hi, I recently noticed that my STM32VL Discovery board, while powered from the USB port would only output 2.5V on any of the pins. I checked the 5V and 3.3V outputs on the board, which only delivered approx. 4.5V...
Posted on March 07, 2012 at 16:05I encountered a data alignement problem when using the 3 ADCs. ADC_Mode = ADC_TripleMode_RegSimult ADC_DataAlign = ADC_DataAlign_Right had no effect. Data was allways left-aligned. The Problem was that I omitted assi...
Posted on March 07, 2012 at 11:03Hi,I would be grateful if someone could show me how, using C language or by using a line of assembler in a C program, I can force storage of a variable in a register r0 and upwards in an STM32. Even a very basic exam...
Posted on March 07, 2012 at 15:21Hello, we use the STM32F103xx series for a long time now and want to know if it has boundary scan cells. Where can i find more information about the boundary scan possibilites of the microcontroller family of ST ? Fr...

Posted on March 06, 2012 at 05:20I'm trying to implement USB device that emulates mass storage on USB FS, however, the data source is approx. 10 times slower than USB FS transmit rate.I tried to wait in Mass Storage read callback for data, but it ...
Posted on March 02, 2012 at 21:28Hi, I am trying to update the fash of STM32F407 by using the Flash Loader Demo V1.3, but it does not seem to communicate to my processor. I used this program to flash my STM32F10x series, but I don't know if it will ...
Posted on March 06, 2012 at 23:49Hello, We'd like to program debug on TWO STM32 Cortex M3 CPUS with a Keil ulink Pro with Samtec FTSH-110-01 Cortex Debug+ETM Connector. We only found how to daisy chain the JTAG but not the ETM trace. Suggestions ple...
Posted on February 29, 2012 at 13:22Hi, I'm almost done finishing my STM32F4 Eval Board. But I still have a few questions: I want to use the internal regulator so I connected Vcap1 and Vcap2 with cap's. There is still this PDR_ON Pin. should i leave...
Posted on March 02, 2012 at 11:49Hello. I'm trying to connect two stm32f4discovery boards through I2C. One will be the master receiver, and will ask for 4 bytes of data to the other (slave receiver). I found an example for the master receiver, and i...
