Posted on December 14, 2015 at 04:10Hi. I'm fairly new to the concepts of DMA and I'm trying to implement DMA for my ADC on STM32F4 Discovery kit. Currently, I'm using ADC1, channel 4 which is the pin PA4 on the discovery. I'd like to know which per...
Posted on December 06, 2015 at 16:04hi,on a custom board, i ran into the following situation:usb is connected to PA11,PA12 and working fine.however, when reseting the usb subsystem pin PA7 is pulled high and remains high.this pin is supposed to be u...
Posted on December 10, 2015 at 16:18Hello, I develop power conversion controller and have one question. STM32-Nucleo have internally asynchronous serial junction between debugger MCU and target MCU. In ST-LINK/V2(-1) this feature not present. I can ...
Posted on December 13, 2015 at 06:25When we use STM32 chip, is there a limit for the size of array and subroutine?For example, if the chip has 128k ram, can I allocat 100k to an array(or buffer) or define an array as char chs[100k]? Certainly we nee...
Posted on February 12, 2011 at 21:39Hey, I just spent a bunch of time sorting out how to get the darn PWM output on the blue LED on the STM32-Discovery board. After a lot of time pouring over the datasheets and forum posts I was finally able to wor...
Posted on December 08, 2015 at 16:36HiI try to set an input capture on a stm32f100(rbt6b) I set a counter period of 0xFFFF, the problem is that when I retrieve the value, I have the feeling that the timer is overflow at 255 and not 65535 as I mentio...
Posted on December 09, 2015 at 13:20hi, in my project we are using virtual com port for a communication between pc(usb) and stm32f103(USB). But due to ground loop and noise we are facing communication problems. so, to over come this we are planning ...
Posted on July 29, 2013 at 10:41Hi,I want to make project NAND FLASH + STM32F4 DISCOVERY + USB MASS STORAGE, but isnt't easy ))I have any examples (Discovery\Open407V-D\USB HS Examples\Project\USB_Device_Examples\MSC) with MSC, but it works with SD ...
Posted on December 13, 2015 at 11:55Hi,I am new to STM32 controllers. I was doing blinking code. while debugging i got error as cannot access target.Shutting down debug session. I am using ST-Link2 for debugger and board is from - http://www.dhgate....
Posted on December 12, 2015 at 18:42Hi there,I am using a STM32F030C6 behind a buck stepping down a voltage to 5,5V, then a LDO regulating to 5V and finaly a LDO to regulate a 3,3V for the STM.At the scope, the 3,3V is almost clean. Still having som...
