Posted on April 16, 2015 at 10:56Hello STM32-Community!I read in the document UM1472 that the 5V pin can be used as a input of an external power supply. I want to power up my board by using one battery (11.1V). I was thinking about a simple voltage ...
Posted on April 16, 2015 at 17:05 Hello, I'm relatively new to the STM32F4 family but have worked with other microcontrollers in the the past. I'm trying to use DMA to send 8bits of data at a time from a memory array to a GPIO (GPIO_C) using ...
Posted on December 24, 2014 at 18:00Hi, I have a STM32F3DiscoveryBoard. How do I update its embedded ST-LINK FW? I have the ST-LINK Windows utility but it says the ST-LINK HW is not in DFU mode. How do I set the embedded ST-LINK on the discovery boa...
Posted on March 17, 2015 at 18:40Hi, I have multiple STM32F4 discovery boards connected to the same pc. I use the ST-LINK_CLI utility to burn my user applications and reset them. Is there any way I can have access to the SN field that the ST-LINK_CL...
Posted on April 16, 2015 at 10:00Hello, I'm working on a custom board STM32l152 that include LCD (1/4 duty & 1/3 bias) I just want to enable all signal ( 64 = 16 * 4Com ) in order to check the screen. somehow only 1 (of 4) raw is working. this i...
Posted on April 11, 2015 at 23:57Wiil ask my question here also because there's no reply form support to it: It's not clear to me if there will be an STM32F411VxH, that's the 100pin F411 in UFBGA100 package. Don't see it (anymore) on the product pa...
Posted on April 08, 2015 at 14:50Hi,I have a problem with MDK-ARMV5 project generation if the project is located on a network drive. Everything else is generated.If I have the project on a local disk everything works OK. I know that this is a simple...
Posted on April 15, 2015 at 18:02Hi, I have several time strict TIMER ISR and I tested the execution time of one of them.The result is that 47 instructions(indluding 3 branch instructions) costs 3 us.My chip is stm32f103 and all code and data is...
Posted on April 15, 2015 at 09:36i am going to use 16 bit wide data bus in high speed (roughly 20mhz). so theoretically, i need to use one port? the problem is the lqfp100 package that the chip has, have all the port pins scattered. none of the port...
Posted on April 10, 2015 at 12:25I'm using a stm32f429 running at 144MHz and I wanted to implement a periodic two-channel adc conversion. I need to make the conversions on a 1us period and I'm considering in using a dma adc conversion. I know how to...
