Posted on February 05, 2016 at 23:28Hello!I'm trying to use a generated code by the STM32Cube software (for a STM32F205 device) to read a sequence of ADC channels using the DMA in circular mode, and I'm facing some annoying problems: The code is s...
Posted on February 02, 2016 at 17:01Thanks for any help. I'm confused on how to connect VREF+. I see that it can be used as an reference voltage output, and I now have it as No Connect. VDDA is connected to its pin, which seems to provide the voltag...
Posted on January 26, 2016 at 10:54Hi friends , I found following and did not understand why __set_MSP(0x20002000) , why main stack pointer hold 0x20002000 ; why not 0x20000000 (sram start address) for stm32f429. When I debug and look in 0...
Posted on February 04, 2016 at 14:21Hi all: I am developing a device with an STM32F407. The device will always be powered by its own power supply. It will have a USB socket so that it can act as a ''USB device'' (a USB slave) that shows up as a s...
Posted on February 05, 2016 at 11:16 I am working with the ST-Link Discovery development board and I'm trying to get the SPI-bus working properly. I have configured SPI1 as my master and SPI2 as my slave and I connected wires in between them. I ...
Posted on February 04, 2016 at 14:33 Greetings mates, I have a curious question... I am using ITM_SendChar and ITM_ReceiveChar as simple and lightweight comm interface for a STM32F4 discovery. But, is it possible to develop a standalone application/...
Posted on December 15, 2015 at 18:08It seems that in version 4.12.0 LwIP is broken. Code that worked with previous version was running without problems. Migration made code stop working. Tested on Stm32f407 discovery + expansion board (LAN8720).
Posted on July 17, 2015 at 04:14 Hello. I'm trying, for the first time in my life,to implement the printf/scanf functions on GCC. I managed to get the UART working in interrupt mode but somehow I can not do the easiest part. That is, I...
Posted on February 04, 2016 at 10:18Hi, I want to use the hardware control of SPI3-NSS pin. I wrote a code for it on the Discovery board with the STM407VG and it works as intended. I use the drivers from the older Discovery bundle, not the STMCube. ...
Posted on January 11, 2012 at 11:08I've spent (too many) hours trying to figure out how to use the CCM for something useful. And with useful I mean easy access from my code written in C. I use GNU GCC, etc (the Yagarto toolchain). At first I thought...
