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...

Posted on February 04, 2016 at 14:56Guys, How can I print fr to UART ? fr = f_open(&MyFile, ''STM32.TXT'', FA_CREATE_ALWAYS | FA_WRITE); HAL_UART_Transmit(&huart1, fr, 32, 1); // Debug I got this error : ..\Src\main.c(85): error: #167: argument o...
Posted on February 05, 2016 at 01:50I am using a STM32F072RB discovery board and trying to calculate the voltage on a pin (PA1). I attached VDDA to the pin and measured the voltage with a voltmeter and it is 2.97 V.The raw value that is read using a...
Posted on February 04, 2016 at 23:31Hello I am planning to use 16MB SDRAM on F469 for grx applications. I would need something that works seamlessly with FMC on F469. The F429 Discovery Kit uses 8 MB from ISSI but winbond offers the same size for mu...
Posted on January 28, 2016 at 02:45I've turned up nothing relevant in forum and web searches, so I apologize in advance if it turns out I've overlooked something painfully obvious.I'm experiencing an issue with (SWO) debug output via printf(). When ...
