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...
Posted on February 04, 2016 at 10:22 Hello, I just learn about stm32 programming. I am using STM32L053 discovery board. Right now i learn about how implementing watchdog in my code. Here my code int main(void) { /* Reset of all ...
Posted on December 01, 2015 at 22:59I upgraded from CubeMX 4.10.1 to 4.11.0.Problem 1 (maybe not a big deal)When I opened my project, it said I didn't have library version 1.3.0. Which I do have. It offered to migrate to 1.4.0 or download 1.3.0. ...
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...
