Posted on February 04, 2013 at 15:44Hi, In my project, I have to measure the frequency of the input signal of an ADC. I use STM32F107 as micro and ADS1251U as ADC. is it possible? I will be grateful. Thnx for help :) #measure-frequency #adc-st...
Posted on February 02, 2013 at 20:59Hello! Just getting to know my brand new STM32F4 discovery board.Downloaded all the documentation, which is referred to throughout the site.Just thought I'd point out that athttp://www.st.com/internet/evalboard/pr...
Posted on February 02, 2013 at 10:43Hello ; It was not clear to me in the documents ; we are loading the program through usart3(stm32f407) ; so can we still have the code protect fuse? I mean we dont our code to be copied; when using Jtag it is ok...
Posted on February 03, 2013 at 10:19I use a microcontroller STM32F047VGT6 all alone without the kit board I want to use GPIO (I want to interface the GPIO Pin ) .. Is what I connects Pin directly without any electronic component?? #interface...
Posted on January 09, 2013 at 14:14 Hi all, How can I use the SDIO to access to an uSD card with EFSL filesystem. The example I have is using EFSL with SPI as communication interface. I should have an interface.c file where I do a...
Posted on February 02, 2013 at 21:45I has a kit Board STM32F4 Discovery WITH ST-Link / V2 .. I wanted to program/debug another microcontroller STM32F047VGT6 on my personal card .. I have to use the CN2 SWD STM32F4Discovery?? how I should SWD inter...
Posted on February 02, 2013 at 19:28Hello,I'm working on the STM32F4, and in my application i need to use atan2 and exp a very large number of times.In my initial implementation i used the stlib for atan2 and exp. Unfortunately, in the current state...
Posted on February 02, 2013 at 09:12I have http://www.sainsmart.com/sainsmart-stm32f103rbt6-arm-cortex-m3-mini-development-board-code-jlink-v8-adapter.html (board only), and I need a JTAG debugger to program it. Is it possible to use my F1 discover...
Posted on February 02, 2013 at 09:18Quick background: I'm using the STM32VL which has 1 ADC peripheral with a possible 18 channels inputs that are multiplexed to the actual ADC. I believe I have the configuration set up correctly for 2 analog inputs...
Posted on January 23, 2013 at 20:08Dear Friends; I use SPI protocol @ stm32f100c4 to interface with GLCD , to interface GLCD frame must be SPI 9bit. From Datasheet: Stm32f100C4 has two mode 8bit frame or 16 bit frame for sending data by SPI protcol...
