Posted on May 13, 2015 at 13:26Hi everyone, I want to interface an STM32F429IIT to a SI4735 radio chip using the I2C interface. The SI4735 programming manual says, the status bytes should be read after sending a command. My problem is, that the firs...
Posted on May 14, 2015 at 16:09Good day,I want to make stm32f401 act like slave for my project.Can you tell if this schematic will work?
Posted on May 15, 2015 at 14:04I need my device to call a number using the SIM900 GSM chip and play a *.wav file from the flash to the SIM900's microphone. I have no experience with audio and I have 2 questions: 1. Is it possible to use microcontrol...
Posted on May 15, 2015 at 08:02Hello everyone, i would like to ask for your knowledge. I am new in Cortex programming (my only experience is on Adruino platform) and i have managed to blink the LEDs on my Cortex device (it's an STM32 conStick fro...
Posted on May 14, 2015 at 18:09Hi,I have a very strange problem with the SDRAM controlling and PG2 pin use. I use SDRAM as an additive memory space so it is vital for my program because I do calculations that need a lot of space. This works very wel...
Posted on May 06, 2015 at 13:03I want to have a sample of system clock at MCO pin of STM32F107RC micro controller. I use dspin firmware library for driving stepper motor. The on board crystal is 8MHz and system clock set to be 72MHz. I add this code...
Posted on May 15, 2015 at 07:22Hi,I am trying to do a project for school, where I am just trying to measure the power consumption of the board running my algorithm, but I would like to measure the board with ALL LEDs off. I was wondering if it's pos...
Posted on May 13, 2015 at 22:22Hello. I try to work with external sdram AS4C4M32S-6TIN via fmc interface.It has got 4 internal banks. When i write data in first bank all ok.But there is a problem with others banks.When i write data in one of the thr...
