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...
Posted on April 30, 2015 at 12:12In programming manual (PM0056) in the description of ''Application interrupt and reset control register (SCB_AIRCR)'' two things are written: 1) Bits 10,9 and 8 defines PRIGROUP - they determine the split of group pr...
Posted on April 13, 2015 at 19:10Hello everyone, i want to seek some guidance. A friend of mine has given to me an small STM32 comStick evaluation board and i was seeking of some developers resources. I have already checked the various examples t...
Posted on May 12, 2015 at 17:52When using SPI2 PB12 is the NSS pin. However, I want to use PB12 as an output and not have it set or reset by the NSS when using SPI2. I thought I had done that by this line of code: SPI_InitStructure.SPI_NSS = SPI_NSS...
Posted on May 14, 2015 at 22:02 I am reading data from a ds 1621 on stm32f4 using i2c 1 on pb6 and pb7. Data sent by the device is fragmented into 2 bytes according to datasheet.I tried to read the first byte.It worked great.Then i decided to...
Posted on May 14, 2015 at 10:18Hi. I'm quite new into the STM32 devices, so apologies in advance for the scrappy code! I've got a STM32F429 Discovery board attached to a SSD1963 display though the FMC (8 bit mode at the moment), however I cant seem ...
