Posted on August 11, 2012 at 02:46Hello,1. What is the maximum SPI speed I am suppose to achieve with the 8MHz HSE? 2. I would like to achieve at least 25MHz, what would it take to achieve that both code and HW? Currently with my code below I get 13...
Posted on August 12, 2012 at 15:25I want to use the HSI, and the code is like the following: void RCC_Configuration(void) { RCC_DeInit(); RCC_HSICmd(ENABLE); RCC_AdjustHSICalibrationValue(0); RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA|RCC_APB2P...
Posted on August 10, 2012 at 12:09Hi. I m just complete with a project using a STM8S. I went through development with a STM8S-discovery, which is by the way a great evaluation tool : cheap, and no useless peripherals such as LCD. Just had to solder ...
Posted on August 13, 2012 at 11:35Good morning everyone,I managed to make my LCD Display work by using a simple ''delay'' function which counts the time I need to wait.I also use quite a lot a interrupts in my project.The problem is: If an interrup...
Posted on October 10, 2011 at 15:27I am working on stm32f217 144pins. I try to connect signal I2S3_SCK to stm32 but all two pins (pin nr 111 and pin nr 133) which provide this connection are used by other peripherials.These pins share functionality ...
Posted on August 11, 2012 at 21:22Hi, I'm new to this forum and was wondering if someone could maybe assist me with this problem: I'm using the STM32F407IGT6 device for one of my projects. I want to use both CAN busses on the device. Currently CAN2...
Posted on August 11, 2012 at 10:32Hey guys, does someone knows why access to peripheral memory location (0x40000000 - 0x5FFFFFFF) can't be done with normal LDR and STR instructions. It works fine in simulation but when flashed in the chip, the memor...
Posted on June 14, 2012 at 10:08Hi to All, Setup: STM32F4DISCOVERY board connected to SMS USB3320 HS PHY. CPU Clock : 168Mhz from HSI. USB Class: MSC - mass storage device. Problem: The device descoravble by PC I can see files on the Flash disk but...
Posted on August 10, 2012 at 13:16Can any one tell me where to find the firmware of Example given in the application note AN3126. Thanks.
Posted on August 07, 2012 at 20:21Hi all, I'm having problem stopping the SPI clock in RXONLY mode. PB3(SCK) and PB4(MISO) on my STM32F103VBT6 are used to read from a bunch of external shift registers. On-chip resources are allocated as follows:SPI1...
