Posted on February 10, 2016 at 17:21I am using Embitz as IDE and a NucleoL152 as development platform.I tried this thing. An array of integers of 1024 elements (from 0 to 1023) was copied to two different arrays, one using CPU memory transfer and th...
Posted on February 10, 2016 at 10:11 Hi, I'm trying to get comms between USART1 and USART6 working. I can send from USART1 to USART6 using interrupts and it works. What I am trying to do now is control the sending interrupt, but I think I...
Posted on February 11, 2016 at 10:06 Hi. I need SPI to connect a radiomodule NRF24L I'm using STM32F429-discovery. According to the UM1670 pins PE2 trhough PE6 are free (nothing is connected to them). PE2 can be used as SPI4-SCK, PE5 – SPI4-MI...
Posted on February 11, 2016 at 20:21Hello,I am trying to flash my stm32429I-Eval via RS-232 using Flash Loader Demonstrator (v2.8). I set SW1 & SW2 high (BOOT0/BOOT1), and reset the board. Run the demo GUI with default settings (baud=115.2k, Parity=...
Posted on February 11, 2016 at 14:24 I am using an STM32L152 with the HAL library. I initialize the spi bus similar to the example code from STM32CubeMx. However, the very first spi transaction always has a wide extra clock pulse (see attachment...
Posted on February 08, 2016 at 22:47Hi, I am using STM32F10x controllers in a number of projects and have been programming these with ST-Link/V2 for a couple of years now with no issues at all. I just received a couple of ST-Link/V2-ISOL. These are ...
Posted on February 11, 2016 at 14:54I am new to the CPAL i2c library. Please help me make a code using this library to receive data from another microcontroller. ARM is supposed to run in SLAVE mode at 100kbps.
Posted on February 11, 2016 at 13:24Hi,Sorry if I've opened a discussion on an issue already solved...I've recently started a new project on a board with STM32F103C8 on it (the small cheap 40 pin board from ebay). I made the base project with CubeMX...
Posted on February 10, 2016 at 11:29Hi, at the moment im using a STM32F3 as custom FS HID device to send 1000 64byte packets each second (64kb/s) to host pc. i would like to increase the speed so im wondering which speed i can get with the external...
Posted on February 10, 2016 at 16:47hi, I'm using the STM32f407-discovery board example of DMA_FLASH_RAM.I've noticed by using systics for time measurements, that memcpy provides better timing than DMA.for example.I have 16bit array of 64 elements t...
