Posted on June 10, 2014 at 16:34 For several years I have developed software for an STM32F103 target using Eclipse/OpenOCD/Olimex ARM-USB-OCD. Recently my hard drive failed so I replaced it and re-installed everything. My project will not now ru...
Posted on June 10, 2014 at 16:54Hi all, I have a project where I need to deal with 4-to-8 bit and 8-to-4 bit conversion and so I have a questions: 1. I know that I can do DMA to/from GPIO but what is maximum speed of that operation. Can I go up to 2...
Posted on June 10, 2014 at 22:17Hi guys, I'm working on ST32F4 DISCOVERY board. I generated a STM32cube project with freeRTOS + FatFS + USB-OTG-FS as Master and it doesnt work. USB LED (vbus) is not light and the USB key doesnt receive any voltage. ...
Posted on June 04, 2014 at 04:47Hello I am trying to send opcode bytes MCBSTM32 to GP22. But as I debug in Keil I observe the the byte to be sent(0x50) is nit being written on the SPI data register in stm32f10x_spi.c. Instead the data register is sh...
Posted on June 05, 2014 at 22:21Hello, I want to transmit 10000 samples taken by adc continuously stored in an array. Is it possible the DMA-UART can transmit this to the PC while the CPU can take the next set of samples(independently) i.e wit...
