Posted on January 28, 2015 at 10:38Hi,I�m newbie in USB projects with STM32, so I kindly ask your help to find what I�m doing wrong with STM32F072 and CDC USB.For now, I�m trying to send some chars through USB form microcontroller to USB PC with �CD...
Posted on January 27, 2015 at 11:08DocID15965 Rev 12 (January 2015) In section 17.3.15 on page 417 ''Using one timer to start another timer'' it says that TS in the TIM2_SMCR register has to be set to 000, but it should be 010 instead. Is there a s...
Posted on January 27, 2015 at 10:25My STM32f103C8T6 works as a slave. The SPI DMA worked fine if I put the NSS pin of the slave to the ground or set the pins config to software. But if I put the NSS pin of the slave to the gpio pin of the master, th...
Posted on January 29, 2015 at 08:10Dear All.I'm working with SMT32F103 USB function.STM32F103 board is mass storage device now.Now the PC recognize and can read/write file to internal flash memory of STM32F103.(Example: text file, bitmap file, jpeg ...
Posted on January 28, 2015 at 11:19Dear all, I am using STM32F0 discovery board to program my STM32F105 board. I am getting below errors, can any body suggest15:37:20 : The elf loader Program function fails.15:37:21 : Memory-Loader error15...
Posted on January 29, 2015 at 01:15Hi, While working on an STM32F427 design, I have encountered a few problems in the datasheet. In Table 10, the LCD and OTG alternate functions for PA11 and PA12 are listed in the opposite order relative to other po...
Posted on January 28, 2015 at 21:29Hi, I have figured out how to change the period of the Timer 3 on the fly by using TIM3->CNT = someNewValue; and it works good. However, the duty cycle requires updating as well, set up originally as PWM pulse (TI...
Posted on January 10, 2015 at 10:14Dear All,I would be grate if any one could advice me that in which page the SPI pin configuration is showing in the ''RM0091Reference manual'' STM32F0I mean, What are the proper Configure GPIO for MOSI, MISO and S...
Posted on January 28, 2015 at 14:26Hello there, I am using eclipse and arm gnu eclipse plugin. It comes with HAL instead of SPL. Most of the available examples out there are SPL and I need to rely on that as I am a begginer in STM32 world. So i trie...
Posted on January 27, 2015 at 14:10I'm new to STM32 board. Working with F103C8, currently I could use TIM2 (24M) as trigger source to start DMA1 to transfer data from GPIOB->IDR(15:0) to RAM. However I found the speed is no more than 8MHz during the...
