Posted on October 26, 2015 at 19:42I have a NUCLEO-F401RE board. I tried to find its connector pin out, because the schematic diagram is made with some hobby tool and useless. All the doc document files use some odd format I can't read opened. I tri...
Posted on August 21, 2015 at 21:31Hello! I apologize for my bad English, but I do not have anyone to ask. My task is to create a USB host to work with flash pametyu. I also use fatfs. I'm using a microcontroller STM32f407VG. To create a project I us...
Posted on May 12, 2015 at 00:20Hi,I worked for several weeks on a dictaphone project with the board F429 discovery. The goal is to write the values of the ADC to a file on a USB key.My ADC works with DMA, everything is ok.However, I generated my f...
Posted on October 27, 2015 at 12:28I am Facing a problem to use TMR2 and SPI3 in STM32F103. I am using Keil Software to write the code and the Problem is if i remap and choose SPI1 TMR2 will stop working and if i stop using the remapped SPI1; the re...
Posted on October 21, 2015 at 14:59Hello, why do the recent STM32Cube Headers still keep BSRRH/BSRRL in the GPIO_Typedef in STM32Cube_FW_F3_V1.3.0 while STM32Cube_FW_F2_V1.2.0 drops BSRRL/BSRRH in favour of BSRR as used in the other headers This ma...
Posted on October 11, 2015 at 15:07This is relation to my previous forum post [DEAD LINK /public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/Flat.aspx?RootFolder=/public/STe2ecommunities/mcu/Lists/cortex_mx_stm32/STM32F030F4%20ADC%20strange%20behavio...
Posted on October 26, 2015 at 13:55Hi, I hope someone can help me. We do have some strange behaviour with our STM32F4-Discovery Boards. Currently we capture analog data on two channels. Both channels are configured equally. Despite equal configurati...
Posted on October 27, 2015 at 11:37hello everybody !!! I'm using ''__HAL_TIM_GET_FLAG'' on my STM32l051K6 for detect an overflow on my timer, but i don't know how much machine cycle it takes ?Could someone tell me how this function uses machine cycl...
Posted on July 23, 2015 at 12:19Hello. There is a bug in the cmsis_os.c file: at line 757: return xQueueCreate(queue_def->queue_sz, (uint32_t) sizeof(queue_def->item_sz)); sizeof(item_sz) is always 4, so all queues are created with element size = ...
Posted on October 26, 2015 at 14:47 On an stm32f411 Nucleo, I'm trying to generate a DMA request to transfer data from memory to the USART2 data register at every compare event (when CCR1 matches TIM3_CNT). To this end, I have, in order: ...
