Posted on May 11, 2017 at 09:19Hello, I've designed my project using STM32F103RBT6. I've connected two switches to PC10 and PA10. Now I need external interrupt on both the swithes, but using cubeMX I'm able to set external interrupt to only one of t...
Posted on May 31, 2017 at 18:05Hi guys,i'd like to retrieve a FSR signal from PC0 pin (see jpeg attached for schematic) on my STM32F407VG-Discovery. I've to use System Workbench for STM32 as IDE and HAL driver. This is my code, it should light LED4 ...
Posted on June 06, 2017 at 10:06Hi,I'm using a STM32F103ZG with the Standard Peripheral Library, Version 3.5.0.I'm writing data (128 KiB) from an external SRAM (connected via FSMC) to an SD card (via SDIO). For this, I'm using the DMA-approach. (as ...
Posted on June 06, 2017 at 05:13Hi all:followed http://www.waveshare.net/study/article-656-1.html I could access my SD card through SDIO interface.uint32_t Buffer_Tx[512/4], Buffer_Rx[512/4];If I use var[128], it seems that I will get HAL_SD_ERROR_D...
Posted on May 27, 2017 at 04:09Is there anything I am missing while trying to get my STM32F777 chip into DFU mode?I have a 25 MHZ OSC (HSE), NRST is pulled high with a 10K resister and BOOT0(pin138) is pulled low with a switch to pull it high on res...
Posted on May 31, 2017 at 08:52Hi everybody,I have used STM32 HAL libraries to communicate with PC using USB CDC. I want to send a huge amount of data to PC and so, the communication speed is very important to me. However I could get very low speed ...
