Posted on December 21, 2017 at 12:46Hello,We are using STM32F030 in our project. We are using RS485 half duplex communication for interaction with other boards in our system. Using the same half duplex communication channel, we would like to update ...
Posted on December 20, 2017 at 13:27STM32F030.I am transmitting multiple words via spi to some shift registers and need to latch the shift registers when the transmission of the last word is finished. The latch signal is GPIO. Device is master.I don...
Posted on December 21, 2017 at 09:19For a long time I have been working with stm32f4 discovery board MB997C on my computer without problems. In fact, I've been running 2 boards simultaneously on my PC and it has worked great with both STM32 ST-LINK ...
Posted on December 20, 2017 at 04:45For Motor controller design using FOC sensorless prototype, there are 3 B-EMF signals need to be monitored by MCU. So I shall config 3 ADC channels for this purpose. But with ST MC WB there is no way to do this. w...
Posted on December 20, 2017 at 11:17Hey guys, I'm trying to do something that might be really a noobish thing (will ask in a different thread, and I recognize that there's a strange thing happening. I'm using an STM32 Nucleo64 L073RZI am trying to s...
Posted on December 21, 2017 at 08:39I have some problems connecting ST-link/V2 to STM32L0x1 device, especially with OpenOCDST-Link_cli.exe connects but log-file shows errors:Error (0x10) after target cmd F2 30 A3 00 00 00 00 00 00 00Error (19) while...
Posted on December 20, 2017 at 20:07My design has got a MMC storage chip (MTFC16GAKAECN-4M)(e.MMC v5.1 standard) connected to STM32F7 mcu. Provided I will be using FAT file system on this eMMC storage, is there a way to open this MMC storage as USB ...
Posted on May 03, 2017 at 16:29Hi,We are using STM32F072C8 device and we are using USB CDC Interface when communicating with PC.When USB bus traffic is low everything is working fine.But when USB bus traffic is heavy we observed during USB CDC Write...
Posted on December 21, 2017 at 03:52We have a project that using a wiegand sensor to power the mcu and update the counter to FRAM through SPI. there will be a 10us width regulated power supply from wiegand, all the process need to be done in 10us wi...
Posted on December 20, 2017 at 23:43 I'm new to microcontroller programming and I have a question. I'm trying to set up a stm32l152re card in the qtcreator and the same error appears at the time of compiling the project shrink arm-none-eabi-gc...
