Posted on November 02, 2015 at 12:11 Hi everyone, I'm a newbie of embedded programming and this is my first post. I have a STM32L0 Discovery board and wanted to supply electricity to an external circuit. The external circuit ...
Posted on November 02, 2015 at 17:08I remember from the 1980s that my colleague responsible for the hardware had some trouble getting an oscillator for our MCU to work. But the last decade designing my own hardware, it seemed as if things had improv...
Posted on November 02, 2015 at 22:52My problem is that i am not able to write to SPI1->DR. I have a LIS2DH accelerometer on SPI1 and i am able to read �Who_Am_I'' register and it returns correct value. However when i try to read any other register v...
Posted on October 15, 2015 at 16:07Specifically it's the September 2015, DOCID027704, UM1884: Description of STM32L4 HAL and Low-layer drivers Version: 3.0 Size: 6,732 KB from the STM32CubeL4 page.Presumably this is just an accidental omission, but ...
Posted on October 31, 2015 at 08:21We are looking to make a product which would be SIL (level 2 or 3) compliant. In that product we use STM32F303.I would like to ask if any of you have experience with SIL? Especially with SIL and STM32 micros. Do y...
Posted on November 02, 2015 at 00:43Hi,I'm using FLASH to store some data. Everything works great when I write in an empty address. When I try to write in a already used memory position, the stored value becomes to zero!I tried erase the sector befo...
Posted on October 29, 2015 at 23:45 I'm currently experimenting with writing a driver for USART1 at the register level for the STM32F4 Discovery board. I've followed the initialization procedure on page 963 of RM0090; however, when I connect to ...
Posted on November 02, 2015 at 19:21In my design the STM32F107 is connected to the MICRELL KSZ8081RNG ETH PHY (which operates in RMII v1.2 mode).Using the LwIP i can transmit ETH packets to the network but cannot receive any data from the net.Can t...
Posted on November 02, 2015 at 14:51HiI'm using STM32F103 in our products. We have sold about 700 unit before.Now We are in second mass production.But we have faced with a problem that has been reported by the clients.Our device features are:- RFID ...
Posted on September 04, 2014 at 12:28Hello,I am a student that is designing a prototype with STM32F207VC. I'm trying to choose a 25 MHz crystal oscillator to have ethernet, with AN2876 guide. I see in this guide the recommend crystal STS25ASM , but ...
