STM32U0 is the first Cortex-M0+ with a static consumption of only 160 nA in standby mode with RTC (Real-Time Clock) and 16 nA in shutdown. It also achieves 118 points in CoreMark and targets SESIP level 3 and PSA level 1 focusing on firmware code pro...
Posted on December 07, 2017 at 16:56Hello,I have a problem with the STM32H743.I have a pluggable SPI connection and the STM32H743 works as a Slave in receive mode.When I pull and plug the connection the NSS, CLK and Data connections toggles and I ge...
Posted on November 08, 2017 at 10:11Hello,I have read several documents about the Cache, but the last sentence in AN4839 (Level 1 cache on SRM32F7 Series) confuses me.' However, If the external device is an ASIC and/or a FIFO, the user must disable ...
Posted on December 08, 2017 at 10:48Hello everyone.I have a strange problem where my SPI data seems to 'shift' and my DMA goes out of control (I do not have a clue why it is acting as it does). I am developing a program using the STM32L433CC togethe...
Posted on December 08, 2017 at 08:44I found there is an uniq device serial number in BlueNRG1 datasheet, and it's address in 0x100007F4, but when I try to read it, they are all 0xFF, and the memory content in keil memory dialog is all 0xFF. My board...
Posted on December 08, 2017 at 08:32Hello,I'm trying to start the DFU bootloader of an STM32F4 Controller.I have my own bootloader implementation and I try to jump to the DFU bootloader from my bootloader.My Problem is:My Firmware is connected to CA...
Posted on December 07, 2017 at 10:21 Hello all, I am using STM32F030R8T6 and also using HAL libraries for programming. I am using two UARTs one as a debug UART1 to send various messages to PC and UART2 for communication with Bluetooth module (...

Posted on December 07, 2017 at 03:29I own a NUCLEO-L053R8.Is it appropriate to get a I-NUCLEO-LRWAN1, plug it into the NUCLEO and use the I-CUBE-LRWAN (STM32CubeExpansion_LRWAN_V1.1.2) to start learning LoRaWAN?Is the NUCLEO-L053R8 with the I-NUCLE...
Posted on October 19, 2017 at 18:16I just upgraded from v3.9.0 (having previously used most versions since 2.5.0) and now connecting and disconnecting are seriously degraded. Specifically, after physically disconnecting the programmer from our board...
Posted on December 07, 2017 at 23:56Hi everyone, I'm using one STM32F4 and I want to communicate with my LSM303 accelerometer. For that I'm using I2C, and just using I2C works fine but when I try to use DMA with it, it stops working. When I use HAL_...
