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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Posted on April 15, 2016 at 14:34I want to make the CRC progress as soon as I receive bytes so I want to calculate partial CRCs as soon as the packet is entering the system. Should I use HAL_CRC_Accumulate with buffer size =1?I also deal with bytes ...
Posted on April 20, 2016 at 16:42Hi, New STM32. Im doing a design involving STM32F042G4. Is there a reference design for this IC? I have found - http://www2.st.com/content/ccc/resource/technical/document/application_note/c9/19/d7/b8/6b/0e/4c/d3/DM00...
Posted on April 20, 2016 at 00:03hcan is locked permanently in HAL_CAN_Transmit_IT when all transmit boxes are full. Bellow is compressed HAL_CAN_Transmit_IT function: HAL_StatusTypeDef HAL_CAN_Transmit_IT(CAN_HandleTypeDef* hcan) { uint32_t tran...
Posted on April 20, 2016 at 12:47HiI admit I am a complete newbie so please go easy.... I need to store some variables in the 5 memory locations in the STM32F091RC. We have the following code:mark1 = 123;RTC_HandleTypeDef RtcHandle;RtcHandle.Instan...
Posted on April 19, 2016 at 17:18Hello, all ???_rcc.c files, e.g. STM32Cube_FW_F7_V1.3.0/Drivers/STM32F7xx_HAL_Driver/Src/stm32f7xx_hal_rcc.c define const uint8_t APBAHBPrescTable[16] = {0, 0, 0, 0, 1, 2, 3, 4, 1, 2, 3, 4, 6, 7, 8, 9}; This contrad...
Posted on April 20, 2016 at 10:31Hi Every body... Recently i wrote a program to read a file from uSDHC Card 4GB for infinite loop. Purpose is check the total time of reading a file (eg mp3 file). The code is so simple and noting have any complexity....
Posted on October 18, 2015 at 00:09Here is original function static HAL_StatusTypeDef I2C_MasterTransmit_TXE(I2C_HandleTypeDef *hi2c) { /* Write data to DR */ hi2c->Instance->DR = (*hi2c->pBuffPtr++); hi2c->XferCount--; if(hi2c...
Posted on April 15, 2016 at 18:17Hi,I'm building a time trial race, to do this i'm using the STM32F334R8T6 microcontroller with the RTC and timestamp, resolution must be of hundredths of a second, for this type of project is correct to use a RTC clo...
Posted on April 18, 2016 at 23:16I had previously received the following response on this question from this forum...This is not a known issue and the part has been shipped and used in this manner already in K units without any returnsUse the standa...
Posted on April 19, 2016 at 13:32 Hi Everyone. I’ve been trying to calculate the phase angle between two sine waves differing only in phase, and I’ve got it working in MATLAB, using the FFT of each sine wave and then applying MATLAB’s angle functio...
