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 September 18, 2015 at 03:49Hi All, I am having an interesting I2C problem. A slave device i am reading from has a variable length response, the length of data is read from the device so i do not know how much i need to read until i start t...
Posted on February 06, 2017 at 14:22 I had problem for 'HAL_UART_Transmit_DMA', once I transmitted some data, I couldn't send any data after that. I used this function, 'HAL_UART_Transmit_DMA' in 'USART1_IRQHander'. (Because I should pars...
Posted on February 07, 2017 at 20:27Hi all,I have configured ADC to work in DMA mode for 4 channels. Code was generated via Cube. After I call function HAL_ADC_Start_DMA everything works fine until I trying to call other HAL function. In this case, ...
Posted on January 11, 2017 at 11:32Hi,I'm working with a stm32f437VI. I need more heap memory. I changed the Heap size in de startup_stm32f427x.s (Heap_Size EQU 0x00000200), but when I did a malloc and worked with the variable, and excepti...
Posted on February 06, 2017 at 18:09Hello,I'm trying to implement a software that will allow me to send additional one pulse (on the data wire and clock wire). After one pulse I should send data (32 bits) over spi.Frame should look like:1 bit + 32 b...
Posted on February 09, 2017 at 11:00Hi I need a target file (*.STmap) for downloading the STM32L031G6 using the 'Flash Loader Demonstrator' V2.8.0. I only got STM32L0_x3_x2_x1_64K.STmap, but STM32L031G6 is only 32K.
Posted on February 06, 2017 at 11:53Hello,I am having a problem getting the STM32 Embebbed Matlab/Simulink Target to run. I am following the example in the STM32_MAT-TARGET_HandsOn.pdf document for the third example (everything on STM32) step by ste...
Posted on February 08, 2017 at 13:19If the master sends the adress , but doesn't send the last clk pulse to receive the ACK from the slave, the slave will not release the SDA line. The problem is, that the ADDR-Flag only gets set AFTER the ACK was s...
Posted on January 27, 2017 at 11:16Hello All,I am using STM32F407 discovery board. I am using SD IO card with this board.I tried configuring DMA for data transfer.I observed that the interrupt (DMA interrupts) are not generated after Transfer comple...
Posted on February 06, 2017 at 12:34Hello, in my project i need to have more SDRAM than original 4M*16b.So i ordered 32M x 16b ISSI IS42S16320d-7TL that fit's inside the same footprint, and i soldered single jumper cable to PG2 as well as modified G...
