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...
I am using STM32f207zg Nucleo MCU board . I tried to implement Ethernet [lwip library] code. But I have got memory issue. There is insufficient memory. It gives compilation error. How to solve this problem? Guide me for Ethernet programming .
Hi,I try to use both HAL and LL library for UART. When I config UART with cubeMX for LL library, I found all functions with HAL library in my code doesn't work. when I say it doesn't work, I mean the code passed compiling but doesn't do anything. Th...
I am trying to send a uint8 through the "Input Data" port on the I2C_Write block. According to the I2C polling example the block expects a uint8. However, when I build the C code and look at it in Keil I get an error in the "User's Data declarations...
Hi,My Question is related to the PHY LAN8742 mounted on that board. GPIO Configuration for this part is OK, but obvioulsly the 25Mhc clock generator is not working, and i guess this is the reasonfor no response from the PHY. I expect a 25Mhc signal...
Hello, We have a design whereby one of the STM32 RX inputs is driven hi by an external unit before the STM32 is powered up. This somehow prevents the STM32 from booting when power is applied to the STM32. We can manually reset the STM32 after that an...
Posted on June 25, 2018 at 07:11Hi All, I'd like to print float value with printf.when I tried, printf showed blank for float value.would you please let me know how to set TrueStudio for printing float value with printf ?I'm using STM32F103RF.Thanks...
I use STM32CubeMX and IAR Embedded workbench. I find to test IAR example projets, but i get this error: Fatal error: Cannot connect to J-Link via USB. Session aborted!
Hello!I have a question regarding pwm and the break input function from the comparator. I am using a STM32F303 and generating a complementary pwm outpout with timer20 on ch1 and nch1 with a deadtime. This is working just fine. Now I wanted to implem...
