Using STM32F030 / F042. I have a GPS receiver onboard which produces a very accurate pulse-per-second signal (~40ns). I want to use this timing source to keep the system clock, or at least the RTC accurate. The user may wander in and out of GPS recep...
How does one define the filter for a CAN A message, when the ID is only 11 bits?If using 16-bit filter, what should be put to the EXTID[17:15]?
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...
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...
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...
