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'm using the STM32F767ZI MCU and with its RTC function. But my quartz crystal is not accurate. According to the document of the MCU, the accuracy can be calibrated (it said in page 35/255: Digital calibration circuit with 0.95 ppm resolution, to com...
I found a version macro in the library but it seems to be wrong. Please see attachment. What should I do to check the SPL version in the code?
Hello, We are developing a watch-like wearable device with LCD. STM32L4R-Discovery board is a nice reference design for STM32L4R+AMOLED development. It would be also nice to have a schematic for the adapter board MB1314B, which the AMOLED is attached...
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...
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...
