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...
Hello,According to the reference manual RM0456 7.3.3:"Prefetch is enabled by setting PRFTEN in FLASH_ACR.PRFTEN must be set only if at least one wait state is needed to access the flash memory" Compared to that I've seen that in the U5 HAL, in the fu...
Hi everyone.I was struggling with openamp library and finally i couldnt handle it.As i understand this library is built to share data between two cores and as i know both cores have access to the whole memory region.So when we want to share for examp...
We are trying to configure TIM1 and an internal comparator to turn-off the TIM1 complimentary PWM outputs on a falling edge event and generate a TIM1 break interrupt.I was successful to do this with a comparator with Rising Edge event.But when TIM1 ...
Hello It's been days now that I'm trying to work with the CAN Communication on the U5A5ZJ-Q. I couldn't find any documentation on it (aside from the FDCAN), Hence, I would like to get some documentation on the board since there are CAN Tx and CAN Rx ...
Hello guys, I have an issue that when I program the board, LED5(it says Vbus LED) is lighting. (it is green) Datasheet of the board hasn't got a info or i cant see any info about that.Could you help me with this issue ? Thank you...
I have a Nucleo-l432kc board that I actually fried by accident touching one of the pins with my power supply probes while they shared the same ground during a risky test of mine anyway the problem now is I can't find a replacement at the moment in my...
I have a STM32U595 with a 32.768kHz LSE oscillator.I wish to generate a 1ms/1kHz timebase with the accuracy/drift characteristics of the LSE, so naturally I went to make use of the "Hardware auto calibration with LSE (PLL-mode)" feature.Firstly, can ...
Hello eveyone,I'm trying to communicate with MODBUS TCP between a STM32 Nucleo-F429ZI board and a PLC. There is a LAN8742A transceiver on the board, do you know any modbus TCP library that is compliant with ?Thanks in advance for you time
I implemented a STM32 flash loader for an external spi flash. As you can see in the STM32CubeProgrammer log (appendix), the write sequence always fails.After long time debugging i tracked the issue down to the function call:LL_SetSystemCoreClock(6400...
Hi guys:I had a project with a bootloader and an application, let me call them "BT1" and "APP1".I want to rewrite the "APP1" and already done, let me call the new app "APP2".Now the "BT1" can jump to "APP1", but can't jump to "APP2", I am sure the ap...
