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...
Hi All,I am able to generate OPM pulses using Timer 1 of L4R5ZI MCU.Problem is - I want pulse train having 20 pulses first time. Once they are generated, after ~5ms delay, I want another pulse train having 5 pulses. This is not working. OC1 pin has p...
Hi,I am trying to check IWDG functionality on Nucleo-L4R5ZI board.Referring to the example code available for NUCLEO-L496ZG, i created new project for L4R5ZI nucleo. I was trying to go step by step in debug mode. When the debugger is inside HAL_IWDG_...
Hi all,First post on here so apologies if I make some errors in my question format/clarity.I am doing some testing using the SPI HAL library attempting to communicate with another chip, everything works as expected and I can successfully send bytes a...
I need to be able to toggle between 3V and 5V per pin for about 40pins. i.e command output_high_3V would get 3V etc. I am not sure the best way to go about it since STM32 are only 3V3 pins. I was thinking of using GPIO Expanders, or some transisto...
I'm developing for an STM32L0 and trying to use DMA to control the I2c peripheral Tx and Rx. I got it working so far(both Tx and Rx using DMA) but I'm stumped on the reload functionality for the I2c peripheral. Is this even possible? I looked at the ...
In DS12712 Rev 2 (STM32G473) table 13 shows PB10/11 as CAN3_TXFD/CAN3_RXFD but in table 12 CAN is not listed for these pins. Also in tab 13 sometimes it is CAN3_TX and sometimes CAN3_TXFD. Which one is valid ? Interestingly in STM32G474 tab 13 both C...
If I put port b all in analog the micro not wake up when in RTC wakeup mode (internal wakeup).Any help?Thanks in avancevoid EnterStopMode(void){ GPIO_InitTypeDef GPIO_InitStruct={0}; /* Configure all GPIO as analog to reduce current consumption on n...
Our R&D team is trying to use more memory for GUI with STM32F469I.We found the way using QuadSPI interface from the document as below.Unfortunately, the hardware already has completed with parallel Nor Flash memory, S29GL128S-16MB.Is there any other ...
