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 have an 1.8V STM32 and an 3.5V MAX31865 which are connected via SPI, I used 10k Ohms pullups on data line to 3.5V. Now the problem is that communication dosen't work. When I increas STM32 voltage to 3.5 V everything is fine. Is there an limitation ...
Hi,I am using STM32G474 Nucleo board and try to use TIM1_CC_IRQHandler. I am using TIM1_UP_TIM16_IRQHandler to check certain conditions and then I'll enable the CC1IE bit in TIM1->DIER register.I configured TIM1 as Center-aligned PWM mode.However, I ...
Hi,I'm running into a very strange issue with the CAN module. When enabling ABOM on CAN2, some but not all of the FIFO1 RX interrupts are missed. As soon as I disable the ABOM setting, everything works as expected. Has anyone seen this behavior be...
Hi--I/m pretty stumped. I am trying to implement a odd parity configuration for USART1 in an stm32L452RE micro. I've confirmed without parity the usart behaves as expected at the needed baud. When i introduce parity into the code and sniff the data o...
Form, Fit and Function Alternate for Part STM32F070RBT6 as this is not procurable at the time, we need an alternate that can fit into design without any software or hardware modification.
HiI'm using the HAL_SPI_TransmitReceive_DMA to write to an external Flash. On a delte command for the external flash I need to wait for until the busy flag of the flash is zero. So I use this function to check the busy flag. spi_read(&command, sizeo...
Hello everyone, I use a STM32F407VET6 MCU board and I'm trying to implement a Timer 8 Interrupt, every 5u sec. In my code, I also use an ADC interrupt, for ADC conversion purposes. I thought that these 2 interrupts are independent. I observed that w...
HiI've set the jtag pins in my code to analog input (non intentionally) .While I was able to connect to Device (STM32H743) after I managed to erase the flash option bytes (with mass erase) using j-link stm32 tool (No St-Link option or SWD for me on ...
Hi,I have some code running on a Nucleo-STM32L476 which keeps running into the Reset Handler. But this does not cause a boot loop, instead the code just gets stuck there (the PC register points to the first line of assembler of the reset handler).I m...
