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...
We have a question about the memory map in section 3.1 of AN4839. The note states that "by default the MPU is disabled and that in this case the memory map is defined as the default address map".Immediately under this statement is a table with a memo...
Hey,I'm basicly filling a tank with liquid and I have 2 level sensors in this tank. These level sensors are connected to GPIO_EXTI of my MCU so when the water reached the sensor level, an interrupt occure. If the tank is filling or emptying, I must d...
I using STM32L4 ADC in my project to sample analog acceleration data. The ADC conversion is triggered by 10kHz timer by which i was able to achieve 10kHz sampling rate using DMA. Now, i wanted to implement oversampling by a factor of 2. Now what is m...
When transmitting in endless-transaction mode with the STM32H7 SPI periph. (that is, setting TSIZE = 0), how can I know when the master has finished transmitting all data? Not only that its Tx FIFO is empty (which could be done with TXP) but also tha...
Hi,Since a few minutes, I'm experiencing a problem in CubeIDE v1.10.1 when I try to debug my code. Here is the message I'm getting in the console window:File download complete Time elapsed during download operation: 00:00:00.818 Verifying ... Dow...
Hi,I have the following code to enter shutdown with UART interrupts for the wake up. The processor does shutdown briefly (confirmed with power measurements) and then wakes up after ~.5 seconds. I cannot see any traffic on the serial ports and I can't...
I have 2 memories with not the same type the first is hyperram and the second is nor flash and it is mandatory for my project to use both of them.i am not sure how to do so or if is it possible to use one on the st board and link the other one separa...
using STM32H743ZITWe are using all the serial ports (i.e) 4 UART and 4 USART and all is good. In addition to the UARTS we are using thre I2c, and CANWhen attempting to add the LPUart1, the initialization fails. There is no pin assignment error etc. ...
Hi! I am discovering the world of STM32 and currently using a STM32F4 to establish a UART communication (send and receive data). I wrote a pretty basic program to send and receive a message (basically a loop) with a baud rate of 9600. The users manua...
Using an F411, I'm having trouble getting the RTC_AF1 (PC13) pin to trigger while powered only by the VBAT pin. The pin seems to drive correctly when VDD is active (tried both Wakeup and Alarm A), but removing VDD does not have the same effect. Is th...
