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 .I have problem with this back to back timer configuration . (in AN4776)What I get :1- Timer 1 is making PWM ( i just need a regular pwm but this examle is a complementary one )2-Timer 1 will send a trigger to timer2( which is it's controller acut...
I am slightly confused with the ADC Master - Slave configuration. Maybe someone can shed a bit of light in here.Using a STM32G474RET (LQFP64), thinking of chaining ADC1 and 2 in a master/slave configuration. Looking at the attached schematic, PB1 and...
Hello,I'm using a Nucleo F446ZE to test timer capabilities to make a peak-and-hold PWM driver. I already have the core functionality where TIM1 uses DMA to run through a buffer of variable duty cycles at a higher frequency (e.g. 5 kHz) for the high-s...
Please help if you can, but please do me the courtesy of reading in full before replying: We have a product using STM32L475 with a 32768Hz clock on the LSE. When I attempt to tune the crystal oscillator to within the performance spec of the crystal ....
Hi,I am trying to emulate a EEPROM with my STM32F103 as a I2C slave. I'm using STM32CubeIDE 1.0.2.The chip that will request data doesn't write data to the EEPROM, so I can use only an array to save the data in the code. And it cant have any code in ...
In the document UM1775 there is stated the following:"5 V and 3 V can be used as output power supplies when an extension board isconnected to pins P2 and P3....In this case, the 5V_O and 3V_O pins deliver a 5 V or 3.3 V power supply and thepower cons...
I'm using several Nucleo-H743ZI boards. At reset (reset handler) the bit ACTVOSRDY in PWR_CSR1 is 1 on one board and 0 on the other. 0 means "voltage level invalid, above or below current VOS". The current VOS is of course the default one at reset, i...
hi guys. I want to use DMA to change the PWM frequency in the pwm running. I used DMA to change the ARR of Tim, but it was failed. So how to change the pwm frequency by DMA?
Hi,I bought a STM32L476 board. I started with the demo available in keil uVision and it worked fine easily, but it is closed, you cannot modify anything.My question is: may I follow the MOOC with this board? instructions require a different specific ...
