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...
The new STM32H7R/S lines are built on the success of the STM32H7 series, offering even higher performance and security at a lower cost. The STM32H7R/S is a bootflash-based MCU powered by a Cortex®-M7 core running up to 600 MHz, with 64 KB of user fla...
Hi everyone,I'm using the STM32F4 Discovery board to communicate with DC Power Supply Programmable ODA OPM Series using RS232.Now, I can send SCPI commands to device (OUTP ON, OUTP OFF, VOLT 10,...), but when I send some query commands, I can not rec...
So,I set my DMA at circular mode ,adc at continuous mode ,but when I debug the timing to get into HAL_ADC_ConvHalfCpltCallback(),I found the buffer is already fulled,can someone tell me what's going on?
This question does not show any research effort; it is unclear or not usefulI am pretty a newbie in display control and I am struggling with my simple application. I need to calculate some numbers on my nucleo and then display them on a screen. Since...
Hello, I have a problem with threads. All of them are of same priority, with osDelay(300), except the uartThread which has osDelay(1). Everything else is the same for all threads. I have allocated 20k of HEAP and in ioc file it says im using only 3.5...
I have been simulating errors on the bus by removing the other node (a motor controller). As expected I see a number of failed transmissions. I can see that the FDCAN peripheral signals an Active Error on the bus (presumably as a result of not gettin...
Hello All, I am trying to write a baremetal code for ADC, to work in Continous SCAN mode. I needed help with a few bit in internal ADC peripheral in STM32F401RE1. EOCS As per the RM, if EOCS is "1" then EOC is set for each conversion,hence suppose...
Hello,What is the best way to multiplex an output pin to 12 output signals? I currently have 1 output sourcing 3.3v through a 1k resistor which works well, but need it multiplexed to 12 identical outputs. I see the STM32F373 has a max rating of 15m...
Hello, I am a little confused here, AN392 claims to run STM32C0 from a 5V power supply, directly from the main fed RCD dropper with a 5.6V Zener. But the datasheet says the maximum voltage is 4V.So does the AN suggest running way over max specs or is...
Hello everybody! I have a sine-wave array, that I throw to the DAC, triggering it by TIM6. When the TIM6 interrupt routine is responsible for supplying samples - everything works fine, but when I try to use DMA nothing works. The DMA keeps spitting t...
Hi, I want to make communication between stm32h563zit6(Nucleo-H563zi) via USB communication, i have tried configuring various UART/USARTS but not able not make communication.I had verified it by sending some data from stm32 ,and tried to see it on ...
