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...
dear：PH0-OSC_IN：12.288MHZ，duty=50%。but MCO2(PC9) output clk is 35%。can you help me？
Hello my friends,I am trying to setup an I2C slave that is being addressed with a read-request and then answers a fixed number of bytes. I was trying to find out what the XferOptions do, but after I could not find out I went through the HAL-driver co...
Hi everybody,first an apologies for my poor English.I'm using STM32G030K8 in my project and I want to use eeprom emulation to save some parameters. I used the following code, however It didn't work. I spend a lot of time but I can find the problem. v...
Hi, I am trying to implement PWM generation on PC06 from TIM8. The cubeMX is showing following warnings and not generating the clock on desired PIC_PC06??RGB LED is Adafruit NEO Pixel 7 https://www.adafruit.com/product/2226See the attached images and...
In attempting to figure out how to stay in the bootloader loop while exchanging packets with the USB DFU tool I came across as what looks like an unintentionally undeleted line of code.Here is the code:static void OPENBL_USART_Go(void) { uint32_t a...
Hallo everyone,Since some time I struggle to get DMA access working on a STM32H723. I was pointed out this MCU is a complicated beast, but I would at least expect sensible, coherent documentation for it.When I look at page 683, I see:on next pag...
Heyho,so I was just checking the MCO1 output of my STM32H733ZGT6 and found some super jittery 64 MHz with full swing between 0V and 3.3V.Then checked my code and found that I had not set the RCC->CFGR and not even initialized the GPIO.When I actually...
HelloI am looking for an example to get the ADC regular sequence transferred by DMA to memory going.I use TIM15 to trigger the ADC regular sequence, which has four measurements, every 5 milliseconds. When I activate the EOS IRQ and toggle a GPIO I se...
Hi, req is generate sine wave and manage frequency precisely . My design require range 2Hz to 10Hz with for example step 0,002Hz.My idea is one PWM timer for sine with same table for exampel 10bit. Second linked timer for manage one sample time on PW...
Hello, we intend to implement a time-dependent channel change via the operational amplifier in voltage follower mode, as described in AN5306 - Rev 1 Page 31, 5.1. However, when checking the output, there is an unwanted gain (x2) on channel 2. Any ide...
