STM32 MCUs Products

What exactly happens when the Main flash memory (User application code) is selected as the boot area?

I've gone through the STM32 boot processhttps://community.st.com/s/article/faq-stm32-boot-processAfter the boot mode configuration is resolved by means of the BOOT0/BOOT1 pins or the nBOOT0/nBOOT1 (from the option bytes); the controller chooses the s...

Send COMP output to 2 TIMs as follower and inverter.

I want to generate differential signal from this MCU itself. I'm using NUCLEO-H723ZG doing this which has DAC, COMP and TIM built-in.I've used 2 DAC for generate 2 simultaneous UART signals (If there's other ways to do this please recommend) but it's...

How to send another START bit during an I2C transmission

Hi,I am trying to set the FRAM memory mb85rc64ta in sleep mode (Datasheet: I cannot copy and paste a link, but it is from Fujitsu and the pdf file is called MB85RC64TA-DS501-00044-4v1-E page 11)It requires 2 START condition but no STOP condition befo...

How do you use DMA transfers on DAC2 (not DAC1 Channel 2) on a STMH7A? Looking at the memory block diagram it seems that bdma2 has limited scope (does it only have access to the SRD Ram of 32k?) Even if this is the case 32k would be fine... How?

how can we send binary data on two different pins simultaneously on both the rising edge and falling edge of dclk whose speed can be 1MHz on stm32f4?

PCA is managed by a full-duplex serial interface. A typical data frame is defined bya burst of 8 DCLK pulses followed by an assertion of a DLOAD pulse (these lines are driven by the host printing system.). During each frame, 32 bits of control or pri...

STM32 Custom OTA Dual Bank Config

Hello There,I'm working on OTA application and successfully executed single bank OTA.Now I'm looking to switch to Dual bank operation to make it more reliable. So, there are 2 banks (memory areas) and after each update, the active bank changes. Means...

How to implement Pulse counter on STM32H723?

Hi,In our application we are using a cooling system(i.e., a FAN/DC motor). For which I have implemented TIM1 in PWM mode to control the speed of the FAN, the story doesn't end here. The FAN provides a feedback which is called as pulse sensor which ca...

I use mcu (stm32l452rct6) + sensor("ADI" ADXL355). the interface is SPI. How to read sensor data???

Cannot send break condition via uart.I have a nucleo board 32l422 and i connected lora rn2483. I can communicate with module but when set this to sleep i cannot wake up module.I tried HAL_LINSendBreak with no success.

LORA DATASHEETThe default settings for the UART interface are 57600 bps, 8 bits, no parity, 1 Stop bit,no flow control. The baud rate can be changed by triggering the auto-baud detectionsequence of the module. To do this, the host system needs to tra...
