Hi,We have now a problem with some boards, H7A3ZI or H743ZI , when switching off : RTC stops working !RTC is powered on VBAT with a standard CR2032 and was working as it should on about 500 boards since more than a year. Now (some) batteries loosin...
I followed this tutorial https://medium.com/@pasindusandima/stm32-usb-virtual-com-port-vcp-bc7cb1bd5f5 to set up a USB data transmission from my board to a Virtual COM Port. After building the project and running with debugger, I only see "STMicroele...
I have my OCTOSPI1 as QSPI working - in "indirect mode", now using DMA: it generates a very clean waveform (no gaps between words or bytes as in "polling mode", a smooth waveform).I use also OCTOSPI1 as a "regular SPI transmitter" (acting as SPI Tx)....
Hi, I wonder if someone can recommend an alternative to STM32H563ZIT6 mcu for minimum 11 Uart peripherals ona single IC. Preferably if the IC is from the STM32F series.NOTE: The above quantity achieved by treating the USART ports as UART using 144 pi...
Hi ,I am using an STM32F205 for my project. We were using HSI as the clock source before and found out that HSI will not work very well with high temperatures for UARTs, So we added an External crystal clock (16Mhz) but I am unable to get Comms out o...
I used STM32F072C8T6.ADC - IN0, IN1 set.An application that measures temperature with an NTC temperature sensor. PullUp resistance 10K was connected to Vdd (3.29V) and PA0, PA1..When the HAL_ADC_Start_DMA function is executed, the voltage of ADC ...
I'm seeing strange behavior trying to write to the ADC1_JSQR register. This register controls the channel sequence and the trigger source of injected conversions. After enabling the ADC (ADEN=1), a write to bits 7:0 (JEXTEN, JEXTSEL & JL) locks out f...
I've been testing ST chips and started with the STM32F411 using my own board for testing with the SD card, which I wasn't able to get working. Thinking it was my fault, I ordered the STM32F412 Discovery board and I can confirm that using the examples...
Hi ST SupportI would like to request the FIT report for the STM32L071CZT3, many thank.
Hi, Is there a LL Library project example or at least a code snippet of how to transmit uart data using the GPDMA?
