Is it necessary to enable interrupts in I2C_CR1 if I only want to look at the flags but don't want to go into the interrupt service routine? For instance, I want to be able to look at the status of RXNE and see if it is set, but I don't actually want...
Hello,I originally tagged onto this thread: https://community.st.com/t5/stm32-mcus-products/stm32f103-hse-crystal-capacitors/td-p/771200 but I was recommended to make a separate thread. Many of the STM32 datasheets, such as the STM32H753, say that th...
Hello Which are the correct Capacitors to use for HSE on STM32F103 with the following Crystal?Frequency: 8 MHzLoad capacitance CL: 20 pF Thank you in advance for a quick hint.RegardsMichael
Posted on July 10, 2018 at 14:37I've been designing sub-gram boards for data logging on songbirds using the stm32l432. Although mostly I use ultra-low power external RTCs, I recently built a test board using a 4pf 32768 crystal. The question was t...
Hello, I'm using an STM32H750VB and am trying to use the HSE crystal to communicate over USB to my computer, but it isn't able to connect to my computer. I suspect that the issue lies with the crystal since I tried to probe it with an oscilloscope an...
Hi,I have developed custom board with STM32C071CBT6. I configured USB port with USBX in CDC mode. I configured USB device descriptor values as below: When I connect host Windows 11 PC to my custom board, device manager on PC shows - USB Serial Device...
The STM32L052K8u Bootloader is replying to my GoToAddress command with 0x3F. I can't find any documentation that describes reply code 0x3F.The entry in my STM32L052K8UX_FLASH.ld file says this:/* Memories definition */MEMORY{RAM (xrw) : ORIGIN = 0x20...
Hi all,I'm struggling to get the ST bootloader on a STM32L431KUB to communicate with a STLINK-V3SET via CANBUS using the STM32CubeProgrammer, the reported error is ST-LINK error (BRG_CAN_ERR) Establishing connection with the device failed.I have made...
Hello Team,We are using STM32F765IIT7 MCU.We would like to get the radiated immunity document if tested (to get a understanding how good this controller is with single event effect)Kindly share any supporting documents.Best Regards,Yuvakumar
Posted on March 12, 2015 at 15:41 Here's what appears to be a another defect in the STM32F373 (See /a7981b0 /638d212). When you configure the SAR for externally triggered group conversions (the code example provided here is for regul...
