I am working on an isolated monitoring system for currents, voltages, and heatsink temperatures, and am using the ADCS on the Nucelo-F446RE to take the readings. Initially testing was going well demonstrating good linearity and accuracy across a rang...
Post Edited by ST moderator to apply source code formatting and translate from Chinese to English to comply with the community rule: Best regards, Gyessine Hello everyone, I am trying to implement the 6-Step Trapezoidal Control using the COMG event i...
Can i use UART + DMA ( normal ) + RTO ? I try to add RTO but when activate RTOE bit the DMA buffer stops fills .I take interrupt with active RTOF , stop DMA , but nothing in buffer !? I use stm32H7 with hardware implemented RTO. Can some one to give...
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
Hi everyone,I'm having a hard time with the FDCAN on a NUCLEO-H723ZG. I’ve tried several setups (external with transceivers, external loopback with wires), but I’ve stripped everything back to Internal Loopback mode on FDCAN1 to simplify things.Curre...
Hello,I am attempting to measure the current consumption of an STM32L4 before and after entering STOP2 mode using a DC power supply. I expected the initial current of 165mA to drop down to the $\mu A$ range upon entering STOP2 mode, but it only decre...
Greetings ST Community,I am a junior embedded developer, and I have recently worked on a project utilizing some old systems which run on the STM32L100R8T6TR chips. I had a need for an unique chip identifier for use in a communication protocol, and th...
CASE 1:I am using sdmmc for SDIO bulk transfer at 400khz initially then switch to 25 mhz.Its not working with nucleo h743/53 where cpu frequency 480 mhz and sdmmc input clock is 480 mhz.Its working with nucleo h743/53 where cpu frequency 480 mhz and...
I am implementing a CAN communication structure with one master and two slaves. Both slave devices perform exactly the same function, meaning their hardware and firmware are essentially identical. The master’s intention is to send commands only to a ...
Hi,We have STM32N6570-DK and are testing camera input, video encode and write to SD cardWe have not been able to make the "VENC_SDCard_Appli" example work, the SD card just contains zeros.The "VENC_SDCard_ThreadX" example does work however, resulting...
