Posted on August 07, 2013 at 21:21 I'm confused about the FIFO error flag (FEIF) when I set up DMA for direct mode transfers. As I understand it, in direct mode the FIFO is disabled. But for some reason, if I enable the FE interrupt in the DMA_S...
Hi!I'm an EE designing a PCB. Referencing the datasheet: https://www.st.com/resource/en/datasheet/stm32l412k8.pdfSection 7.4 on page 178, UFQFPN48, the Exposed Pad (EP) says that it should be connected to GND.Section 7.6 on page 184, UFQFPN32 (the ch...
Hi,i'm trying to upload my firmware with FDCAN system bootloader in STM32H563.As this article(https://community.st.com/t5/stm32cubeprogrammer-mcus/fdcan-programming-support/td-p/199854) says that ST link debugger and STM32 cube programmer don't suppo...
Heyho,just checking the migration guide AN5293 for some peripherals I have not yet ported from F7 to H7:if not mentioned in the document, are the peripherals completely and 100% identical (registers & bits) ?Just checked for I2C, and it is not mentio...
When I send data from esp32 to stm32, it works fine. But when esp32 initially receives data from stm32 using uart, the data seems to have some random characters.When i send 75, it looks like this in serial monitor:Received: %$^#^12Received: 12Receiv...
I have developed a custom controller that uses the STM32G474RE to regulate the output voltage of two power supplies.I am now developing the code to implement a peak-current mode controller for each of the two power supplies. Is there a way that I ca...
I have connected 100k NTC with 100K PU resistance. ADC is measuring voltage on NTC is 1580 mV. While multimeter shows 1410 mV. 1410mV is correct number as it gives 32 degC temperature.I am using ADC in polling mode. I added HAL_ADCEx_Calibration_St...
HI,I'm working with a micro from the H7 family (H723).I have to implement CAN communication on two distinct peripherals (FDCAN1 and FDCAN2) in interrupt mode but the system doesn't work.Below are the settings I use in my project: void MX_FDCAN2_Init(...
Hii everyone!We are working on CAN , and MCU is stm32f103When we are taking output on blue-pill Tx and Rx pin Data is comingBut when are are doing same on custom board data is not showing ,we are uploading same firmware and clock configuration is als...
