STM32L152RE Schematic Verification
I am trying to create custom PCB for my academic project. This is the first time i am using an STM32 processor. I will be grateful if someone can verify the schematic for STM32L152RE which i created.I will be using SWD to flash code to the STM32. The...
Resolved! prebuilt Altium design files for the STM32G4 series?
Hi guys - Any idea how long it will take for prebuilt Altium design files for the remarkable STM32G4 series to show up? [I am specifically designing for the STM32G431RBI6, which is a tidy 5mm x 5mm BGA with 8x8=64 balls @ 0.5mm pitch.]. I don't know ...
Resolved! Stm32f042f6 tssop package , when i am powering ,microcontroller is not starting ,even if i use hard reset . its only starting when i connect ST link( SW Debug)
YStm32f042f6 tssop package , when i am powering, microcontroller is not starting ,even if i use hard reset . its only starting when i connect ST link( SW Debug) mode.I am using external clock 8 mhz.I have attached Circuit diagram !! i tried with cou...
What is the correct recommended pad size for the STM32 in the TFBGA240+25? The Table 135 of the datasheet seems incorrect.
With a ball size of 0.4mm I would expect a pad size of 0.36mm , but 0.225 mm is in the table.
Resolved! Updating STM32H743 Nucleo from ST-Link to J-Link
Has anyone succeeded at it? What did you have to do? I've found a lot of success stories about updating the ST-Link on 32F4 boards but none on the H7. When I run stlinkreflash.exe I always getPreparing for FW update (can take up to 10 seconds)...ERRO...
OHMs between VSS and VDD falls down to minimum value.and CPU RUN led turned off within few minuits.
we are developing HMI(ethernet,sdcard,4.3 inch tft touch display) using STM32F746 microcontroller with 6 layer pcb,we already did one pcb and its working perfectly.and we started 2nd one almost at the end of the process found random auto reset,cpu ru...
debug breaks when the relays operate. The system continues to run
I design a PCB with a stm32f407.Relays come into play shortly after debug starts. sometimes the debug fails and closes when the relay activates. What should I do to prevent the debug from closing?relays are driven with 24 volts and lm2803.The st link...
For uploading SW with seiral cable(USART) and STMFlashLoader
I developed with uvison5 and STM32F303/030The software was uploaded well with uvison5 and ULink2.But I failed for uploading with serial cable and STMFlashLoader.(my colleague in Germany succeeded it with the manual)But I can’t and I don’t know why.
