I'm using uart fuctions with my board STM32F401RE.I don't use cts, rts (hardware flow control) and any receiving process.So I only transmitt some values to PC but I found that when I send a message constantly, suddenly it stop. I think it's related w...
When we did EST test in the lab, the board was burn by the electrostatic.how can avoid it？Thanks
Posted on August 11, 2015 at 04:28Hi guys,I wanted to test DFU function with my STM32F401 board, and my Win7 has installed DfuSe V3.0.4. After I plug USB to PC, it shows the driver is not corrected, so DfuSe can't recognized the USB device.I searche...
Posted on May 25, 2016 at 23:27I used stm32cubeMX to generate a CDC project for the stm32f3 discovery board. After much fussing, I have a pretty stable echo going. If I use a program to generate output/input from the host, I'm finding writes of 64...
Hi I have been reading an ST presentation regarding using the internal opamp on a STM32L433. Am I reading it correctly, this saves in having to use an external opamp? I want to use it for as a follower for the analogue input. I am not sure I am read...
Hi, I want to run DSP lowpass filter and also run other applications like voice over ble and touch screen interrupts at the same time. running one after the other is not efficient.Is there a way to run these applications in parallel on a stm32 proces...
DMABR->SR should be auto-cleared when set 1.I haven't modified code - auto generated by hal.It always timeouts - any ideas why? I tried to extend timeout time - bit 0 is always 1.Here is code from HAL: /* Ethernet Software reset */ /* Set the SWR ...
Do you know the power consumption difference between STM32L0+ series and STM32G0 series? Which is lower? I'm using STM32L0+ series. If STM32G0 series consumes lower power, I'll switch to it.
