Hello, I'm designing a new Board base on the STM32F405RGT and i want to use a 12MHz crystal from JLCPCB with this references C9002 Yangxing Tech|Yangxing Tech X322512MSB4SI|SMD Crystal Resonators|LCSC. Is this crystal a 20pf? and did any one use it ...
I'm trying to simulate a quadrature encoder signal coming out of an automotive car seat motor. I don't have the motor but I do have the hall sensor used in it (Allegro A1221LLH). The Vout from the sensor is not accessible in the motor and its a 3-pin...
I've tried to work it with android Emulator on PC, but it can't activate the Bluetooth for communicating with the evaluation board
-Using the HAL in STM32 Cube IDE.-I can examine the FLASH pointer in the hard fault ISR and the registers appear to be just like when accessing any other page.-I am unlocking the Flash and the option bytes.-I have not modified the option bytes.-It do...
I use a LM4040 voltage reference IC to generate a 3.00V reference voltage for the STM32G0 VREF+ pin. The resistor is 750 ohms, so 4mA can be sourced to the VREF+ pin (the datasheet specifies a minimum of 500 uA). I use the STM32G0 DAC (channel 1 only...
Hi everyone ,İs there any library to communication with db ? Which one db is does not matter .PS: Of course LWIP already implemented.
Hi, We are using a STM32H745 in our project. Over the past few days, I've been wasting a lot of time figuring out why RTC has a major error ... it always runs slower than it should. To be sure we tried to used the crystal and the capacities present i...
Hi, If you set a timer in Output Compare in Mode "Toggle" and assing a Chanel to a pin of your uC you can make it toggle when CCRx == CNT. That works just fine, as expected. My question is: when you configure the Mode of that Channel to “Active on Ma...
Hi everyone, I try to understand more deeply the the whole clocks issue and how each frequency affects the running time. My board is STM32F429, and the clock configuration set by default (maximum values). This is the best configuration for fast runni...
In RM0008 cha 27.3.4 talks of " Fractional baud rate generation" and goes at length with examples of those fractional number. If the "fractional" stuff is broken down to integers, it boils down that simply baud = f(clk) / BRR.Or, as libopencm3 write...
